This information can help nurses make informed decisions about patient care.

How do I do a Critical Analysis?

There is no one way to do a Critical Analysis. However, there are some key steps that you should take into account when undertaking this type of analysis:

1) Read the text or piece of media carefully;

2) Identify the main themes and ideas presented in the text;

3) Analyze these themes and ideas in depth;

4) Weigh each theme and idea against one another;

5) Write your analysis in an objective manner;

If you are a nursing student looking to learn how to write a critical analysis, you have come to the right place. In this article, we will teach you the basics of writing a critical analysis, including what to include and why. We will also provide some tips for how to structure your essay so that it is clear and easy to read. Finally, we will provide a sample critical analysis of a fictional novel to help you get started.

There are a few steps in writing a critical analysis of literature. In this article, we will discuss the different steps involved in writing a critical analysis and give you an example of how to go about it.

Step One: Choose Your Literature

The first step is to choose the literature you would like to analyze. This could be anything from a journal article to a novel. Once you have chosen your work, it is time to read it with an open mind. When reading any piece of literature, try to focus on the author’s purpose and message. Note what is important to them and how they communicate their ideas. After reading the work, take some time to formulate your thoughts about it in writing.

Step Two: Analyze the Text

Once you have formed your thoughts about the text, it is time to begin analyzing it. In order to do this, you will need to pay close attention to the author’s use of language and structure. Do they use specific words or phrases frequently? Why or why not? How does their choice of words affect their meaning? Are there any specific passages which stand out as particularly effective or ineffective? Once you have analyzed the text,write down your thoughts in a clear and concise manner.

Step Three: Evaluate the Theme and Ideas

Once you have analyzed the text, it is time to look at the main themes and ideas. What are they? What does the author want readers to take away from the work? Are the themes consistent throughout the text? How do the different themes connect? Once you have identified the main themes and ideas, write about them in your analysis. Do you think they are effectively communicated? Are there any elements of the text that you don’t agree with?

Step Four: Consider Your Opinion

After analyzing and evaluating the text, it is important to share your thoughts with readers. In writing a critical analysis, it is important to be objective. This means that you should not express your own opinions or biases in your writing. Instead, focus on providing readers with an objective perspective on the work. Is it worth reading? Why or why not? Is there anything else you would like to say about it?

43.2 Developing Critical Thinking

Learning objectives.

By the end of this section, you will be able to:

• Analyze the types of thinking used in nursing
• Recognize when to use the different types of thinking in nursing
• Explore the application of knowledge to thinking in nursing
• Appy Critical Thinking Indicators (CTIs) to decision making

Thinking is something we usually do subconsciously, because we are not usually “thinking about thinking.” However, with the ever-increasing autonomy being afforded to nurses, there is also an increased need for nurses to be able to critically think effectively and intentionally. Being able to critically think helps nurses’ problem solve, generate solutions, and make sound clinical judgments that affect the lives of their patients. Keep reading to learn more about how nurses use critical thinking in practice and how you can develop your own critical thinking skills.

Types of Thinking Used in Nursing

Nurses make decisions while providing patient care by using critical thinking and clinical reasoning. In nursing, critical thinking is a broad term that includes reasoning about clinical issues such as teamwork, collaboration, and streamlining workflow.” On the other hand, clinical reasoning is defined as a complex cognitive process that uses formal and informal thinking strategies to gather and analyze patient information, evaluate the significance of this information, and weigh alternative actions. Each of these types of thinking is described in more detail in the following sections.

Cognitive Thinking

The term cognitive thinking refers to the mental processes and abilities a nurse uses to interpret, analyze, and evaluate information in their practice. Basically, it encompasses how nurses think about the practice decisions they are making. Cognitive thinking and critical thinking go hand in hand because nurses must be able to use their knowledge and mental processes to devise solutions and actions when caring for patients. Using critical thinking means that nurses take extra steps to maintain patient safety and do not just follow orders. It also means the accuracy of patient information is validated and plans for caring for patients are based on their needs, current clinical practice, and research. Critical thinkers possess certain attitudes that foster rational thinking:

• confidence: believing in yourself to complete a task or activity
• curiosity: asking “why” and wanting to know more
• fair-mindedness: treating every viewpoint in an unbiased, unprejudiced way
• independence of thought: thinking on your own
• insight into egocentricity and sociocentricity: thinking of the greater good and not just thinking of yourself. Knowing when you are thinking of yourself (egocentricity) and when you are thinking or acting for the greater good (sociocentricity)
• integrity: being honest and demonstrating strong moral principles
• intellectual humility: recognizing your intellectual limitations and abilities
• interest in exploring thoughts and feelings: wanting to explore different ways of knowing
• nonjudgmental: using professional ethical standards and not basing your judgments on your own personal or moral standards
• perseverance: persisting in doing something despite it being difficult

Cognitive thinking is significant to nursing because it provides a foundation on which nurses can make rapid and accurate decisions in clinical practice. Nurses must be able to think quickly and make informed decisions to promote optimal patient outcomes.

Effective Thinking

To make sound judgments about patient care, nurses must generate alternatives, weigh them against the evidence, and choose the best course of action. The ability to clinically reason develops over time and is based on knowledge and experience. Inductive and deductive reasoning are important critical thinking skills. They help the nurse use clinical judgment when implementing the nursing process. Effective thinking in nursing involves the integration of clinical knowledge and critical thinking to make the best decisions for patients. For example, if a nurse was caring for a patient who presents with hypertension and new-onset left-sided weakness, it is important that the nurse be able to quickly consider potential causes for the weakness and implement immediate stroke protocols. Without the ability to critically think, the nurse may overlook the weakness as being unrelated to the hypertension and not consider the possibility of stroke, leading to a poor patient outcome. Thus, it is imperative that nurses develop effective thinking skills.

Inductive Reasoning

The term inductive reasoning involves noticing cues, making generalizations, and creating hypotheses. Cues are data that fall outside of expected findings and give the nurse a hint or indication of a patient’s potential problem or condition. The nurse organizes these cues into patterns and creates a generalization. A generalization is a judgment formed on the basis of a set of facts, cues, and observations and is similar to gathering pieces of a jigsaw puzzle into patterns until the whole picture becomes clearer. On the basis of generalizations created from patterns of data, the nurse creates a hypothesis regarding a patient problem. Remember, a hypothesis is a proposed explanation for a situation. It attempts to explain the “why” behind the problem that is occurring. If a “why” is identified, then a solution can begin to be explored. No one can draw conclusions without first noticing cues. Paying close attention to a patient, the environment, and interactions with family members is critical for inductive reasoning. As you work to improve your inductive reasoning, begin by first noticing details about the things around you. Be mindful of your five primary senses: the things that you hear, feel, smell, taste, and see. Nurses need strong inductive reasoning patterns and be able to act quickly, especially in emergency situations. They can see how certain objects or events form a pattern (or a generalization) that indicates a common problem.

Consider this example: A nurse assesses a patient who has undergone surgery and finds the surgical incision site is red, warm, and tender to the touch. The nurse recognizes these cues form a pattern of signs of infection and creates a hypothesis that the incision has become infected. The provider is notified of the patient’s change in condition, and a new prescription is received for an antibiotic. This is an example of the use of inductive reasoning in nursing practice.

Deductive Reasoning

Another type of critical thinking is deductive reasoning ; it is referred to as “top-down thinking.” Deductive reasoning relies on using a general standard or rule to create a strategy. Nurses use standards set by their state’s Nurse Practice Act, federal regulations, the American Nursing Association, professional organizations, and their employer to make decisions about patient care and solve problems.

Think about this example: On the basis of research findings, hospital leaders determine patients recover more quickly if they receive adequate rest. The hospital creates a policy for quiet zones at night by initiating no overhead paging, promoting low-speaking voices by staff, and reducing lighting in the hallways. The nurse further implements this policy by organizing care for patients that promotes periods of uninterrupted rest at night. This is an example of deductive thinking, because the intervention is applied to all patients regardless of whether they have difficulty sleeping or not.

Identify the Purpose of Thinking

Rationalizing the purpose of thinking is probably not something you do often, but it is the foundational first step in critical thinking. To effectively use critical thinking in practice, the nurse must first identify the purpose of thinking. For example, the nurse is caring for a patient who presents with fever, tachycardia, and shortness of breath. The patient also has an open, infected wound on the left foot that is not healing. The nurse must recognize that the patient is exhibiting signs and symptoms that may be indicative of an underlying problem. At this point, the nurse must be able to identify that the purpose of thinking with regard to the patient is to consider what might be happening with the patient and formulate a plan of care. This begins the process of critical thinking, which involves several steps: thinking ahead, thinking in action, and reflection on thinking.

Thinking Ahead

Thinking ahead in nursing involves considering what may be going on with the patient to anticipate potential outcomes and complications that may arise. Remember competent nurses are proactive versus reactive. Reactive nursing is letting situations arise and then responding to the change, but proactive nursing is recognizing cues behaviors and patterns that are leading up to a complicated event. Additionally, the nurse will formulate goals of care and must try to anticipate specific needs the patient will have. Considering the patient discussed in the preceding paragraph, the nurse should begin the process of thinking ahead about potential outcomes and complications. The nurse may hypothesize that the patient is starting to develop sepsis from the open wound on the foot so severe sepsis and/or septic shock could be a complication to begin preparing for. The nurse thinks ahead about goals of care for the patient and determines that wound care to prevent infection spread and sepsis is the priority goal at this time.

Thinking in Action

Thinking in action encompasses the thought processes occurring while the nurse is performing interventions. So, if the nurse in our example begins performing wound care, they are thinking about the best dressing to use, how to clean the wound, and if antibiotics should be considered. All of these thoughts are likely occurring as the nurse is providing the care; thus, they are examples of how the nurse is using thinking in action.

Reflection on Thinking

After performing interventions or making decisions, the nurse should reflect on the thinking that occurred. The nurse will use this thinking process to determine if the decision was reactive or responsive. Reactive decision-making involves responding to situations after they have occurred, often in a hurried or unplanned manner. These decisions tend to be impulsive and are driven by immediate needs or crises. Responsive decisions, on the other hand, involve careful deliberation about how to address a situation based on careful consideration of information. In our example, the nurse’s decision appears to have been responsive. The patient was exhibiting some altered vital signs, but nothing indicated that the situation had become emergent yet. The nurse was able to think carefully about the patient’s situation and determine that wound care was the highest priority and begin to implement care in a calm, deliberate manner. In an ideal world, all nursing decisions would be responsive, but in a lot of cases, they must be reactive because of situation severity and medical emergencies.

Application of Knowledge

During the outset of the critical thinking process, nurses must judge whether their knowledge is accurate, complete, factual, timely, and relevant. This can be done by applying knowledge to nursing practice in a multitude of ways, including drawing from past education and experience in nursing and using professional resources and standards. Each of these is discussed in more detail in the following sections.

Knowledge Base

Becoming a nurse requires years of schooling, which contributes to the development of a robust knowledge base. Nurses receive formal education and training that provides them foundational knowledge in anatomy, physiology, pharmacology, and patient care techniques, among many others. Additionally, nurses are required to complete continuing education courses specific to their chosen practice setting, further developing their knowledge base. When applying knowledge in practice, nurses can draw from their knowledge base and make informed decisions about patient care.

Experience in Nursing

Nursing is considered a practice. Nursing practice means we learn from our mistakes and our past experiences and apply this knowledge to our next patient or to the next population we serve. As nurses gain more experience, they can use what they have learned in practice and apply it to new patient situations. Each new encounter with a patient presents unique challenge and learning opportunities that contribute to the development of clinical expertise. Reflecting on these experiences allows nurses to recognize patterns, anticipate patient outcomes, and refine their decision-making processes. Whether they are identifying effective nursing interventions for common conditions, adapting care plans to individual patient needs, or navigating complex situations with compassion, nurses draw upon their accumulated knowledge base from clinical experience to provide high-quality, patient-centered care. Through reflection and continuous learning from past experiences, nurses enhance their clinical skills, ultimately improving patient outcomes.

Professional Resources and Standards

In addition to foundational knowledge bases and experience, nurses can also use professional resources and standards to gain and apply knowledge in practice. Nurses can refer to clinical practice guidelines that have been established by professional organizations and healthcare institutions to help provide a framework for implementing nursing interventions based on the best evidence. By following the guidelines, nurses are ensuring that their care aligns with established standards and promotes optimal patient outcomes. Additionally, nurses should remain up to date about new and emerging research in their practice area, which can be obtained by reading professional journals and publications and attending conferences, workshops, and other trainings. Nurses can use the information learned from these resources to influence practice and ensure the highest standards of care are being performed in their practice setting. By staying informed about the latest developments in nursing and health care, nurses enhance their knowledge base and can adapt their practice to incorporate new evidence and innovations. Along with professional development and staying current with professional practices, nursing students should actively seek and join professional organizations such as critical care nursing or oncology nursing societies because this will lead the student to become expert in that subject and stay relevant with current evidence and practice guidelines.

Clinical Safety and Procedures (QSEN)

Qsen competency: evidence-based practice.

Definition: Providing quality patient care based on up-to-date, theory-derived research and knowledge, rather than personal beliefs, advice, or traditional methods.

Knowledge: The nurse will describe how the strength and relevance of available evidence influences the choice of intervention in provision of patient-centered care.

Skill: The nurse will:

• subscribe to professional journals that produce original research and evidence-based reports related to their specific area of practice
• become familiar with current evidence-based clinical practice topics and guidelines
• assist in creating a work environment that welcomes new evidence into standards of practice
• question the rational for traditional methods of care that result in sub-par outcomes or adverse events

Attitude: The nurse will appreciate the importance of regularly reading relevant professional journals.

Critique of Decision

After determining the best course of action based on the application of knowledge, the nurse can critique the decisions that were made. Specifically, the nurse will use self-reflection to review their actions and thoughts that led them to the decision. The nurse will consider the outcomes of their chosen interventions, reflect on the effectiveness of their approach, and identify areas of improvement. Additionally, the nurse may seek feedback from colleagues to obtain different perspectives about decisions made. Soliciting input from others helps the nurse gain insight and learn from their peers to further inform their future practice. Reflection questions that the nurse may ask themselves to critique their decision include the following:

• Was the patient goal or outcome met?
• Could the intervention have been done differently? Could it have been done better?
• What are alternative decisions that could have been made? What are the merits of each?

Critical Thinking Indicators

Certain behaviors that demonstrate the knowledge, skills, and attitudes that promote critical thinking are called critical thinking indicators (CTIs) . Critical thinking indicators are tangible actions that are performed to assess and improve your thinking skills.

4-Circle CT Model

There are many models and frameworks within nursing and other disciplines that attempt to explain the process of critical thinking. One of the most popular is Alfaro-LeFevre’s 4-Circle CT Model (Alfaro-LeFevre, 2016). This model breaks critical thinking into four components: personal characteristics, intellectual and cognitive abilities, interpersonal abilities and self-management, and technical skills. These four components overlap, forming interconnections in critical thinking.

Link to Learning

Learn more here about the 4-Circle CT Model and see an illustration of it.

Personal Critical Thinking Indicators

Personal CTIs are behaviors that are indicative of critical thinkers. Some of these behaviors that are most relevant to nursing include:

• confidence and resilience: showing ability to reason and learn and overcoming problems
• curiosity and inquisitiveness: asking questions and looking for the “why” behind things
• effective communication: listening well, showing understanding for others thoughts and feelings, and speaking and writing with clarity
• flexibility: changing approaches as needed to obtain the best results
• honesty: looking for the truth and demonstrating integrity while adhering to moral and ethical standards
• self-awareness: being able to identify one’s own knowledge gaps and acknowledge when thinking may be negatively influenced by emotions or self-interests.

Personal Knowledge and Intellectual Skills

Personal knowledge and intellectual skills encompass the knowledge gained from nursing school and clinical experiences. Examples of each of these kinds of skills are listed in Table 43.3 .

Interpersonal and Self-Management Skills

Interpersonal and self-management skills encompass the knowledge and skills needed for effective collaboration. These include:

• addressing conflicts fairly
• advocating for patients, self, and others
• dealing with complaints constructively
• establishing empowered partnerships
• facilitating and navigating change
• fostering positive interpersonal relationships and promoting teamwork
• giving and taking constructive criticism
• leading, motivating, and managing others
• managing stress, time, and energy
• promoting a learning and safety culture
• upholding healthy workplace standards
• using skilled communication in high-stake situations

Technical Skills

Technical skills in nursing refer to the practical abilities and competencies that nurses use in the delivery of patient care. These skills are typically learned through education, training, and hands-on experience. Some common technical skills in nursing include:

• administering medications
• assisting with personal hygiene and activities of daily living
• documentation and charting
• inserting intravenous catheters
• inserting urinary catheters and nasogastric tubes
• performing tracheostomy care
• performing wound care
• taking vital signs

What is Critical Thinking in Nursing? (Explained W/ Examples)

Last updated on August 23rd, 2023

Critical thinking is a foundational skill applicable across various domains, including education, problem-solving, decision-making, and professional fields such as science, business, healthcare, and more.

It plays a crucial role in promoting logical and rational thinking, fostering informed decision-making, and enabling individuals to navigate complex and rapidly changing environments.

In this article, we will look at what is critical thinking in nursing practice, its importance, and how it enables nurses to excel in their roles while also positively impacting patient outcomes.

What is Critical Thinking?

Critical thinking is a cognitive process that involves analyzing, evaluating, and synthesizing information to make reasoned and informed decisions.

It’s a mental activity that goes beyond simple memorization or acceptance of information at face value.

Critical thinking involves careful, reflective, and logical thinking to understand complex problems, consider various perspectives, and arrive at well-reasoned conclusions or solutions.

Key aspects of critical thinking include:

• Analysis: Critical thinking begins with the thorough examination of information, ideas, or situations. It involves breaking down complex concepts into smaller parts to better understand their components and relationships.
• Evaluation: Critical thinkers assess the quality and reliability of information or arguments. They weigh evidence, identify strengths and weaknesses, and determine the credibility of sources.
• Synthesis: Critical thinking involves combining different pieces of information or ideas to create a new understanding or perspective. This involves connecting the dots between various sources and integrating them into a coherent whole.
• Inference: Critical thinkers draw logical and well-supported conclusions based on the information and evidence available. They use reasoning to make educated guesses about situations where complete information might be lacking.
• Problem-Solving: Critical thinking is essential in solving complex problems. It allows individuals to identify and define problems, generate potential solutions, evaluate the pros and cons of each solution, and choose the most appropriate course of action.
• Creativity: Critical thinking involves thinking outside the box and considering alternative viewpoints or approaches. It encourages the exploration of new ideas and solutions beyond conventional thinking.
• Reflection: Critical thinkers engage in self-assessment and reflection on their thought processes. They consider their own biases, assumptions, and potential errors in reasoning, aiming to improve their thinking skills over time.
• Open-Mindedness: Critical thinkers approach ideas and information with an open mind, willing to consider different viewpoints and perspectives even if they challenge their own beliefs.
• Effective Communication: Critical thinkers can articulate their thoughts and reasoning clearly and persuasively to others. They can express complex ideas in a coherent and understandable manner.
• Continuous Learning: Critical thinking encourages a commitment to ongoing learning and intellectual growth. It involves seeking out new knowledge, refining thinking skills, and staying receptive to new information.

Definition of Critical Thinking

Critical thinking is an intellectual process of analyzing, evaluating, and synthesizing information to make reasoned and informed decisions.

What is Critical Thinking in Nursing?

Critical thinking in nursing is a vital cognitive skill that involves analyzing, evaluating, and making reasoned decisions about patient care.

It’s an essential aspect of a nurse’s professional practice as it enables them to provide safe and effective care to patients.

Critical thinking involves a careful and deliberate thought process to gather and assess information, consider alternative solutions, and make informed decisions based on evidence and sound judgment.

This skill helps nurses to:

• Assess Information: Critical thinking allows nurses to thoroughly assess patient information, including medical history, symptoms, and test results. By analyzing this data, nurses can identify patterns, discrepancies, and potential issues that may require further investigation.
• Diagnose: Nurses use critical thinking to analyze patient data and collaboratively work with other healthcare professionals to formulate accurate nursing diagnoses. This is crucial for developing appropriate care plans that address the unique needs of each patient.
• Plan and Implement Care: Once a nursing diagnosis is established, critical thinking helps nurses develop effective care plans. They consider various interventions and treatment options, considering the patient’s preferences, medical history, and evidence-based practices.
• Evaluate Outcomes: After implementing interventions, critical thinking enables nurses to evaluate the outcomes of their actions. If the desired outcomes are not achieved, nurses can adapt their approach and make necessary changes to the care plan.
• Prioritize Care: In busy healthcare environments, nurses often face situations where they must prioritize patient care. Critical thinking helps them determine which patients require immediate attention and which interventions are most essential.
• Communicate Effectively: Critical thinking skills allow nurses to communicate clearly and confidently with patients, their families, and other members of the healthcare team. They can explain complex medical information and treatment plans in a way that is easily understood by all parties involved.
• Identify Problems: Nurses use critical thinking to identify potential complications or problems in a patient’s condition. This early recognition can lead to timely interventions and prevent further deterioration.
• Collaborate: Healthcare is a collaborative effort involving various professionals. Critical thinking enables nurses to actively participate in interdisciplinary discussions, share their insights, and contribute to holistic patient care.
• Ethical Decision-Making: Critical thinking helps nurses navigate ethical dilemmas that can arise in patient care. They can analyze different perspectives, consider ethical principles, and make morally sound decisions.
• Continual Learning: Critical thinking encourages nurses to seek out new knowledge, stay up-to-date with the latest research and medical advancements, and incorporate evidence-based practices into their care.

In summary, critical thinking is an integral skill for nurses, allowing them to provide high-quality, patient-centered care by analyzing information, making informed decisions, and adapting their approaches as needed.

It’s a dynamic process that enhances clinical reasoning , problem-solving, and overall patient outcomes.

What are the Levels of Critical Thinking in Nursing?

The development of critical thinking in nursing practice involves progressing through three levels: basic, complex, and commitment.

The Kataoka-Yahiro and Saylor model outlines this progression.

1. Basic Critical Thinking:

At this level, learners trust experts for solutions. Thinking is based on rules and principles. For instance, nursing students may strictly follow a procedure manual without personalization, as they lack experience. Answers are seen as right or wrong, and the opinions of experts are accepted.

2. Complex Critical Thinking:

Learners start to analyze choices independently and think creatively. They recognize conflicting solutions and weigh benefits and risks. Thinking becomes innovative, with a willingness to consider various approaches in complex situations.

3. Commitment:

At this level, individuals anticipate decision points without external help and take responsibility for their choices. They choose actions or beliefs based on available alternatives, considering consequences and accountability.

As nurses gain knowledge and experience, their critical thinking evolves from relying on experts to independent analysis and decision-making, ultimately leading to committed and accountable choices in patient care.

Why Critical Thinking is Important in Nursing?

Critical thinking is important in nursing for several crucial reasons:

Patient Safety:

Nursing decisions directly impact patient well-being. Critical thinking helps nurses identify potential risks, make informed choices, and prevent errors.

Clinical Judgment:

Nursing decisions often involve evaluating information from various sources, such as patient history, lab results, and medical literature.

Critical thinking assists nurses in critically appraising this information, distinguishing credible sources, and making rational judgments that align with evidence-based practices.

Enhances Decision-Making:

In nursing, critical thinking allows nurses to gather relevant patient information, assess it objectively, and weigh different options based on evidence and analysis.

This process empowers them to make informed decisions about patient care, treatment plans, and interventions, ultimately leading to better outcomes.

Promotes Problem-Solving:

Nurses encounter complex patient issues that require effective problem-solving.

Critical thinking equips them to break down problems into manageable parts, analyze root causes, and explore creative solutions that consider the unique needs of each patient.

Drives Creativity:

Nursing care is not always straightforward. Critical thinking encourages nurses to think creatively and explore innovative approaches to challenges, especially when standard protocols might not suffice for unique patient situations.

Fosters Effective Communication:

Communication is central to nursing. Critical thinking enables nurses to clearly express their thoughts, provide logical explanations for their decisions, and engage in meaningful dialogues with patients, families, and other healthcare professionals.

Aids Learning:

Nursing is a field of continuous learning. Critical thinking encourages nurses to engage in ongoing self-directed education, seeking out new knowledge, embracing new techniques, and staying current with the latest research and developments.

Improves Relationships:

Open-mindedness and empathy are essential in nursing relationships.

Critical thinking encourages nurses to consider diverse viewpoints, understand patients’ perspectives, and communicate compassionately, leading to stronger therapeutic relationships.

Empowers Independence:

Nursing often requires autonomous decision-making. Critical thinking empowers nurses to analyze situations independently, make judgments without undue influence, and take responsibility for their actions.

Facilitates Adaptability:

Healthcare environments are ever-changing. Critical thinking equips nurses with the ability to quickly assess new information, adjust care plans, and navigate unexpected situations while maintaining patient safety and well-being.

Strengthens Critical Analysis:

In the era of vast information, nurses must discern reliable data from misinformation.

Critical thinking helps them scrutinize sources, question assumptions, and make well-founded choices based on credible information.

How to Apply Critical Thinking in Nursing? (With Examples)

Here are some examples of how nurses can apply critical thinking.

Assess Patient Data:

Critical Thinking Action: Carefully review patient history, symptoms, and test results.

Example: A nurse notices a change in a diabetic patient’s blood sugar levels. Instead of just administering insulin, the nurse considers recent dietary changes, activity levels, and possible medication interactions before adjusting the treatment plan.

Diagnose Patient Needs:

Critical Thinking Action: Analyze patient data to identify potential nursing diagnoses.

Example: After reviewing a patient’s lab results, vital signs, and observations, a nurse identifies “ Risk for Impaired Skin Integrity ” due to the patient’s limited mobility.

Plan and Implement Care:

Critical Thinking Action: Develop a care plan based on patient needs and evidence-based practices.

Example: For a patient at risk of falls, the nurse plans interventions such as hourly rounding, non-slip footwear, and bed alarms to ensure patient safety.

Evaluate Interventions:

Critical Thinking Action: Assess the effectiveness of interventions and modify the care plan as needed.

Example: After administering pain medication, the nurse evaluates its impact on the patient’s comfort level and considers adjusting the dosage or trying an alternative pain management approach.

Prioritize Care:

Critical Thinking Action: Determine the order of interventions based on patient acuity and needs.

Example: In a busy emergency department, the nurse triages patients by considering the severity of their conditions, ensuring that critical cases receive immediate attention.

Collaborate with the Healthcare Team:

Critical Thinking Action: Participate in interdisciplinary discussions and share insights.

Example: During rounds, a nurse provides input on a patient’s response to treatment, which prompts the team to adjust the care plan for better outcomes.

Ethical Decision-Making:

Critical Thinking Action: Analyze ethical dilemmas and make morally sound choices.

Example: When a terminally ill patient expresses a desire to stop treatment, the nurse engages in ethical discussions, respecting the patient’s autonomy and ensuring proper end-of-life care.

Patient Education:

Critical Thinking Action: Tailor patient education to individual needs and comprehension levels.

Example: A nurse uses visual aids and simplified language to explain medication administration to a patient with limited literacy skills.

Adapt to Changes:

Critical Thinking Action: Quickly adjust care plans when patient conditions change.

Example: During post-operative recovery, a nurse notices signs of infection and promptly informs the healthcare team to initiate appropriate treatment adjustments.

Critical Analysis of Information:

Critical Thinking Action: Evaluate information sources for reliability and relevance.

Example: When presented with conflicting research studies, a nurse critically examines the methodologies and sample sizes to determine which study is more credible.

Making Sense of Critical Thinking Skills

What is the purpose of critical thinking in nursing.

The purpose of critical thinking in nursing is to enable nurses to effectively analyze, interpret, and evaluate patient information, make informed clinical judgments, develop appropriate care plans, prioritize interventions, and adapt their approaches as needed, thereby ensuring safe, evidence-based, and patient-centered care.

Why critical thinking is important in nursing?

Critical thinking is important in nursing because it promotes safe decision-making, accurate clinical judgment, problem-solving, evidence-based practice, holistic patient care, ethical reasoning, collaboration, and adapting to dynamic healthcare environments.

Critical thinking skill also enhances patient safety, improves outcomes, and supports nurses’ professional growth.

How is critical thinking used in the nursing process?

Critical thinking is integral to the nursing process as it guides nurses through the systematic approach of assessing, diagnosing, planning, implementing, and evaluating patient care. It involves:

• Assessment: Critical thinking enables nurses to gather and interpret patient data accurately, recognizing relevant patterns and cues.
• Diagnosis: Nurses use critical thinking to analyze patient data, identify nursing diagnoses, and differentiate actual issues from potential complications.
• Planning: Critical thinking helps nurses develop tailored care plans, selecting appropriate interventions based on patient needs and evidence.
• Implementation: Nurses make informed decisions during interventions, considering patient responses and adjusting plans as needed.
• Evaluation: Critical thinking supports the assessment of patient outcomes, determining the effectiveness of intervention, and adapting care accordingly.

Throughout the nursing process , critical thinking ensures comprehensive, patient-centered care and fosters continuous improvement in clinical judgment and decision-making.

What is an example of the critical thinking attitude of independent thinking in nursing practice?

An example of the critical thinking attitude of independent thinking in nursing practice could be:

A nurse is caring for a patient with a complex medical history who is experiencing a new set of symptoms. The nurse carefully reviews the patient’s history, recent test results, and medication list.

While discussing the case with the healthcare team, the nurse realizes that the current treatment plan might not be addressing all aspects of the patient’s condition.

Instead of simply following the established protocol, the nurse independently considers alternative approaches based on their assessment.

The nurse proposes a modification to the treatment plan, citing the rationale and evidence supporting the change.

This demonstrates independent thinking by critically evaluating the situation, challenging assumptions, and advocating for a more personalized and effective patient care approach.

How to use Costa’s level of questioning for critical thinking in nursing?

Costa’s levels of questioning can be applied in nursing to facilitate critical thinking and stimulate a deeper understanding of patient situations. The levels of questioning are as follows:

• 15 Attitudes of Critical Thinking in Nursing (Explained W/ Examples)
• Nursing Concept Map (FREE Template)
• Clinical Reasoning In Nursing (Explained W/ Example)
• 8 Stages Of The Clinical Reasoning Cycle
• How To Improve Critical Thinking Skills In Nursing? 24 Strategies With Examples
• What is the “5 Whys” Technique?
• What Are Socratic Questions?

Critical thinking in nursing is the foundation that underpins safe, effective, and patient-centered care.

Critical thinking skills empower nurses to navigate the complexities of their profession while consistently providing high-quality care to diverse patient populations.

Critical Thinking in Nursing: Tips to Develop the Skill

4 min read • February, 09 2024

Critical thinking in nursing helps caregivers make decisions that lead to optimal patient care. In school, educators and clinical instructors introduced you to critical-thinking examples in nursing. These educators encouraged using learning tools for assessment, diagnosis, planning, implementation, and evaluation.

Nurturing these invaluable skills continues once you begin practicing. Critical thinking is essential to providing quality patient care and should continue to grow throughout your nursing career until it becomes second nature. 

What Is Critical Thinking in Nursing?

Critical thinking in nursing involves identifying a problem, determining the best solution, and implementing an effective method to resolve the issue using clinical decision-making skills.

Reflection comes next. Carefully consider whether your actions led to the right solution or if there may have been a better course of action.

Remember, there's no one-size-fits-all treatment method — you must determine what's best for each patient.

How Is Critical Thinking Important for Nurses? 

As a patient's primary contact, a nurse is typically the first to notice changes in their status. One example of critical thinking in nursing is interpreting these changes with an open mind. Make impartial decisions based on evidence rather than opinions. By applying critical-thinking skills to anticipate and understand your patients' needs, you can positively impact their quality of care and outcomes.

Elements of Critical Thinking in Nursing

To assess situations and make informed decisions, nurses must integrate these specific elements into their practice:

• Clinical judgment. Prioritize a patient's care needs and make adjustments as changes occur. Gather the necessary information and determine what nursing intervention is needed. Keep in mind that there may be multiple options. Use your critical-thinking skills to interpret and understand the importance of test results and the patient’s clinical presentation, including their vital signs. Then prioritize interventions and anticipate potential complications. 
• Patient safety. Recognize deviations from the norm and take action to prevent harm to the patient. Suppose you don't think a change in a patient's medication is appropriate for their treatment. Before giving the medication, question the physician's rationale for the modification to avoid a potential error. 
• Communication and collaboration. Ask relevant questions and actively listen to others while avoiding judgment. Promoting a collaborative environment may lead to improved patient outcomes and interdisciplinary communication. 
• Problem-solving skills. Practicing your problem-solving skills can improve your critical-thinking skills. Analyze the problem, consider alternate solutions, and implement the most appropriate one. Besides assessing patient conditions, you can apply these skills to other challenges, such as staffing issues . 

How to Develop and Apply Critical-Thinking Skills in Nursing

Critical-thinking skills develop as you gain experience and advance in your career. The ability to predict and respond to nursing challenges increases as you expand your knowledge and encounter real-life patient care scenarios outside of what you learned from a textbook. 

Here are five ways to nurture your critical-thinking skills:

• Be a lifelong learner. Continuous learning through educational courses and professional development lets you stay current with evidence-based practice . That knowledge helps you make informed decisions in stressful moments.  
• Practice reflection. Allow time each day to reflect on successes and areas for improvement. This self-awareness can help identify your strengths, weaknesses, and personal biases to guide your decision-making.
• Open your mind. Don't assume you're right. Ask for opinions and consider the viewpoints of other nurses, mentors , and interdisciplinary team members.
• Use critical-thinking tools. Structure your thinking by incorporating nursing process steps or a SWOT analysis (strengths, weaknesses, opportunities, and threats) to organize information, evaluate options, and identify underlying issues.
• Be curious. Challenge assumptions by asking questions to ensure current care methods are valid, relevant, and supported by evidence-based practice .

Critical thinking in nursing is invaluable for safe, effective, patient-centered care. You can successfully navigate challenges in the ever-changing health care environment by continually developing and applying these skills.

The Concept of Advocacy in Nursing

A critical analysis.

Kalaitzidis, Evdokia PhD; Jewell, Paul PhD

As health care professionals practice as a team, they take on responsibilities that are specific to their roles—responsibilities that are recognized and understood by the team and management as pertaining to their professional domain and expertise. Is advocacy part of the role of the nurse? Members of the nursing profession commonly maintain that it is, but is there a consensus on this issue, both within the profession and among other stakeholders? Is there a clear understanding of the term advocacy , and is this reflected in Codes of Practice and research into practice? An examination of significant documents and reports of empirical research reveals conflicting conceptions and opinions. There is potential for a common definition, but agreements need to be reached on whether advocacy is an essential function of nursing within the management of health care, and if so, what is advocacy’s importance, focus, and limits.

Evidence-based practice is the integration of individual clinical expertise with the best available external clinical evidence from systematic research and patient’s values and expectations into the decision making process for patient care. It is a fundamental skill to be able to identify and appraise the best available evidence in order to integrate it with your own clinical experience and patients values. The aim of this article is to provide a robust and simple process for assessing the credibility of articles and their value to your clinical practice.

Introduction

Decisions related to patient value and care is carefully made following an essential process of integration of the best existing evidence, clinical experience and patient preference. Critical appraisal is the course of action for watchfully and systematically examining research to assess its reliability, value and relevance in order to direct professionals in their vital clinical decision making [ 1 ].

Critical appraisal is essential to:

• Combat information overload;
• Identify papers that are clinically relevant;
• Continuing Professional Development (CPD).

Carrying out Critical Appraisal:

Assessing the research methods used in the study is a prime step in its critical appraisal. This is done using checklists which are specific to the study design.

Standard Common Questions:

• What is the research question?
• What is the study type (design)?
• Selection issues.
• What are the outcome factors and how are they measured?
• What are the study factors and how are they measured?
• What important potential confounders are considered?
• What is the statistical method used in the study?
• Statistical results.
• What conclusions did the authors reach about the research question?
• Are ethical issues considered?

The Critical Appraisal starts by double checking the following main sections:

I. Overview of the paper:

• The publishing journal and the year
• The article title: Does it state key trial objectives?
• The author (s) and their institution (s)

The presence of a peer review process in journal acceptance protocols also adds robustness to the assessment criteria for research papers and hence would indicate a reduced likelihood of publication of poor quality research. Other areas to consider may include authors’ declarations of interest and potential market bias. Attention should be paid to any declared funding or the issue of a research grant, in order to check for a conflict of interest [ 2 ].

II. ABSTRACT: Reading the abstract is a quick way of getting to know the article and its purpose, major procedures and methods, main findings, and conclusions.

• Aim of the study: It should be well and clearly written.
• Materials and Methods: The study design and type of groups, type of randomization process, sample size, gender, age, and procedure rendered to each group and measuring tool(s) should be evidently mentioned.
• Results: The measured variables with their statistical analysis and significance.
• Conclusion: It must clearly answer the question of interest.

III. Introduction/Background section:

An excellent introduction will thoroughly include references to earlier work related to the area under discussion and express the importance and limitations of what is previously acknowledged [ 2 ].

-Why this study is considered necessary? What is the purpose of this study? Was the purpose identified before the study or a chance result revealed as part of ‘data searching?’

-What has been already achieved and how does this study be at variance?

-Does the scientific approach outline the advantages along with possible drawbacks associated with the intervention or observations?

IV. Methods and Materials section : Full details on how the study was actually carried out should be mentioned. Precise information is given on the study design, the population, the sample size and the interventions presented. All measurements approaches should be clearly stated [ 3 ].

V. Results section : This section should clearly reveal what actually occur to the subjects. The results might contain raw data and explain the statistical analysis. These can be shown in related tables, diagrams and graphs.

VI. Discussion section : This section should include an absolute comparison of what is already identified in the topic of interest and the clinical relevance of what has been newly established. A discussion on a possible related limitations and necessitation for further studies should also be indicated.

Does it summarize the main findings of the study and relate them to any deficiencies in the study design or problems in the conduct of the study? (This is called intention to treat analysis).

• Does it address any source of potential bias?
• Are interpretations consistent with the results?
• How are null findings interpreted?
• Does it mention how do the findings of this study relate to previous work in the area?
• Can they be generalized (external validity)?
• Does it mention their clinical implications/applicability?
• What are the results/outcomes/findings applicable to and will they affect a clinical practice?
• Does the conclusion answer the study question?
• -Is the conclusion convincing?
• -Does the paper indicate ethics approval?
• -Can you identify potential ethical issues?
• -Do the results apply to the population in which you are interested?
• -Will you use the results of the study?

Once you have answered the preliminary and key questions and identified the research method used, you can incorporate specific questions related to each method into your appraisal process or checklist.

1-What is the research question?

For a study to gain value, it should address a significant problem within the healthcare and provide new or meaningful results. Useful structure for assessing the problem addressed in the article is the Problem Intervention Comparison Outcome (PICO) method [ 3 ].

P = Patient or problem: Patient/Problem/Population:

It involves identifying if the research has a focused question. What is the chief complaint?

E.g.,: Disease status, previous ailments, current medications etc.,

I = Intervention: Appropriately and clearly stated management strategy e.g.,: new diagnostic test, treatment, adjunctive therapy etc.,

C= Comparison: A suitable control or alternative

E.g.,: specific and limited to one alternative choice.

O= Outcomes: The desired results or patient related consequences have to be identified. e.g.,: eliminating symptoms, improving function, esthetics etc.,

The clinical question determines which study designs are appropriate. There are five broad categories of clinical questions, as shown in [ Table/Fig-1 ].

[Table/Fig-1]:

Categories of clinical questions and the related study designs.

2- What is the study type (design)?

The study design of the research is fundamental to the usefulness of the study.

In a clinical paper the methodology employed to generate the results is fully explained. In general, all questions about the related clinical query, the study design, the subjects and the correlated measures to reduce bias and confounding should be adequately and thoroughly explored and answered.

Participants/Sample Population:

Researchers identify the target population they are interested in. A sample population is therefore taken and results from this sample are then generalized to the target population.

The sample should be representative of the target population from which it came. Knowing the baseline characteristics of the sample population is important because this allows researchers to see how closely the subjects match their own patients [ 4 ].

Sample size calculation (Power calculation): A trial should be large enough to have a high chance of detecting a worthwhile effect if it exists. Statisticians can work out before the trial begins how large the sample size should be in order to have a good chance of detecting a true difference between the intervention and control groups [ 5 ].

• Is the sample defined? Human, Animals (type); what population does it represent?
• Does it mention eligibility criteria with reasons?
• Does it mention where and how the sample were recruited, selected and assessed?
• Does it mention where was the study carried out?
• Is the sample size justified? Rightly calculated? Is it adequate to detect statistical and clinical significant results?
• Does it mention a suitable study design/type?
• Is the study type appropriate to the research question?
• Is the study adequately controlled? Does it mention type of randomization process? Does it mention the presence of control group or explain lack of it?
• Are the samples similar at baseline? Is sample attrition mentioned?
• All studies report the number of participants/specimens at the start of a study, together with details of how many of them completed the study and reasons for incomplete follow up if there is any.
• Does it mention who was blinded? Are the assessors and participants blind to the interventions received?
• Is it mentioned how was the data analysed?
• Are any measurements taken likely to be valid?

Researchers use measuring techniques and instruments that have been shown to be valid and reliable.

Validity refers to the extent to which a test measures what it is supposed to measure.

(the extent to which the value obtained represents the object of interest.)

• -Soundness, effectiveness of the measuring instrument;
• -What does the test measure?
• -Does it measure, what it is supposed to be measured?
• -How well, how accurately does it measure?

Reliability: In research, the term reliability means “repeatability” or “consistency”

Reliability refers to how consistent a test is on repeated measurements. It is important especially if assessments are made on different occasions and or by different examiners. Studies should state the method for assessing the reliability of any measurements taken and what the intra –examiner reliability was [ 6 ].

3-Selection issues:

The following questions should be raised:

• - How were subjects chosen or recruited? If not random, are they representative of the population?
• - Types of Blinding (Masking) Single, Double, Triple?
• - Is there a control group? How was it chosen?
• - How are patients followed up? Who are the dropouts? Why and how many are there?
• - Are the independent (predictor) and dependent (outcome) variables in the study clearly identified, defined, and measured?
• - Is there a statement about sample size issues or statistical power (especially important in negative studies)?
• - If a multicenter study, what quality assurance measures were employed to obtain consistency across sites?
• - Are there selection biases?
• • In a case-control study, if exercise habits to be compared:
• - Are the controls appropriate?
• - Were records of cases and controls reviewed blindly?
• - How were possible selection biases controlled (Prevalence bias, Admission Rate bias, Volunteer bias, Recall bias, Lead Time bias, Detection bias, etc.,)?
• • Cross Sectional Studies:
• - Was the sample selected in an appropriate manner (random, convenience, etc.,)?
• - Were efforts made to ensure a good response rate or to minimize the occurrence of missing data?
• - Were reliability (reproducibility) and validity reported?
• • In an intervention study, how were subjects recruited and assigned to groups?
• • In a cohort study, how many reached final follow-up?
• - Are the subject’s representatives of the population to which the findings are applied?
• - Is there evidence of volunteer bias? Was there adequate follow-up time?
• - What was the drop-out rate?
• - Any shortcoming in the methodology can lead to results that do not reflect the truth. If clinical practice is changed on the basis of these results, patients could be harmed.

Researchers employ a variety of techniques to make the methodology more robust, such as matching, restriction, randomization, and blinding [ 7 ].

Bias is the term used to describe an error at any stage of the study that was not due to chance. Bias leads to results in which there are a systematic deviation from the truth. As bias cannot be measured, researchers need to rely on good research design to minimize bias [ 8 ]. To minimize any bias within a study the sample population should be representative of the population. It is also imperative to consider the sample size in the study and identify if the study is adequately powered to produce statistically significant results, i.e., p-values quoted are <0.05 [ 9 ].

4-What are the outcome factors and how are they measured?

• -Are all relevant outcomes assessed?
• -Is measurement error an important source of bias?

5-What are the study factors and how are they measured?

• -Are all the relevant study factors included in the study?
• -Have the factors been measured using appropriate tools?

Data Analysis and Results:

- Were the tests appropriate for the data?

- Are confidence intervals or p-values given?

• How strong is the association between intervention and outcome?
• How precise is the estimate of the risk?
• Does it clearly mention the main finding(s) and does the data support them?
• Does it mention the clinical significance of the result?
• Is adverse event or lack of it mentioned?
• Are all relevant outcomes assessed?
• Was the sample size adequate to detect a clinically/socially significant result?
• Are the results presented in a way to help in health policy decisions?
• Is there measurement error?
• Is measurement error an important source of bias?

Confounding Factors:

A confounder has a triangular relationship with both the exposure and the outcome. However, it is not on the causal pathway. It makes it appear as if there is a direct relationship between the exposure and the outcome or it might even mask an association that would otherwise have been present [ 9 ].

6- What important potential confounders are considered?

• -Are potential confounders examined and controlled for?
• -Is confounding an important source of bias?

7- What is the statistical method in the study?

• -Are the statistical methods described appropriate to compare participants for primary and secondary outcomes?
• -Are statistical methods specified insufficient detail (If I had access to the raw data, could I reproduce the analysis)?
• -Were the tests appropriate for the data?
• -Are confidence intervals or p-values given?
• -Are results presented as absolute risk reduction as well as relative risk reduction?

Interpretation of p-value:

The p-value refers to the probability that any particular outcome would have arisen by chance. A p-value of less than 1 in 20 (p<0.05) is statistically significant.

• When p-value is less than significance level, which is usually 0.05, we often reject the null hypothesis and the result is considered to be statistically significant. Conversely, when p-value is greater than 0.05, we conclude that the result is not statistically significant and the null hypothesis is accepted.

Confidence interval:

Multiple repetition of the same trial would not yield the exact same results every time. However, on average the results would be within a certain range. A 95% confidence interval means that there is a 95% chance that the true size of effect will lie within this range.

8- Statistical results:

• -Do statistical tests answer the research question?

Are statistical tests performed and comparisons made (data searching)?

Correct statistical analysis of results is crucial to the reliability of the conclusions drawn from the research paper. Depending on the study design and sample selection method employed, observational or inferential statistical analysis may be carried out on the results of the study.

It is important to identify if this is appropriate for the study [ 9 ].

• -Was the sample size adequate to detect a clinically/socially significant result?
• -Are the results presented in a way to help in health policy decisions?

Clinical significance:

Statistical significance as shown by p-value is not the same as clinical significance. Statistical significance judges whether treatment effects are explicable as chance findings, whereas clinical significance assesses whether treatment effects are worthwhile in real life. Small improvements that are statistically significant might not result in any meaningful improvement clinically. The following questions should always be on mind:

• -If the results are statistically significant, do they also have clinical significance?
• -If the results are not statistically significant, was the sample size sufficiently large to detect a meaningful difference or effect?

9- What conclusions did the authors reach about the study question?

Conclusions should ensure that recommendations stated are suitable for the results attained within the capacity of the study. The authors should also concentrate on the limitations in the study and their effects on the outcomes and the proposed suggestions for future studies [ 10 ].

• -Are the questions posed in the study adequately addressed?
• -Are the conclusions justified by the data?
• -Do the authors extrapolate beyond the data?
• -Are shortcomings of the study addressed and constructive suggestions given for future research?
• -Bibliography/References:

Do the citations follow one of the Council of Biological Editors’ (CBE) standard formats?

10- Are ethical issues considered?

If a study involves human subjects, human tissues, or animals, was approval from appropriate institutional or governmental entities obtained? [ 10 , 11 ].

Critical appraisal of RCTs: Factors to look for:

• Allocation (randomization, stratification, confounders).
• Follow up of participants (intention to treat).
• Data collection (bias).
• Sample size (power calculation).
• Presentation of results (clear, precise).
• Applicability to local population.

Critical appraisal of systematic reviews: provide an overview of all primary studies on a topic and try to obtain an overall picture of the results.

In a systematic review, all the primary studies identified are critically appraised and only the best ones are selected. A meta-analysis (i.e., a statistical analysis) of the results from selected studies may be included. Factors to look for:

• Literature search (did it include published and unpublished materials as well as non-English language studies? Was personal contact with experts sought?).
• Quality-control of studies included (type of study; scoring system used to rate studies; analysis performed by at least two experts).
• Homogeneity of studies.

Critical appraisal is a fundamental skill in modern practice for assessing the value of clinical researches and providing an indication of their relevance to the profession. It is a skills-set developed throughout a professional career that facilitates this and, through integration with clinical experience and patient preference, permits the practice of evidence based medicine and dentistry. By following a systematic approach, such evidence can be considered and applied to clinical practice.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.

The Concept of Advocacy in Nursing: A Critical Analysis

As health care professionals practice as a team, they take on responsibilities that are specific to their roles-responsibilities that are recognized and understood by the team and management as pertaining to their professional domain and expertise. Is advocacy part of the role of the nurse? Members of the nursing profession commonly maintain that it is, but is there a consensus on this issue, both within the profession and among other stakeholders? Is there a clear understanding of the term advocacy, and is this reflected in Codes of Practice and research into practice? An examination of significant documents and reports of empirical research reveals conflicting conceptions and opinions. There is potential for a common definition, but agreements need to be reached on whether advocacy is an essential function of nursing within the management of health care, and if so, what is advocacy's importance, focus, and limits.
