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

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.
