Critical thinking Purposeful, reflective reasoning about what to believe and do Full entry → in nursing is purposeful, reflective reasoning about what to believe and what to do in patient care. It is not the same as being intelligent, having a good memory, or "knowing your stuff" — it is a set of skills and habits you can deliberately build: asking questions, examining assumptions, seeking evidence, considering alternatives, and checking your own conclusions. In this chapter, critical thinking is the how behind the Clinical Judgment Measurement Model: the CJMM names the steps of Clinical reasoning The thinking process that leads to a clinical conclusion or action Full entry →, and critical thinking supplies the skill and the attitude to perform those steps well.
A common myth is that critical thinkers are born, not made. In reality, the skill develops through practice, feedback, and reflection. Students and new graduates who improve fastest are usually not the ones with the most facts; they are the ones who routinely ask "what else could this be?" and "why am I confident in this answer?"
Why this matters
- Errors are often thinking errors. Many patient-safety events trace back to a reasoning failure — anchoring on the first explanation, closing the search too early, or ignoring a cue that didn't fit the story — not to a knowledge gap.
- Nurses make independent decisions. Within their scope, nurses continuously decide what to assess, what to report, what to prioritize, and how to respond. Those decisions deserve deliberate reasoning.
- Accountability. Nurses are accountable for their judgments, and a chart or a handoff reflects the thinking behind them.
- Teamwork. Handoffs, rapid responses, and everyday communication improve when every member can explain why they think what they think — not just what they observed.

Core Concepts
What critical thinking means in nursing
The American Philosophical Association's Delphi study described critical thinking as "purposeful, self-regulatory judgment." In nursing, that means reasoning that is purposeful (aimed at a care decision), evidence-based (grounded in assessment data and reliable sources), and self-correcting (you revisit conclusions when new information arrives) — happening both at the bedside and in reflection afterward.
Core thinking skills
Educators commonly organize critical thinking into six overlapping skills:
- Interpretation — understanding and stating what data mean ("the patient reports pain that is worse than this morning").
- Analysis — examining the relationships between pieces of information and between claims and their evidence.
- Inference A conclusion drawn from evidence, held as tentative Full entry → — drawing reasonable conclusions from the available data while recognizing they are tentative.
- Evaluation — judging the credibility of information and the strength of an argument ("is this family member's report consistent with what I can observe?").
- Explanation — stating your reasoning clearly so others can follow and check it.
- Self-regulation Monitoring and correcting your own thinking Full entry → — monitoring your own thinking, admitting when you were wrong, and adjusting course.
Thinking dispositions (habits of mind)
Skills matter, but so do attitudes. Dispositions such as open-mindedness (willingness to consider explanations that are not yours), intellectual humility (knowing what you do not know), fair-mindedness (weighing evidence even when it is inconvenient), curiosity, and perseverance separate strong clinical thinkers from merely clever ones. A student who can list every assessment technique but "already knows" the answer before looking is not thinking critically.
Questioning as a clinical tool
Questioning is the engine of critical thinking. Useful clinical questions: "What is this patient's baseline, and how does today compare?" "What else could explain these findings?" "What information is missing?" "What would change my mind?" "Urgent problem or can-wait problem?" Questioning also applies to orders: a nurse who notices an order inconsistent with the patient's situation asks a clarifying question rather than assuming — expected professional behavior, not insubordination.
Reflection: in action and on action
Reflection happens two ways. Reflection-in-action is thinking while you work — adjusting your assessment as the patient's response unfolds. Reflection-on-action Reviewing your reasoning after an event to learn from it Full entry → is thinking after the event: What did I assume? Where did my reasoning go well? What would I do differently? Structured tools — debriefing after simulation, clinical journals, concept maps, and post-shift "one thing I learned" habits — turn experience into learning.
Common thinking traps
Knowing your cognitive biases is part of the skill. Common traps in nursing include anchoring (fixing on the first explanation), confirmation bias (noticing only data that support your hypothesis), the availability heuristic (overweighting the most recent or most memorable explanation), and Premature closure Stopping the search for explanations once you have one that fits Full entry → (stopping the search once you have an answer that feels right). System factors — fatigue, time pressure, distractions, and deference to hierarchy — make these traps more likely, which is why safe organizations build in second checks, huddles, and a culture where anyone can speak up.
Deliberate practice
Critical thinking improves with deliberate practice: working through varied patient scenarios, explaining your reasoning out loud, comparing your reasoning with an expert's, and seeking specific feedback. Concept maps and SBAR (Situation, Background, Assessment, Recommendation) are scaffolds that force you to organize and justify your thinking before communicating.
Common Confusions
| Do not confuse | With | Difference |
|---|---|---|
| Critical thinking | Clinical judgment | Critical thinking is the general reasoning skill; clinical judgment is that skill applied to a specific patient decision |
| Being skeptical | Being difficult | Questioning is expected and professional when it is aimed at safety and backed by evidence |
| Intuition | Guessing | Experienced "clinical intuition" is pattern recognition built from past cases; guessing skips the evidence |
| A quick decision | A hasty decision | Fast reasoning can be sound when built on experience and a mental checklist; hasty reasoning skips the checks |
| Knowledge | Thinking skill | Facts are necessary but do not guarantee good reasoning — you still have to question and evaluate |
| Speaking up | Challenging authority | Raising a concern respectfully about an order or finding is standard practice, not insubordination |
Eli explains
The same idea, in plain words
Explain it like I’m 10
Critical thinking is like being a detective AND a scientist at the same time. A detective gathers clues and asks "what else could this mean?" instead of jumping to the first answer. A scientist tests ideas and changes their mind when new evidence shows up. Nurses practice this every day: they look at the clues, ask good questions, check their guesses, and are honest when they are not sure.
Worked example
Educational illustration — medication administration always follows the provider's order, facility policy, and the nurse's scope of practice.
A nurse is preparing to give a medication that is unfamiliar. The easy path is to scan the label and give it. The critical-thinking path looks like this:
- Question: "Why is this patient receiving this, and why now?" The nurse reads the order, checks the patient's identity and the medication against the order, and reviews the patient's recent condition and allergies.
- Seek evidence: The nurse looks up the medication in the facility's approved drug reference, noting the expected indication and what to observe after giving it — not memorized guesses.
- Notice a mismatch: The dose on the label does not match the order as written. Instead of assuming a typo, the nurse stops.
- Act on the question: The nurse holds the medication, contacts the pharmacist and the provider for clarification, and documents the question per policy — the exact behavior expected of a safe nurse.
- Reflect: Afterward, the nurse notes the lesson ("always compare the label to the order line by line") in a learning log.
The reasoning skills here are the same ones tested in a case study: interpret the order, analyze the mismatch, evaluate the risk, explain the concern, and self-regulate by pausing rather than proceeding. (This scenario illustrates reasoning, not a specific medication or dose; all administration details follow the order, the reference, and facility policy.)
Key takeaways
- Critical thinking is purposeful, evidence-based, and self-correcting — not the same as intelligence or knowledge.
- Six core skills: interpretation, analysis, inference, evaluation, explanation, and self-regulation.
- Dispositions (open-mindedness, intellectual humility, curiosity) matter as much as skills.
- Questioning — including questioning orders respectfully — is an expected professional behavior.
- Reflect both in action (while working) and on action (afterward).
- Anchor on the wrong thing, confirm your own bias, or close too early — these are the classic reasoning traps on exams and at the bedside.
- Practice deliberately: varied cases, out-loud reasoning, feedback, concept maps, and SBAR.

What are the six core critical-thinking skills commonly taught in nursing education?
Show answer
Interpretation, analysis, inference, evaluation, explanation, and self-regulation.
Give one example of a Cognitive bias A systematic error in thinking, such as anchoring or confirmation bias Full entry → and how it could distort a nurse's reasoning.
Show answer
Anchoring: fixating on the first explanation offered (for example, the handoff report's impression) so that later, contradictory cues are downplayed or missed. Confirmation bias, availability heuristic, and premature closure are other examples.
Why is self-regulation considered part of critical thinking rather than a separate personality trait?
Show answer
Because thinking critically includes monitoring and correcting your own reasoning — admitting a hypothesis is wrong, seeking disconfirming evidence, and changing course. Without self-regulation, the other skills can be used to defend a mistake.
How does reflection-on-action differ from reflection-in-action?
Show answer
Reflection-in-action happens while you are working (adjusting as the patient responds); reflection-on-action happens afterward (reviewing assumptions and decisions to learn for next time).
What makes a question "clinical" rather than just curious?
Show answer
A clinical question is aimed at a care decision, is answerable with assessment data and reliable sources, and changes what you do — for example, "what is this patient's baseline, and how does today compare?" rather than a purely hypothetical question.
