NCLEX Critical Thinking Strategies

The NCLEX isn’t a knowledge test. That surprises a lot of nursing graduates who studied hard, know their content, and still struggle with practice questions. The exam tests clinical judgment—your ability to think through a patient scenario and make the safest decision. Here’s how to build that skill.

Why Is the NCLEX Different from Nursing School Exams?

In school, you’re often tested on recall: What’s the normal range for sodium? What are the signs of heart failure? The NCLEX assumes you know those basics and asks you to do something with them.

School Exam	NCLEX
”What is the normal potassium range?"	"Which patient should the nurse see first?” (one has K+ of 6.2)
“List the signs of digoxin toxicity"	"The patient on digoxin reports nausea and sees yellow halos. What should the nurse do first?"
"Describe the stages of pressure injuries"	"A patient has a Stage 2 pressure injury. Which nursing intervention is most appropriate?”

The shift is from knowing to deciding. And deciding under pressure, with incomplete information, where multiple answers sound reasonable—that’s critical thinking.

What Frameworks Help with Priority Questions?

Priority questions (“Which patient should the nurse see first?” “What is the nurse’s priority action?”) are the NCLEX’s bread and butter. These frameworks help you think through them systematically.

ABCs (Airway, Breathing, Circulation)

The most fundamental priority framework.

Priority	Examples
Airway (highest)	Obstruction, stridor, edema, inability to maintain airway
Breathing	Respiratory distress, low O2 sat, abnormal breath sounds
Circulation	Hemorrhage, chest pain, arrhythmias, shock signs

When two answer choices both seem urgent, the one involving airway trumps breathing, and breathing trumps circulation. But be careful—a patient who’s alert and talking has an intact airway, so don’t always pick the airway answer by default.

Maslow’s Hierarchy of Needs

Level	Nursing Priority	Example
Physiological (highest)	Oxygenation, nutrition, fluids, elimination, pain	A patient who can’t breathe
Safety	Fall prevention, infection control, medication safety	A confused patient trying to climb out of bed
Love/belonging	Emotional support, family involvement	A patient feeling isolated
Esteem	Independence, dignity, patient teaching	A patient frustrated about self-care limitations
Self-actualization (lowest)	Setting goals, patient empowerment	A patient planning life after discharge

Physiological needs take priority over psychosocial ones. If one answer addresses physical safety and another addresses emotional comfort, go with physical safety.

Nursing Process

Step	When It’s the Answer
Assessment	When you need more information before acting
Diagnosis	Rarely tested directly
Planning	When establishing goals or care plans
Implementation	When you have enough information to act
Evaluation	When checking if an intervention worked

The key rule: assess before you intervene—unless the patient is in immediate danger. If a question gives you an unexpected lab value, your first action is usually to reassess the patient or verify the result, not to call the provider or give medication.

The exception: If the patient is coding, seizing, or actively deteriorating, skip assessment and intervene.

How Do You Use Process of Elimination Effectively?

Step 1: Read the Question Stem Carefully

What is it actually asking? Common NCLEX stems:

Stem	What They Want
”What should the nurse do first?”	Priority action
”Which finding requires immediate follow-up?”	Identify the abnormal/dangerous value
”Which patient should the nurse see first?”	Triage priority
”Which statement indicates understanding?”	Correct patient teaching
”Which response by the nurse is most therapeutic?”	Communication technique

Step 2: Eliminate Obviously Wrong Answers

Usually at least one answer is clearly incorrect. Look for:

Red Flag	Example
Unsafe actions	”Administer the medication as ordered” when the scenario implies a contraindication
Non-nursing actions	”Call the chaplain” when the patient has a physiological problem
Premature interventions	”Administer epinephrine” before assessing the patient
Documentation as first action	”Document the finding” is almost never the first priority
Absolutes	”Always,” “never,” “only”—these are usually wrong

Step 3: Compare Remaining Options

When two answers both seem correct (this happens a lot), ask:

1. Which is more immediate? A deteriorating patient takes priority over a stable one.
2. Which addresses the root cause? Treating the cause beats treating a symptom.
3. Which is within nursing scope? Nurses assess and intervene; physicians diagnose and prescribe.
4. Which follows the nursing process? Assess before intervening, unless there’s immediate danger.

How Do You Handle Specific Question Types?

SATA (Select All That Apply)

These NGN-style questions are feared, but they follow logic.

Strategy	Details
Treat each option independently	Ask “Is this correct?” for each choice separately
Don’t look for patterns	There’s no required minimum or maximum number of correct answers
Partial credit exists	On the new NGN format, you can get partial credit
Read carefully	One word can change whether an option is correct

Delegation Questions

Person	Can Do	Cannot Do
RN	Assessment, teaching, care planning, IV meds, blood products	—
LPN/LVN	Stable patients, routine meds, wound care, data collection	Initial assessment, teaching, unstable patients
UAP/CNA	Vital signs, bathing, feeding, ambulation, I&O	Any nursing judgment, medication administration, assessment

The rule: delegate tasks, not nursing judgment. Anything requiring assessment, evaluation, or clinical decision-making stays with the RN.

Therapeutic Communication

Therapeutic	Non-therapeutic
”Tell me more about that"	"Don’t worry, everything will be fine"
"It sounds like you’re feeling…"	"I know exactly how you feel"
"What concerns you most?"	"Why did you do that?”
Open-ended questions	Yes/no questions
Reflecting feelings	Giving advice or opinions

When in doubt, pick the answer that acknowledges the patient’s feelings and encourages them to keep talking.

How Do You Build Critical Thinking Before Test Day?

Practice with Purpose

Approach	Why It Works
Do 50-75 questions daily	Builds pattern recognition
Read ALL rationales	Even for correct answers—understand why the others are wrong
Track error patterns	Are you rushing? Misreading stems? Picking second-best answers?
Practice under timed conditions	The real exam has time pressure
Use multiple question banks	Each source has different question styles

Check our NCLEX prep resources and study plan guides for structured approaches.

Common Critical Thinking Traps

Trap	Example	Fix
Reading into the question	Adding information that isn’t in the stem	Only use what’s given
Picking the “real world” answer	”In my clinical, we did X”	Answer based on textbook best practice
Changing your answer	Second-guessing after selecting	Stick with your first instinct unless you misread
Anchoring on one detail	Fixating on a lab value and ignoring the clinical picture	Consider the whole scenario
Overthinking	”But what if the patient also has…”	The question gives you everything you need

A Practical Example

Question: A nurse is caring for four patients. Which patient should the nurse assess first?

A. Patient with diabetes who has a blood glucose of 210 mg/dL B. Patient post-appendectomy who reports pain of 6/10 C. Patient with COPD who has an O2 saturation of 88% D. Patient with a urinary catheter who had 200 mL output in the past 8 hours

Think through it:

• A: Glucose of 210 is elevated but not critically dangerous. Can wait.
• B: Pain of 6/10 post-surgery is expected. Manage, but not first.
• C: O2 sat of 88% in a COPD patient—near their baseline (COPD patients often run 88-92%). Not necessarily acute.
• D: 200 mL in 8 hours is only 25 mL/hour—below the 30 mL/hour minimum. Could signal renal failure or obstruction.

Did you default to C because of ABCs? That’s the trap. A COPD patient at 88% may be stable. A patient producing only 25 mL/hour of urine could be heading toward kidney failure. The answer is D. Frameworks give you a starting point, but clinical judgment gives you the right answer.

One Final Thought

Critical thinking isn’t something you either have or don’t. It’s a skill that develops with practice. Every practice question you do, every rationale you read, every “but why?” you ask yourself—it all builds the pattern recognition that makes the NCLEX manageable. Trust the process, and don’t expect perfection. The exam doesn’t require perfection either.
