NCLEX Priority Questions: How to Use ABCs, Maslow, and Clinical Judgment to Choose Correctly

Priority questions are among the most challenging on the NCLEX — and among the most common. Nearly every question on the exam has a prioritization element, whether it's "which client do you see first," "what is your priority intervention," or "which finding requires immediate action." Mastering NCLEX priority questions requires a systematic framework, not guesswork. This guide teaches you exactly how to think through these questions every time.

The ABCs: Your First Priority Framework

The ABCs — Airway, Breathing, Circulation — form the foundation of all clinical prioritization. In any emergency or triage scenario, this hierarchy determines which problem demands attention first:

1. Airway: Is the airway patent? Obstruction is immediately life-threatening. Interventions include positioning, suctioning, or emergency airway management.
2. Breathing: Is the patient breathing adequately? Assess rate, depth, effort, and oxygen saturation. Respiratory distress takes priority over non-respiratory issues.
3. Circulation: Is perfusion adequate? Signs of shock (hypotension, tachycardia, pallor, diaphoresis) require urgent intervention.

Key rule: Always address the highest level of the ABC hierarchy first. A patient with both a low SpO2 and a low BP — the SpO2 (breathing) is addressed before the BP (circulation) unless hemorrhage is the root cause.

Maslow's Hierarchy of Needs

When no ABC issue exists, apply Maslow's Hierarchy. Physiological needs always take priority over psychological or social needs:

1. Physiological: Oxygen, nutrition, fluid, elimination, temperature, shelter — basic survival needs.
2. Safety and Security: Physical safety, prevention of falls, infection control, environmental hazards.
3. Love and Belonging: Social support, family connection, belonging to a community.
4. Esteem: Dignity, self-worth, achievement.
5. Self-Actualization: Reaching one's full potential.

NCLEX application: A patient who is anxious about surgery (psychosocial) is a lower priority than a patient with a blood glucose of 42 mg/dL (physiological). Address the physiological need first, then return to psychosocial concerns.

Stable vs. Unstable: The Critical Distinction

Many priority questions ask you to identify which client is most unstable or needs to be seen first. The key is distinguishing expected findings from unexpected or deteriorating findings:

• Stable: Vital signs within expected range for the client's condition; findings consistent with their diagnosis; no acute changes.
• Unstable: Sudden change in condition, vital sign deterioration, unexpected findings, or signs of a complication.

A post-op day 2 patient with mild incisional pain is stable. A post-op day 2 patient with sudden onset chest pain and SpO2 of 88% is unstable — see them first, immediately.

Tip: The word "sudden" in an answer option often signals instability. Sudden changes are almost always higher priority than gradual ones.

Delegation Rules: What the RN Can and Cannot Delegate

Delegation questions are a major priority category. The NCLEX tests your knowledge of the RN scope versus unlicensed assistive personnel (UAP) and licensed practical/vocational nurses (LPN/LVN).

RN Must Retain (Cannot Delegate)

• Initial assessment and reassessment of unstable patients
• Developing or updating the nursing care plan
• Client teaching and health education
• Administering IV push medications
• Interpreting and acting on clinical data
• Complex wound care or procedures requiring nursing judgment

What LPN/LVN Can Do

• Routine assessments on stable patients
• Administer oral, IM, and subcutaneous medications
• Perform wound care and dressing changes on stable wounds
• Monitor and report changes (but RN acts on findings)
• Insert urinary catheters and NGTs in some states

What UAP (CNA/Tech) Can Do

• Vital signs on stable patients
• Activities of daily living (bathing, feeding, ambulation)
• Intake and output measurement
• Specimen collection (urine, stool)
• Repositioning and skin care

5 Priority Scenarios with Answers

Scenario 1: Which patient do you assess first?

You have 4 patients: (A) Post-op cholecystectomy day 1, reporting pain 5/10; (B) Patient with COPD, SpO2 92% on 2L NC — baseline; (C) Diabetic patient with new diaphoresis and shakiness; (D) Post-cardiac cath patient, BP 88/54.

Answer: D — Hypotension post-cardiac cath suggests possible hemorrhage or vasovagal response. This is a circulation emergency (ABC). The diabetic patient (C) is also urgent but hemodynamic instability takes precedence.

Scenario 2: Appropriate delegation to UAP?

Which task is appropriate to delegate to a UAP? (A) Educating a patient about a low-sodium diet; (B) Taking vital signs on a stable post-op patient; (C) Assessing a new patient admitted for chest pain; (D) Changing a dressing on a Stage 3 pressure wound.

Answer: B — Vital signs on a stable patient are within UAP scope. Education (A) and assessment (C) require RN judgment. Complex wound care (D) requires an LPN or RN.

Scenario 3: What is the priority nursing diagnosis?

A patient with acute pulmonary edema presents with: SpO2 82%, BP 180/110, HR 118, respiratory rate 30, audible crackles bilaterally, and extreme anxiety. What is the priority nursing diagnosis?

Answer: Impaired Gas Exchange — SpO2 of 82% represents a critical oxygenation deficit. Airway and breathing are threatened before addressing hypertension or anxiety.

Scenario 4: Maslow prioritization

A newly diagnosed cancer patient says: "I'm scared about dying" and "I haven't eaten in 2 days." Which concern does the nurse address first?

Answer: Nutritional deficit (not eating) — Physiological need (nutrition) takes precedence over psychosocial (fear). After addressing nutritional status, the nurse can explore the patient's emotional concerns.

Scenario 5: Safe to leave for last?

Which client is lowest priority? (A) Patient with DVT, sudden onset shortness of breath; (B) Patient receiving blood transfusion, temp 38.5°C, new chills; (C) Patient with mild chronic back pain rating 4/10; (D) Post-op appendectomy 12 hours ago, serosanguinous drainage on dressing.

Answer: C — Chronic, stable pain is the lowest priority. Options A (possible PE), B (possible transfusion reaction), and D (expected but needs monitoring) all require more urgent assessment.
