Let me be honest, priority questions are the NCLEX's favorite trick. All four answer choices are correct nursing actions, but only one of them is the most urgent, and that's the one they want. This post gives you the four-layer framework I lean on. ABCs, Maslow, safety, and the "stable vs unstable" rule. Run them in order and you'll land on the right answer almost every time.
What is a priority question?
A priority question asks you to rank a bunch of correct options and pick the one that comes first. The good news is they're easy to spot. The stem will use words like:
- "First": "Which action should the nurse take first?"
- "Priority": "What is the nurse's priority?"
- "Most important": "Which finding is most important to report?"
- "Best": "Which is the best initial action?"
- "Initially": "How should the nurse initially respond?"
- "See first": "Which client should the nurse see first?"
Here's the trap. All four options will usually be legit things a nurse would actually do. So your job isn't to find the "right" answer the way you normally think about it. It's to find the highest-ranking one.
The 4-layer priority framework
Apply these in order, and stop as soon as one of them gives you the answer. You don't need to check the rest.
Layer 1: ABCs (Airway → Breathing → Circulation)
This is the foundation of every priority decision. Anything threatening the airway always wins. Anything threatening breathing comes second. Anything threatening circulation comes third. That order never changes.
| Rank | Concern | Examples |
|---|---|---|
| A | Airway | Stridor, choking, anaphylaxis with airway swelling, tongue obstruction, foreign body, drooling with epiglottitis |
| B | Breathing | Respiratory rate < 10 or > 30, SpO₂ < 90%, severe dyspnea, absent breath sounds, tension pneumothorax |
| C | Circulation | Hypotension, severe bleeding, chest pain, dysrhythmias, signs of shock, no pulse |
A client in respiratory distress always comes before a client with chest pain. A client with chest pain always comes before a client with infection. Even if the lower-ranked client is sicker overall, the higher ABC concern wins on the question. That's just how it works.
Layer 2: Maslow's hierarchy (physiologic before psychosocial)
When two answers both pass the ABCs test, Maslow is what breaks the tie:
- Physiologic needs: oxygen, water, food, elimination, pain, rest. Always wins.
- Safety/security: physical safety, fall prevention, infection control, freedom from harm.
- Love/belonging: relationships, support systems, family.
- Self-esteem: dignity, autonomy, confidence.
- Self-actualization: achievement, fulfillment.
In plain terms: if one option is about pain control and another is about anxiety, pain wins, because physiologic beats psychosocial. If one is about bleeding and another is about fall prevention, bleeding wins (that's Layer 1 ABCs and Layer 2 physiologic both pointing the same way).
Layer 3: Safety (acute risk of harm)
When ABCs and Maslow don't separate two options, look for the one that prevents imminent harm. For example:
- An unsteady older adult trying to ambulate without help > a stable client asking for more pain medication
- A confused client trying to climb over a bed rail > a comfortable client asking for water
- A suicidal client with a means/plan > a depressed client without expressed intent
- An IV pump alarming on a vasoactive drip > a routine IV maintenance fluid that just finished
Layer 4: "Stable vs unstable" or "expected vs unexpected"
When you're ranking multiple clients ("which client should the nurse see first?"), use this rule:
See the unstable client before the stable one. See the unexpected finding before the expected one.
What counts as "expected" vs "unexpected" depends on the situation:
- A 1-hour-post-op patient with a small amount of bright red drainage = expected. A 1-hour-post-op patient with a saturated dressing = unexpected.
- A diabetic with a fingerstick glucose of 90 mg/dL = expected/stable. A diabetic with a fingerstick of 250 mg/dL who suddenly looks lethargic = unexpected.
- A client with COPD with crackles in the lower lobes = chronic/expected. A client with COPD now confused and lethargic = acute/unexpected.
Walkthrough: Worked priority question
Question: The LPN is assigned to four clients. Which client should the nurse assess first?
A. A 65-year-old with COPD who is dyspneic with an oxygen saturation of 88% on 2L O₂ via nasal cannula
B. A 78-year-old 2 days post-hip replacement who reports pain rated 7/10
C. A 45-year-old with newly-diagnosed diabetes mellitus who is asking questions about insulin
D. A 30-year-old with a UTI who is requesting more water
Apply Layer 1 (ABCs): Option A has a breathing concern. SpO₂ 88% on supplemental oxygen with active dyspnea. That's a "B" issue, so you stop right there. A wins.
Answer: A. Notice that B (pain), C (anxiety/teaching), and D (thirst/comfort) are all real nursing concerns. But they're all lower on the ABCs ladder. The respiratory client comes first, every time.
Walkthrough: A trickier example
Question: Four clients on a medical-surgical unit need attention. Which client should the LPN assess first?
A. A 70-year-old with pneumonia and an oxygen saturation of 94% on room air
B. A 55-year-old 12 hours post-cholecystectomy with a temperature of 99.8°F
C. A 60-year-old admitted yesterday with a deep vein thrombosis (DVT) who suddenly reports chest pain and dyspnea
D. A 40-year-old with cellulitis whose IV antibiotic is due in 15 minutes
Apply Layer 1 (ABCs): Option A has a "B" concern but it's stable (SpO₂ 94% is acceptable, room air, no active distress mentioned). Option C is the show-stopper. Sudden chest pain plus dyspnea in a DVT patient = suspected pulmonary embolism, which is a B+C emergency. The others get eliminated.
Answer: C. A DVT patient with sudden dyspnea and chest pain is presumed to have a PE until proven otherwise. This is the worst possible outcome of a DVT and it needs you right now. The other clients are either stable (A) or have expected, non-emergent issues (B and D).
The "expected" trap
NCLEX writers love handing you expected abnormal findings as distractors. These are findings that look scary on paper but are actually normal for the patient's situation. A few worth memorizing:
| Situation | Expected finding (NOT a priority) | Unexpected finding (PRIORITY) |
|---|---|---|
| Sickle cell crisis | Joint pain, mild fatigue | Sudden chest pain (acute chest syndrome) |
| Post-op day 1 | Pain, low-grade fever (<100.4°F), grogginess | Saturated dressing, hypotension, no urine output |
| CHF with diuretic | Mild thirst, slight K+ drop | Severe weakness, K+ 2.8, dysrhythmia |
| Asthma exacerbation | Audible wheezing | Silent chest (no wheeze = severe airflow loss) |
| Anticoagulant therapy | Mild bruising, gum bleeding when brushing | Hematuria, frank GI bleeding, headache |
| End-of-life care | Decreased appetite, increased sleep | Acute air hunger, severe pain not relieved by meds |
Special priority rules to memorize
"What action should the nurse take FIRST" for an emergency
For codes, falls, or sudden deteriorations, the first action is almost always assessment. You confirm what's actually happening before you call for help, intervene, or notify. The one exception is an obvious airway emergency (choking, airway obstruction), where the action is the assessment (open the airway, attempt a rescue breath).
For seizures, the first action is to PROTECT
Protect the head, move objects away, turn the client to the side after the seizure ends. Do not put anything in the mouth, and do not restrain them. Time the seizure. Only after it ends do you fully assess and notify.
For chest pain, aspirin and an ECG come first
You may still see the MONA memory aid (Morphine, Oxygen, Nitroglycerin, Aspirin) on the NCLEX-PN. But remember it's a recall device, not the order of priority. For suspected cardiac chest pain the real priorities are: aspirin (chewed, unless contraindicated) and a 12-lead ECG first; oxygen only if SpO₂ is below ~90% or the client is short of breath; nitroglycerin for ongoing ischemic pain (hold if hypotensive, on a recent erectile-dysfunction drug, or right-ventricular MI is suspected); morphine last, only for pain not relieved by nitroglycerin.
For preeclampsia/eclampsia, the priority is seizure prevention
Magnesium sulfate is given to prevent seizures. The priority assessment is checking deep tendon reflexes, respiratory rate, and urine output for magnesium toxicity. Calcium gluconate is the antidote.
For ICP increase, the priority is reducing pressure
Head of bed at 30°, head and neck in midline (no flexion or rotation), and avoid coughing/straining/Valsalva. Stool softeners are typical because straining raises ICP.
Common priority question traps
1. "It would be appropriate to..."
Some priority questions word the answers as "the nurse should also..." or "it would be appropriate to..." This is testing whether you can spot the most appropriate option, not just an appropriate one. Apply ABCs first.
2. Distractors that sound urgent but aren't
"The client reports severe pain" sounds urgent. But if the question also lists a client with respiratory distress, the respiratory client wins. Pain is a Maslow Layer 1 concern, true, but it still ranks below ABCs.
3. The "everything is true" question
When all four options look correct, slow down and remind yourself this is a ranking exercise, not a true/false exercise. Run ABCs, then Maslow, then safety, then stable/unstable in order until one option clearly outranks the rest.
4. Confusing "first" with "only"
"Which action should the nurse take first?" doesn't mean the other actions are wrong. It means the right answer should come before them. All four answers may be appropriate. Only one is first.
Practice prompt: try these on your own
- An LPN is reviewing four clients. Who should be seen first?
- A. A client with a stage 2 pressure ulcer being repositioned
- B. A client with COPD whose new oxygen saturation is 84%
- C. A client refusing dinner due to nausea
- D. A client requesting a PRN sleep aid
- A post-op client is drowsy and actively vomiting. Which action is the priority?
- A. Administer the PRN antiemetic
- B. Assess for hypotension and bleeding
- C. Notify the surgeon
- D. Position the patient on their side
Answers: #1 = B (ABCs, breathing). #2 = D (immediate safety, prevent aspiration; THEN assess, then medicate, then notify).

FAQ
Are priority questions the hardest NCLEX questions?
For most students, yes. But honestly they're hard because they need a framework, not because the content is hard. Once ABCs, then Maslow, then safety is second nature, priority questions get predictable.
What if two answers are both ABCs issues?
Compare how bad each one is. A patient in respiratory distress beats a patient with a known stable respiratory diagnosis. A patient with active hemorrhage beats a patient with controlled minor bleeding. Pick whoever is most acutely unstable.
How many priority questions are on the NCLEX-PN?
There's no official percentage. The NCLEX-PN Test Plan doesn't break out "priority questions" as their own category. But prioritization shows up across every content area, and Coordinated Care (where it concentrates) is 18–24% of the exam.
Where can I practice priority questions?
Start with the free practice quizzes. Every subject has priority-style questions mixed in, with a rationale on every single one. When you want full-length, exam-style sets, the paid NCLEX-PN QBank ($39 for 30 days, one-time, no auto-renew) has them across all 8 nursing subjects. Either way, read the rationale on every one you miss, that's where the learning happens.
