Before We Start
Why prioritization is the core skill of nursing
A nurse on a typical medical-surgical floor may have 4–6 patients at once. All of them need something. Some of those needs are urgent; some can wait. Making the right call about who to see first — and what to do first when you get there — is the skill that separates safe nurses from unsafe ones.
NCLEX tests prioritization constantly because it tests clinical judgment. A student who knows all the facts but can't prioritize them correctly isn't ready to be a nurse. The ABC framework is the systematic hierarchy that guides every prioritization decision.
💡 The Hierarchy — In Order
1. Airway — always first. No airway = dead in 4 minutes.
2. Breathing — is air moving in and out effectively?
3. Circulation — is blood pumping and perfusing?
4. Safety — is the patient in immediate danger?
5. Maslow's Hierarchy — physiological before psychosocial
6. Actual problems before potential problems
7. Acute before chronic
The Priority Layers
ABC — unpacked
A — Airway
The airway is always first — no exceptions
Without a patent airway, nothing else matters. A patient with a blocked airway is dead within 4 minutes — before any other problem can kill them.
Airway problems that need immediate action:
• Stridor (high-pitched sound on inhalation — upper airway obstruction)
• Inability to speak or cry out
• Visible obstruction in the mouth or throat
• Angioedema (swelling of the tongue or throat — anaphylaxis)
• Post-extubation stridor or hoarseness
• Patient making no respiratory effort but has a pulse
Airway interventions: Positioning (head tilt-chin lift or jaw thrust), suction, oral/nasal airway, prepare for intubation.
💊 NCLEX rule: if a patient cannot speak, cry, or cough — their airway is compromised. This is always your first priority, no matter what else is happening.
B — Breathing
An open airway doesn't guarantee adequate breathing
Breathing problems that need immediate attention:
• SpO₂ below 90% (critical hypoxia)
• RR below 8 (bradypnea — opioid effect, CNS depression) or above 30 (severe distress)
• Labored breathing — accessory muscle use, nasal flaring, retractions
• Absent or diminished breath sounds on one side (pneumothorax)
• Paradoxical breathing (chest moves opposite to expected direction — flail chest)
Why breathing comes before circulation: The heart can maintain perfusion for minutes even with compromised output. The brain cannot tolerate more than 4–6 minutes of hypoxia before permanent damage begins.
💊 SpO₂ 88% + labored breathing = priority over a patient with a wound that needs redressing. Breathing problems always win.
C — Circulation
Is blood pumping and reaching vital organs?
Circulatory emergencies:
• Hypotension (systolic below 90) — especially new onset or rapidly dropping
• Tachycardia above 130 — compensatory or dysrhythmia
• Uncontrolled hemorrhage — active bleeding that isn't being controlled
• Signs of shock — pale, diaphoretic, cold extremities, altered mental status
• Chest pain with hemodynamic instability
• New cardiac dysrhythmia with symptoms
Circulation vs. breathing priority: If both B and C are compromised — breathing first. An oxygenated heart that isn't pumping well is more survivable than a pumping heart with no oxygen.
💊 BP 84/52 + HR 130 + pale + diaphoretic = shock. This is a circulation emergency. Call for help and notify provider immediately.
Safety
Immediate safety threats after ABC is addressed
Once ABC is stable, the next priority is safety — preventing immediate harm to the patient.
Safety priorities:
• Fall risk — patient trying to climb out of bed, call light out of reach
• Suicidal ideation — active safety concern overrides some physiological needs
• Seizure precautions — patient with seizure history or active seizure
• Restraints — proper documentation and monitoring
• Medication errors — wrong medication or dose about to be administered
Exception: Immediate safety threats (patient actively trying to harm themselves) can supersede some physiological needs — but never supersede ABC.
Maslow's Hierarchy
Physiological needs before psychosocial needs
After ABC and Safety, use Maslow's hierarchy to prioritize remaining needs:
Physiological (always first): Oxygen, food, water, elimination, sleep, shelter
Safety/Security: Physical safety, financial security
Love/Belonging: Relationships, family connection
Esteem: Self-confidence, achievement
Self-Actualization: Reaching full potential
NCLEX application: A patient with shortness of breath AND anxiety — treat the shortness of breath first (physiological). A patient with pain AND loneliness — treat the pain first (physiological).
💊 Physiological needs are ALWAYS addressed before psychosocial needs on NCLEX — unless there is an immediate safety threat.
Actual vs Potential
Actual problems are happening now — potential problems might happen
When two patients have needs that are at the same Maslow level, prioritize the actual problem over the potential one.
Actual problem: Patient currently in pain (pain score 8/10). This is happening now.
Potential problem: Patient at risk for falls (high MORSE score). This might happen.
See the actual pain first. Implement fall precautions on the way in or delegate to UAP while you assess pain.
Acute vs Chronic
New and changing problems take priority over stable chronic ones
A patient with chronic stable COPD who is at their baseline is less urgent than a patient with chronic COPD who is having an acute exacerbation and is more short of breath than usual.
Acute changes in chronic conditions are new problems. They require the same priority assessment as any new problem.
🏥 NCLEX-Style Prioritization Scenario
You are a nurse with four patients. It is the beginning of your shift and all four need attention. In what order do you see them?
Pt 1
68-year-old post-op hip replacement, day 2. Requesting pain medication, pain 6/10. Stable vitals.
Pt 2
52-year-old with COPD. Call light on — reports "more short of breath than usual." SpO₂ 89% on current O₂ settings.
Pt 3
74-year-old with dementia. Found climbing over bed rail attempting to get up unassisted. High fall risk.
Pt 4
44-year-old admitted for IV antibiotics. Crying, family just left, says she feels alone and scared.
Order
First: Patient 2 — Breathing (B) is compromised. SpO₂ 89% is critical. Respiratory priority over everything.
Second: Patient 3 — Safety. Patient actively attempting to fall. Immediate safety risk. Call for help/delegate while assessing Patient 2.
Third: Patient 1 — Actual physiological problem (pain). Address after safety is secured.
Fourth: Patient 4 — Psychosocial need (loneliness, fear). Physiological and safety needs of others take priority. Address as soon as possible but cannot be first.
📌 NCLEX Application
Prioritization is the most frequently tested concept on NCLEX. Every question that asks "which patient do you see first?" or "what is the priority action?" is testing ABC + Maslow.
The fastest NCLEX approach:
1. Is anyone's airway compromised? → See them first.
2. Is anyone having a breathing problem? → See them next.
3. Is anyone hemodynamically unstable? → See them next.
4. Is anyone in immediate danger? → Address safety.
5. Who has the most urgent physiological need? → See them.
6. Psychosocial needs last — always.
NCLEX trap: Emotionally compelling scenarios (patient crying, patient scared, patient asking questions) are almost always psychosocial — and almost always last.
⚠️ The Trap — Choosing the Emotionally Compelling Answer
NCLEX question writers are experts at making psychosocial needs sound urgent. A patient who is "crying inconsolably" or "saying goodbye to family" triggers a strong emotional response — and that's exactly what the question is testing.
The student who hasn't internalized ABC priority picks the emotional answer. The nurse who has internalized it asks: is anyone's airway, breathing, or circulation compromised? If yes — that patient comes first, regardless of how compelling the emotional scenario is.
Feelings are important. Feelings are not a physiological emergency. Feelings can wait four minutes. Hypoxia cannot.
✓ Quick Prioritization Practice
Rank these patient needs from highest to lowest priority:
A. Patient reports nausea after lunch
B. Patient with new onset stridor after extubation
C. Patient crying because family hasn't visited
D. Patient with BP 86/50, HR 128, pale and diaphoretic
E. Patient with wound dressing that needs changing
Answer — Priority order:
1. B — Airway (stridor = airway obstruction)
2. D — Circulation (signs of shock)
3. A — Physiological (nausea = actual problem)
4. E — Physiological (wound care = actual but not urgent)
5. C — Psychosocial (last — important but not physiological)
