5. Using the ABC framework, what is the priority assessment for any client?
Explanation
ABC (Airway, Breathing, Circulation) is the foundational priority framework in nursing and emergency care. The order reflects time-to-death: without airway, death in 4-6 minutes (brain damage starts in 3 min); without breathing, similar; without circulation, similar but slightly longer. A — AIRWAY: Is it open? Is it protected (gag reflex, consciousness sufficient to clear secretions)? Signs of compromise: stridor, gurgling, snoring, choking, drooling, inability to speak. Interventions: position (head-tilt-chin-lift, jaw thrust if trauma), suction, oral/nasal airway, intubation. B — BREATHING: Rate (12-20 normal adult), depth, effort, symmetry, oxygenation (SpO2). Signs of compromise: tachypnea/bradypnea, accessory muscle use, retractions, paradoxical chest movement, cyanosis, decreased breath sounds, wheezing/crackles/rhonchi. Interventions: positioning (Fowler's), oxygen, nebulizers, ventilation support, chest tube. C — CIRCULATION: Heart rate, rhythm, blood pressure, capillary refill, skin color/temperature, pulses, mental status (early sign of perfusion problems), urine output, bleeding. Signs of compromise: tachycardia/bradycardia, hypotension, weak/absent pulses, cool/pale/diaphoretic skin, altered mental status, delayed cap refill. Interventions: control bleeding, IV access, fluids, vasopressors, CPR if pulseless. Extended frameworks: ABCDE adds D = Disability (neurological assessment), E = Exposure (full body exam, environmental control); ABCDEFG adds F = Fluids/Family, G = Glucose. Maslow's hierarchy supplements ABC: physiological needs (air, water, food, sleep, shelter, warmth) → safety → love/belonging → esteem → self-actualization. When prioritizing among clients: airway problems before breathing before circulation before disability; acute problems before chronic; unstable before stable; new findings before known issues. ABC overrides Maslow when both apply.
