Pathophysiology
Clinical meaning
Clinical prioritization requires systematic assessment of patient acuity and time-sensitivity of interventions. The ABCs (Airway, Breathing, Circulation) framework ensures life-threatening conditions are addressed first. Maslow's hierarchy applies to nursing prioritization: physiological needs (oxygenation, circulation, fluid balance) take precedence over safety, then psychosocial needs. The acute vs chronic framework distinguishes new/changing conditions requiring immediate intervention from stable chronic conditions. Clinical decision rules (HEART score, Wells criteria, CURB-65) standardize risk stratification. Triage systems (ESI 1-5, MTS) categorize patients by acuity: ESI-1 (immediate/resuscitation), ESI-2 (emergent/high risk), ESI-3 (urgent), ESI-4 (less urgent), ESI-5 (non-urgent). The NP must also recognize the 'can't miss' diagnoses that present with common symptoms but carry high mortality if delayed.
