Clinical Judgment & Prioritization Strategies: ABCs to NGN
A 68-year-old male with a history of COPD and heart failure presents to the Emergency Department complaining of sudden shortness of breath and chest tightness. He appears anxious, is sitting in a tripod position, and is using accessory muscles to breathe. Vital signs: BP 152/94 mmHg, HR 118 bpm, RR 28 breaths/min, SpO2 86% on room air, Temperature 99.1°F (37.3°C). Lung sounds reveal diminished bases and inspiratory crackles throughout the upper lobes. The nurse notes jugular venous distension (JVD) and 2+ pitting edema in the bilateral lower extremities.

Step 1: Recognizing Cues with ABCs
The first step in clinical judgment is recognizing cues, often prioritized by Airway, Breathing, and Circulation (ABCs). Any threat to the airway takes precedence, followed by breathing efficiency and then circulatory stability.
- Airway: Patency, obstructions, or swelling.
- Breathing: Rate, rhythm, depth, and oxygenation.
- Circulation: Pulse, blood pressure, and perfusion.
