Which action should be performed first when a patient presents with crushing chest pain and diaphoresis?

• A. Apply oxygen therapy only.
• B. Activate emergency response/rapid assessment and obtain an ECG; administer aspirin if not contraindicated.
• C. Call a doctor to schedule a stress test.
• D. Ignore symptoms and monitor at home.

Answer: (B)

Crushing chest pain with diaphoresis signals possible acute coronary syndrome, where time to treatment matters because heart muscle loss increases with delays. The priority action is to mobilize emergency response and start rapid assessment, obtaining an ECG as soon as possible to determine if a STEMI or other ACS is present and to guide urgent reperfusion decisions. While awaiting further care, give aspirin to inhibit platelets and reduce mortality, provided there are no contraindications. Oxygen should be reserved for patients with hypoxemia or signs of inadequate oxygenation, not given automatically to every ACS patient. Scheduling a stress test or waiting at home would delay critical, life-saving interventions. This combination—EMS activation with immediate ECG and aspirin—addresses the urgency of suspected ACS and helps initiate timely treatment.
