// EMT Question · Cardiology & Resuscitation
A 62-year-old complains of substernal chest pressure radiating to the left arm. First priority after scene safety is:
A. Aspirin administration
B. Oxygen if hypoxic and rapid transportCorrect
C. Nitroglycerin
D. 12-lead ECG
// Rationale
Oxygen only if SpO2 <94% or dyspneic, and rapid transport to a PCI-capable center is the priority.
