A patient with chest pain, hypotension, and clear lungs but new ST elevations. Which single medication should be avoided initially?

Explanation:
In this scenario the key idea is hemodynamic safety in STEMI. Nitrates lower preload by venodilation. When blood pressure is already low, pulling more blood away from the heart can drop cardiac output further and reduce coronary perfusion pressure, risking worsening shock or ongoing ischemia. If right ventricular involvement is possible, preload becomes even more critical, making nitrates especially hazardous. So avoiding nitrates initially in a hypotensive STEMI patient is the safest course. Aspirin should be given for antiplatelet effect, and oxygen is used if the patient is hypoxemic; these actions do not carry the same immediate risk to blood pressure in this context.
