Rationale: When given sublingually, nitroglycerin reaches peak plasma levels within minutes, thus quickly terminating angina pain. Chest pain that does not respond within 10 to 15 minutes after two or three doses of sublingual nitroglycerin may indicate MI, and emergency medical services (EMS) should be contacted.

Rationale 1: Thrombolytic drugs do not prevent formation of a clot; they only break down existing clots.
Rationale 2: Thrombolytic drugs are used to dissolve clots that are already formed in early stages of myocardial infarction.
Rationale 3: Thrombolytic therapy might contribute to relief of angina because thrombolytics dissolve the clot, but this is not their chief action or the reason they are given.
Rationale 4: Antiplatelet drugs prevent platelet aggregation. Thrombolytic drugs are used to dissolve clots.
