Answer to Question 1

Correct Answer: 4
Rationale: Beta blockers reduce myocardial oxygen demand, which is critical for patients who have experienced a recent myocardial infarction (MI). Unless contraindicated, beta-blocker therapy continues for the remainder of the patient's life. Beta-blocker therapy must continue for the remainder of a patient's life, this is not based on the results of a test. Beta blockers are taken on a scheduled basis, not as needed (prn); this statement refers to nitrates. Beta blockers are not used prophylactically; this statement refers to nitrates.

Answer to Question 2

Correct Answer: 1
Rationale: The primary means by which antianginal drugs terminate an acute angina episode, or decrease the frequency of angina episodes, is by reducing the myocardial demand for oxygen. Antianginal medications cannot increase the oxygen supply to the myocardium. Antianginal medications do not have an anticoagulant effect. Antianginal medications do not increase nitric acid production.
