Answer to Question 1

ANS: A
Alpha-adrenergic blockers can cause orthostatic hypotension and reflex tachycardia. Beta blockers do not cause reflex tachycardia. Decreasing or increasing the drug dose is not recommended. Diuretics are added if blood pressure is not well-controlled.

Answer to Question 2

ANS: D
Alpha-adrenergic blockers can be used to treat peripheral vascular disease because they cause vasodilation.
