Answer to Question 1

C
Feedback:
Spironolactone (Aldactone) is an aldosterone antagonist that reduces aldosterone-induced retention of sodium and water and impaired vascular function. Thiazide diuretics, ACE inhibitors, and angiotensin IIreceptor blockers do not have this mechanism of action.

Answer to Question 2

D
Feedback:
Premedication with an antihistamine may be used to prevent allergic reactions with the administration of a transfusion of packed red blood cells. The administration of antimicrobial or antianginal is not recommended for a transfusion reaction.
