Answer to Question 1

ANS: A
Dihydropyridines (amlodipine) are calcium channel blocking medications that work by inhibiting the vasoconstricting effects of calcium to cause vasodilation. Amlodipine does not have a diuretic effect or cause the heart to contract more forcefully. Calcium channel blockers do slow the heart rate; however, the dihydropyridines (amlodipine) have peripheral vasodilating effects.

Answer to Question 2

ANS: A
Aliskiren is a renin angiotensin antagonist. Eplerenone blocks the action of aldosterone.
Diltiazem is a calcium channel blocker. Reserpine depletes catecholamines.
