Answer to Question 1

ANS: D
Because nitroglycerin can cause hypotension, patients should be cautioned to take them while sitting or lying down. If pain is not better or has worsened 5 minutes after the first dose, patients should call 911. The tablets must dissolve under the tongue and should not be swallowed.

Answer to Question 2

ANS: D
Verapamil is a calcium channel blocker and is used to relax coronary artery spasm in patients with variant angina. It does not facilitate coronary muscle oxygen use, improve renal function, or increase cardiac contractility.
