Answer to Question 1

ANS: C
Approximately 50 of patients receiving nitrates for acute angina attacks experience flushing and a pounding headache after administration. The headache is probably caused by dilation of meningeal blood vessels.

Answer to Question 2

ANS: C
Hypokalemia increases the risk of arrhythmias, and thus potassium levels should be corrected before these drugs are used.
