Answer to Question 1

ANS: B
Nitroglycerin is given sublingually to avoid first-pass metabolism by the liver, which would occur if the drug is swallowed. It does not prevent hypotension. Gastrointestinal upset and hepatotoxicity usually do not occur.

Answer to Question 2

ANS: D
The pounding headache is related to vasodilation of the cerebral vessels. Nitrates decrease blood pressure.
