Answer to Question 1

ANS: C
Macrolides can increase serum levels of other drugs such as warfarin. If these drugs are used with macrolides, serum drug levels should be monitored. All macrolides have this drug interaction. Cardiovascular monitoring is not indicated. The drug may be given as long as serum drug levels are monitored.

Answer to Question 2

ANS: C
When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase.
