Answer to Question 1

A
Feedback:
Telithromycin is a potent CYP3A4 inhibitor. Combination of this drug with several medications, including corticosteroids, results in an increased serum concentration of these other drugs.

Answer to Question 2

C
Feedback:
People with hepatic impairment should not receive this combination agent on an ongoing basis. They may not metabolize acetaminophen in this combined medication effectively, leading to hepatotoxicity. Lack of previous adherence, cigarette smoking, and the presence of skin ulcers do not necessarily contraindicate the use of this drug.
