Answer to Question 1

B
Ketoconazole inhibits steroid synthesis in humans, and in females it reduces estradiol synthesis, causing menstrual irregularities. It is not an indication that oral contraceptive pills (OCPs) are needed. Because it is reversible, there is no indication for withdrawing the drug until treatment is complete. Menstrual irregularities are not a sign associated with hepatotoxicity.

Answer to Question 2

D
Voriconazole can interact with many drugs. It should not be combined with drugs that are po-werful P450 inhibitors, including phenobarbital, because these can reduce the levels of vorico-nazole. Administering the voriconazole IV will not increase the serum level. It is not correct to reduce the dose of either drug.
