Answer to Question 1

ANS: C
The azoles class of antifungals is less toxic than amphotericin B. Amphotericin B may only be given parenterally. The azoles, not amphotericin B, inhibit hepatic P450 drug-metabolizing enzymes, so they increase the levels of many other drugs. Both classes are broad-spectrum antifungal agents.

Answer to Question 2

ANS: B
Patients receiving amphotericin frequently experience infusion reactions, with fever, chills, rigors, nausea, and headache. Pretreatment with diphenhydramine and acetaminophen can reduce mild reactions. If rigors occur, the patient should receive dantrolene or meperidine. Aspirin would be effective for pretreatment but can increase kidney damage. Hydrocortisone is also effective, but it causes immune suppression. Omeprazole is not indicated.
