Answer to Question 1

ANS: B
Sulfonamides are bacteriostatic, not bactericidal. They are not derived from biologic substances. They are not antifungals or antivirals. They act by decreasing bacterial synthesis of folic acid.

Answer to Question 2

ANS: D
Gentamicin can cause nephrotoxicity. When changes in urine output occur, the provider should be notified, and serum trough levels should be obtained to make sure the drug is not at a toxic level. If the drug level is determined to be safe, giving extra fluids either orally or intravenously may be indicated. Serum peak levels give information about therapeutic levels but are not a substitution for avoiding nephrotoxicity in the face of possible oliguria.
