Answer to Question 1

ANS: B
The nurse should administer the omeprazole at least 2 hours after the ketoconazole to prevent a drug-drug interaction. Drugs that reduce gastric acidity should be administered no sooner than 2 hours after ingestion of ketoconazole because they reduce absorption of the drug.
Drugs that reduce gastric acidity should be administered no sooner than 2 hours after ingestion of ketoconazole because they reduce absorption of the drug.
There is no need to confer with prescriber or refuse to administer the drugs as this is an appropriate drug combination.

Answer to Question 2

ANS: C
Metronidazole is used for prophylaxis in surgical procedures associated with a high risk of infection by anaerobes (colorectal surgery, abdominal surgery, vaginal surgery).
In this scenario, metronidazole is not given to inhibit the C. difficile toxin.
Metronidazole is not indicated for treatment a fungal infection, and nothing indicates that the patient has such an infection.
Metronidazole is not a broad-spectrum antibiotic.
