· question 61 (1.11 points)
which auxiliary label should be affixed to a prescription bottle containing metronidazole?
avoid alcohol
take with food
take all of the medication

Explanation:

• For the first question: Isotretinoin is highly teratogenic (can cause birth defects). Pregnant females should avoid it. Benzoyl peroxide is generally considered safe topically in pregnancy. Cephalexin (a cephalosporin antibiotic) and clindamycin (an antibiotic) can be used in pregnancy when indicated.
• For the second question: Metronidazole can cause a disulfiram - like reaction (nausea, vomiting, flushing, etc.) when taken with alcohol. While some medications may have "Take with food" or "Take all of the medication" labels for other reasons, the key interaction for metronidazole is with alcohol.

Answer:

• First question: isoretinoin
• Second question: Avoid alcohol
