Question 5 of 5
An 18-year-old woman comes to the physician because of nausea, vomiting, and abdominal pain 1 hour after ingesting a glass of wine with dinner. Three days ago, she began antibiotic treatment for vaginitis after a wet mount preparation of vaginal discharge showed a motile protozoan. This patient most likely has been taking which of the following drugs?
Correct Answer: D
Rationale: The motile protozoan indicates Trichomonas vaginalis, treated with metronidazole (D). Metronidazole causes a disulfiram-like reaction with alcohol, leading to nausea, vomiting, and abdominal pain due to acetaldehyde accumulation from inhibited aldehyde dehydrogenase. Ceftriaxone treats bacterial infections, chloroquine malaria, and clindamycin anaerobic bacteria—none target protozoa or cause this reaction with alcohol.
