A client diagnosed with trichomoniasis is prescribed metronidazole (Flagyl). The nurse should instruct the client to avoid which contraindication associated with this medication?
Correct answer
B
Rationale
The correct answer is B: Alcohol. Metronidazole interacts with alcohol, causing a disulfiram-like reaction, leading to nausea, vomiting, flushing, and headache. Avoiding alcohol is crucial to prevent these adverse effects. Grapefruit juice (A) is not contraindicated with metronidazole. Tyramine-based foods (C) are associated with MAOIs, not metronidazole. Dairy (D) does not have a direct contraindication with metronidazole.
