Question

a client who has trichomonas vaginalis receives a prescription for metronidazole. which instruction should the nurse provide during client education? do not ingest with dairy products. notify the clinic if the urine changes color. obtain liver function tests every 3 months. avoid over - the - counter antitussives.

Explanation:

1. Analyze each option:

• Option 1: Metronidazole has an interaction with dairy products (specifically calcium - rich dairy as it can affect absorption), so instructing not to ingest with dairy is correct.
• Option 2: Metronidazole can cause urine to turn dark brown or red - brown, which is a normal side effect and does not require notifying the clinic.
• Option 3: Routine liver function tests every 3 months are not a standard instruction for metronidazole use unless there are pre - existing liver issues or signs of liver problems.
• Option 4: There is no interaction between metronidazole and over - the - counter antitussives, so this instruction is not needed.

Answer:

A. Do not ingest with dairy products.
