Question

a client with giardiasis is taking metronidazole 2 grams po. which information should the nurse include in the clients instruction?

a stop the medication after the diarrhea resolves.

b avoid overexposure to the sun.

c notify the clinic of any changes in the color of urine.

d take the medication with food.

Explanation:

• Option A: Metronidazole for giardiasis needs to be taken for the full course, not stopped when diarrhea resolves. So A is incorrect.
• Option B: Metronidazole does not typically have a strong photosensitivity warning, so avoiding sun overexposure is not a key instruction. B is incorrect.
• Option C: Metronidazole can cause urine to darken, but this is a harmless side effect and not a reason to notify the clinic. C is incorrect.
• Option D: Metronidazole can cause gastrointestinal upset, so taking it with food helps reduce this. This is a correct instruction.

Answer:

D. Take the medication with food.
