The best response in this scenario is to explain that diarrhea is likely due to the medication and advise the client to monitor the symptoms. Mebendazole, an anthelmintic agent used to treat parasitic worm infestations, can cause gastrointestinal side effects, including diarrhea, as it works by disrupting the energy metabolism of the worms, which can lead to their expulsion from the body. This effect can sometimes result in transient digestive disturbances, as the body adjusts to the medication and clears the parasites.

Monitoring is crucial as it allows the healthcare provider to assess whether the side effect diminishes over time or if it continues or worsens, which may necessitate further intervention or evaluation of the treatment regimen. This response fosters a better understanding for the client about medication effects while also ensuring they remain under supervision during their treatment.

Other responses, such as advising immediate discontinuation of the medication, may not be necessary unless the gastrointestinal issue becomes severe, as diarrhea alone does not usually warrant stopping treatment without a broader context of symptoms. Suggesting a change in diet could be inappropriate without knowing the exact cause of the diarrhea, and requesting follow-up laboratory tests may not be immediately required when the symptom is a common, known side effect of the medication.
