B.

C.
Metronidazole may cause an unusual metallic taste in your mouth.
D.
Metronidazole will cause an upset stomach.
The Correct Answer and Explanation is:
The correct answer is C. Metronidazole may cause an unusual metallic taste in your mouth.
Metronidazole is an antibiotic commonly prescribed to treat bacterial infections such as bacterial vaginosis, trichomoniasis, and certain gastrointestinal infections. When providing discharge teaching to a patient prescribed metronidazole, it is crucial to inform them about possible side effects to promote adherence and manage expectations.
One notable side effect of metronidazole is a metallic taste in the mouth, which is commonly reported by patients taking the drug. This metallic taste can be unpleasant but is typically harmless. It’s important to reassure patients that this side effect is normal and often resolves once the medication course is completed. Drinking water or eating a mild snack may help reduce the intensity of the metallic taste.
Other potential side effects of metronidazole include nausea, vomiting, diarrhea, and abdominal discomfort, though these gastrointestinal symptoms are not universal. Patients should be encouraged to take the medication with food if they experience an upset stomach to minimize this discomfort.
Metronidazole does not commonly cause constipation (Answer A) or anxiety (Answer B). While gastrointestinal side effects like diarrhea or nausea are more frequent, constipation is not typically associated with this drug. Anxiety is also not a known common side effect of metronidazole.
Patients should also be advised to avoid alcohol while taking metronidazole and for at least 48 hours after the last dose. Drinking alcohol while on this medication can cause a severe reaction, including symptoms like nausea, vomiting, flushing, headache, and rapid heartbeat.
Overall, discharge teaching for patients prescribed metronidazole should emphasize common side effects, particularly the metallic taste, and provide clear guidance on managing minor symptoms, while also highlighting key precautions like avoiding alcohol.
