A patient is prescribed metronidazole for intestinal amebiasis. Which of the following instructions should the nurse give to the patient regarding the drug?
A) Take the drug on an empty stomach.
B) Avoid intake of alcohol.
C) Guard against effects of photosensitivity.
D) Take phenobarbital for impaired sleep.
Ans: B
Feedback:
The nurse should instruct the patient to avoid the use of alcohol, in any form, until the course of treatment is completed. The ingestion of alcohol may cause a mild to severe reaction, with symptoms of severe vomiting, headache, nausea, abdominal cramps, flushing, and sweating. Metronidazole should be taken with food or meals, not on an empty stomach. Photosensitivity is not one of the side effects of metronidazole. Phenobarbital should be avoided, as it increases the metabolism of metronidazole.
