Answer to Question 1
A
The patient should be instructed to avoid alcoholic beverages, because a disulfiram-like reaction can occur if metronidazole is taken with alcohol. Nothing indicates that the patient should avoid foods containing tyramine. Metronidazole may be taken with or without food.
Answer to Question 2
D
A beta blocker, such as propranolol, should not be given if the pulse is lower than 60 beats per minute; therefore, the nurse should withhold the dose and notify the prescriber. Administering the dose as prescribed would not be appropriate, because the patient's pulse rate is too slow at this time. The dose should be withheld and the prescriber notified. The patient's heart rate is slow, and atropine may be necessary if the bradycardia persists, but the first step is to withhold the dose of propranolol. Withholding the dose and documenting the pulse rate is an appropriate but incomplete nursing intervention. The nurse must notify the prescriber to obtain further orders related to the medication.
