A nurse is reinforcing teaching with a patient who has hypertension and a new prescription for verapamil.

The nurse should instruct the patient to avoid taking this medication with which of the following foods?

Grapefruit.

Spinach.

Broccoli.

Carrots.

Answer and Explanation

The Correct Answer is A

The nurse should instruct the patient to avoid taking verapamil with grapefruit.
Studies have demonstrated an interaction between verapamil and grapefruit juice, which is likely due to an inhibition of intestinal metabolism resulting in increased oral bioavailability1.
This means that grapefruit can interfere with the enzymes that break down verapamil in your digestive system, potentially leading to dangerous health problems2.
Choices B, C, and D are incorrect because there is no known interaction between verapamil and spinach, broccoli, or carrots.

Correct Answer is B

Explanation

The nurse should administer 2 tablets of lorazepam 1 mg to give a total dose of 2 mg.
This is calculated by dividing the desired dose (2 mg) by the available dose (1 mg/tablet) to get the number of tablets needed: 2 mg / (1 mg/tablet) = 2 tablets.
Choice A, 1 tablet, is not the correct answer because it would only provide a total dose of 1 mg.
Choice C, 3 tablets, is not the correct answer because it would provide a total dose of 3 mg.
Choice D, 4 tablets, is not the correct answer because it would provide a total dose of 4 mg.

Correct Answer is ["1"]

Explanation

The physician has ordered a total of 2 g/day of vancomycin hydrochloride to be taken in 4 divided doses.

This means that each dose should be 2 g/day ÷ 4 = 0.5 g/dose.

Since the pharmacy has filled the prescription with 500 mg capsules, and 500 mg is equivalent to 0.5 g, the client should take 1 capsule per dose.
