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.
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
To calculate the volume of cefixime oral suspension that the nurse should administer, you need to divide the prescribed dose (200 mg) by the concentration of the suspension (100 mg/mL).
This gives you 200 mg ÷ 100 mg/mL = 2 mL.
Therefore, the nurse should administer 2 mL of cefixime oral suspension.
Choice A is incorrect because 1.9 mL would provide a dose of 190 mg.
Choice C is incorrect because 2.1 mL would provide a dose of 210 mg.
Choice D is incorrect because 2.2 mL would provide a dose of 220 mg.
Correct Answer is C
Explanation
The nurse should set the flow rate to deliver 40 gtts/min.
This can be calculated by multiplying the infusion rate (120 mL/hr) by the drop factor (60 gtt/mL) and then dividing by the number of minutes in an hour (60 min/hr): (120 mL/hr) * (60 gtt/mL) / (60 min/hr) = 120 gtt/min
Choice A is not the best answer because setting the flow rate to deliver 20 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice B is not the best answer because setting the flow rate to deliver 30 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice D is not the best answer because setting the flow rate to deliver 50 gtts/min would provide a higher infusion rate than desired.
