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 C
Explanation
Unopened vials of insulin should be kept in the refrigerator at a temperature between 36°F to 46°F (2°C to 8°C) 1.
This helps to ensure that the insulin remains safe and effective until its expiration date.
Choice A is incorrect because insulin injected into the abdomen is absorbed more rapidly than insulin injected into other areas such as the thigh.
Choice B is incorrect because insulin should not be shaken vigorously as this can cause it to break down and become less effective.
Instead, gently roll the bottle between your hands to mix it.
Choice D is incorrect because not all types of insulin can be mixed together in the same syringe.
Only certain types of insulin can be mixed together and this should only be done under the guidance of a healthcare provider.
Correct Answer is A
Explanation
Protamine is a medication that can be used to reverse the effects of heparin in the event of an overdose.
It binds to heparin and neutralizes its anticoagulant effects.
Choice B is not correct because glucagon is used to treat low blood sugar, not heparin overdose.
Choice C is not correct because oxygen is not a medication and is not used to treat heparin overdose.
Choice D is not correct because insulin is used to lower high blood sugar levels, not to treat heparin overdose.
