The Correct Answer is B
The nurse should administer 2 tablets.
Since each tablet contains 1.5 mg of dexamethasone, to administer a dose of 3 mg, the nurse should give 3 mg / 1.5 mg/tablet = 2 tablets.
Choice A is incorrect because 1 tablet would only provide a dose of 1.5 mg.
Choice C is incorrect because 3 tablets would provide a dose of 4.5 mg.
Choice D is incorrect because 4 tablets would provide a dose of 6 mg.

Correct Answer is A
Explanation
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
This is the first step in controlling bleeding and preventing hematoma formation 1.
Applying direct pressure to the wound with a sterile gauze or a clean cloth can help stop the bleeding 2.
Choice A is not the best answer because a tourniquet should only be used as a last resort to control life-threatening bleeding from a limb 2.
Choice B is not the best answer because placing the client in a modified Trendelenburg position is not necessary for this situation.
Choice D is not the best answer because settling the client in a reclining position is not necessary for this situation.
