Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with a full glass of milk (Choice A) is incorrect. Avoiding direct sunlight (Choice B) is not related to erythromycin use. Taking an antacid before the medication (Choice D) can interfere with its absorption.

Correct Answer: C

Rationale: The correct instruction for a client prescribed Verapamil is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication. This can result in a higher risk of adverse effects, such as hypotension and bradycardia. Therefore, it is essential for the client to avoid grapefruit juice while taking Verapamil to prevent potential complications.

Correct Answer: D

Rationale: The client's symptoms of face spasms after receiving Prochlorperazine indicate acute dystonia, a known side effect. Diphenhydramine is commonly administered to manage extrapyramidal symptoms, such as muscle spasms, caused by medications like Prochlorperazine. Therefore, the nurse should anticipate a prescription for Diphenhydramine to alleviate the client's symptoms.

Correct Answer: B

Rationale: Obtaining help from another healthcare professional to confirm the correct client and blood product is crucial in preventing an acute hemolytic reaction during a blood transfusion. This reaction occurs due to ABO or Rh incompatibility. Verifying the correct client and blood product reduces the risk of administering the wrong blood type, which could lead to a life-threatening reaction. It is essential to follow strict protocols to ensure patient safety during blood transfusions.
