Correct Answer: C

Rationale: The correct answer is to monitor blood glucose levels closely. Prednisone can elevate blood glucose levels, necessitating close monitoring. Adjusting the insulin dose may be necessary, but this should be managed by a healthcare provider. Prednisone should be taken with food to reduce gastrointestinal discomfort and should not be stopped suddenly to prevent adverse effects.

Correct Answer: B

Rationale: The correct answer is B. The client should remove the old clonidine (Catapres) patch before applying a new one to prevent overdose. The patch is typically changed every 7 days. Avoiding alcohol consumption is important as it can potentiate the sedative effects of clonidine. It is recommended to rotate application sites to prevent skin irritation and ensure optimal drug absorption.

Correct Answer: D

Rationale: H2-receptor antagonists like Nizatidine, Ranitidine, and Famotidine are used to suppress gastric acid secretion, relieve heartburn symptoms, and prevent complications of peptic ulcer disease. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief and inflammation, but it is not an H2-receptor antagonist. It is essential to differentiate between these medication classes to ensure appropriate treatment for gastrointestinal conditions.

Correct Answer: A

Correct Answer: D

Rationale: Prostaglandin E1 is prescribed for a child with transposition of the great arteries to increase blood mixing, which helps maintain adequate oxygen saturation and cardiac output. This medication does not prevent hypercyanotic spells, maintain hormone levels, or influence the position of the great arteries.
