Correct Answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.

Correct Answer: A

Rationale: The correct answer is A because transferring a stable client who is learning self-care, such as self-administering insulin injections after being diagnosed with diabetes mellitus, provides the needed telemetry-monitored bed without compromising the client's care. Choice B should not be transferred as the client is ambulatory following surgery and does not require telemetry monitoring. Choice C should not be transferred as the client is wearing a sling immobilizer following pacemaker insertion, which requires close monitoring. Choice D should not be transferred as the client is experiencing syncopal episodes due to severe dehydration, necessitating telemetry monitoring for immediate intervention.

Correct Answer: B

Rationale: Offering blood pressure screening and monitoring is crucial for young adults as it helps in the early detection and management of hypertension, a condition that often goes unnoticed. High blood pressure can lead to serious health issues if left untreated. While education on smoking cessation, safe sex practices, healthy diet, and exercise are important aspects of overall health promotion, blood pressure screening takes precedence due to its immediate impact on health and the prevention of potential complications.

Correct Answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

Correct Answer: D

Rationale: The most important information for the nurse to provide the client in this situation is that using both a diaphragm and a condom together provides effective contraception and also protects against sexually transmitted diseases (STDs). While oral contraceptives can help prevent unwanted pregnancies, using a barrier method like a diaphragm and a condom is crucial in this scenario where the client is engaging in a new sexual relationship. Choice B is important information but is not the top priority in this context. Choice C, although relevant, does not address the immediate concern of contraception and STD prevention. Therefore, the correct answer is D.
