Correct Answer: D

Rationale: The correct intervention for the nurse to initiate first is to notify the client's healthcare provider of the client's stated intent to leave the hospital. This action is crucial as it ensures that the client's care and safety are appropriately managed. Option A is not the best choice as involving the family to persuade the client may not address the client's underlying concerns. Option B is incorrect because having the client sign self-discharge papers without further assessment is not appropriate. Option C is also incorrect as the client's request for treatment does not prevent them from leaving if they are deemed competent to make that decision.

Correct Answer: B

Rationale: The correct answer is to increase sodium intake. Maintaining consistent sodium levels is crucial for patients on lithium therapy to prevent fluctuations in drug levels. Increasing caffeine intake (Choice A) is not recommended as it can interfere with lithium levels. While protein intake (Choice C) is important, it is not the essential dietary recommendation for patients on lithium therapy. Similarly, increasing fiber intake (Choice D) is not a key recommendation for these patients.

Correct Answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy is essential to prevent bleeding and promote recovery. This position helps apply pressure to the biopsy site, reducing the risk of bleeding. Choices B, C, and D are incorrect because continuing oral fluids restriction, changing the dressing, and activating the patient-controlled analgesia pump do not directly indicate compliance with the crucial post-biopsy teaching of maintaining the supine position.

Correct Answer: D

Rationale: The correct intervention for the nurse to initiate first is to notify the client's healthcare provider of the client's intention to leave the hospital. This is important to ensure that the client's care and safety are appropriately managed. Option A is incorrect as involving the family without proper assessment or intervention could violate the client's autonomy. Option B is incorrect because it does not involve the healthcare provider in the decision-making process. Option C is incorrect as it does not address the client's rights to make decisions about their own care.

Correct Answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body, not urea. Ammonia accumulates due to liver dysfunction, leading to neurological symptoms. Fatty infiltration of the liver may lead to conditions like non-alcoholic fatty liver disease, but it is not the direct cause of hepatic encephalopathy. Jaundice is a symptom of liver dysfunction but is not the primary cause of hepatic encephalopathy.
