Correct Answer: A

Rationale: Daily weighing is the most accurate method to monitor fluid retention in a child with nephrotic syndrome. Changes in weight can indicate fluid retention or loss, which is crucial in managing nephrotic syndrome. Observing for pitting edema and measuring abdominal girth are also important assessments, but daily weighing provides more immediate and precise information about fluid status.

Correct Answer: B

Rationale: In this scenario, the client is showing signs of fluid overload with tachypnea and a high pulse rate. Decreasing the saline to a keep-open rate is appropriate to prevent further fluid volume excess. This action allows for IV access to be maintained while reducing the fluid administered, helping to manage the symptoms of fluid overload.

Correct Answer: D

Rationale: A high white blood cell count, as seen in Client D, indicates infection, which may require postponing surgery to treat the infection adequately. It is crucial to address the underlying infection before proceeding with the appendectomy to prevent complications and ensure a successful surgical outcome.

Correct Answer: A

Rationale: The correct answer is A: Tardive dyskinesia. Haloperidol (Haldol) is an antipsychotic medication that can lead to tardive dyskinesia, a side effect characterized by involuntary, repetitive movements of the face and body. Monitoring for this side effect is crucial to provide timely interventions and prevent further complications.

Correct Answer: D

Rationale: Instructing the client to sit down and be quiet is a direct and assertive approach that can help de-escalate the situation safely. It sets clear boundaries and expectations for the client's behavior, which may help reduce agitation and aggression in this scenario. Offering a day pass if the client calms down (Choice A) might reinforce the aggressive behavior. Putting the client's behavior on extinction (Choice B) involves not reinforcing the behavior, but it may not directly address the immediate safety concern. Decreasing the volume on the television set (Choice C) does not address the client's behavior directly and may not effectively manage the escalating situation.
