Rationale: The correct answer is B. Increased thirst and fluid intake, such as drinking more soft drinks than previously, is a common symptom of diabetes mellitus in children. This increased thirst is due to the body trying to eliminate excess sugar through urination, leading to dehydration and the need for more fluids.

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.
