A patient with a tumor compressing the hypothalamus presents with fluctuating body temperature, excessive thirst, frequent urination, and disrupted sleep-wake cycles. Which of the following best explains the role of the hypothalamus related to these symptoms?

Stores long-term memories and emotional responses.

Controls voluntary muscle movements and reflexes.

Processes sensory input from the environment and initiates motor responses.

Regulates homeostasis.

Answer and Explanation

The Correct Answer is D

Choice A reason: Long-term memory and emotional responses are primarily associated with the limbic system, particularly the hippocampus and amygdala, not the hypothalamus.

Choice B reason: Voluntary muscle control and reflexes are coordinated by the motor cortex and spinal cord, not the hypothalamus.

Choice C reason: Processing sensory input and initiating motor responses are functions of the thalamus and cerebral cortex. The hypothalamus is not directly responsible for this role.

Choice D reason: The hypothalamus regulates homeostasis, including body temperature, thirst, fluid balance, circadian rhythms, and hormone release. A tumor compressing this area explains the patient’s symptoms.

Correct Answer is B

Explanation

Choice A reason: Redirecting the sibling’s concern to the patient minimizes and dismisses the sibling’s anxiety. This is not therapeutic.

Choice B reason: Schizophrenia has a genetic component, especially in identical twins, but environment and other factors also play roles. This response provides accurate information while reducing unnecessary fear.

Choice C reason: Offering referral may be helpful later, but it does not immediately address the sibling’s expressed concern or provide reassurance.

Choice D reason: Saying there is a 50-50 chance is inaccurate and unnecessarily alarming. The risk is higher in identical twins but not absolute.

A. Refrain from judgmental comments about counting magazines. B. Teach the client how to use the technique of thought stopping. C. Assist the client to identify circumstances that increase anxiety. D. Remove magazines from the commons room when the client attends a group activity.

Correct Answer is ["A","B","C"]

Explanation

Choice A reason: Avoiding judgmental remarks supports therapeutic rapport and prevents worsening anxiety or defensiveness.

Choice B reason: Teaching coping strategies like thought stopping helps the client begin to manage obsessive behaviors more effectively.

Choice C reason: Identifying triggers for obsessive behaviors allows the nurse and client to develop strategies for prevention and management.

Choice D reason: Removing magazines to prevent counting avoids addressing the underlying compulsion and may increase anxiety. This approach is not appropriate in the initial care plan.
