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.
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 D
Explanation
Choice A reason: While weight gain is a common side effect of olanzapine, simply stating this without providing management strategies does not support the client’s health.
Choice B reason: Stopping the medication abruptly without medical guidance risks relapse of psychotic symptoms and is unsafe.
Choice C reason: First-generation antipsychotics have their own significant risks, including extrapyramidal side effects, and are not automatically safer. Medication changes should only be considered if lifestyle modifications fail and under provider supervision.
Choice D reason: Encouraging healthy lifestyle changes like diet modification and exercise helps manage weight gain while maintaining medication adherence, making this the most appropriate intervention.
Correct Answer is ["A","B","D"]
Explanation
Choice A reason: Planning alternate escape routes is a core part of safety planning, ensuring the victim can exit safely even if blocked.
Choice B reason: Having an emergency bag ready allows quick departure and reduces risk of having to return to the abuser’s home.
Choice C reason: Giving the abuser information about location compromises safety and places the victim at greater risk.
Choice D reason: Establishing a signal with trusted individuals ensures the victim can get help quickly if violence escalates.
Choice E reason: Encouraging firearm purchase is not an appropriate nursing intervention due to safety risks and escalation potential. Safer protective strategies should be emphasized.
