A client diagnosed with major depressive disorder asks, “What part of my brain controls my emotions?” Which nursing response is appropriate?
The occipital lobe governs perceptions, judging them as positive or negative
The medulla regulates key biological and psychological activities
The limbic system is largely responsible for one’s emotional state
The parietal lobe has been linked to depression
The Correct Answer is C
Choice A reason: The occipital lobe primarily processes visual information, not emotions. It interprets visual stimuli but does not judge them as positive or negative, which is a function of the limbic system. This makes the statement incorrect for explaining the brain’s role in emotional regulation.
Choice B reason: The medulla oblongata regulates vital functions like heart rate and breathing, not psychological activities or emotions. Emotional regulation involves higher brain structures like the limbic system, making this statement inaccurate for addressing the client’s question about emotions.
Choice C reason: The limbic system, including the amygdala and hippocampus, regulates emotions by processing fear, pleasure, and memory. It modulates emotional responses via neurotransmitter pathways and is implicated in depression, making this the correct and most accurate response to the client’s question.
Choice D reason: The parietal lobe processes sensory information and spatial awareness, not emotions. While depression may involve broader brain dysfunction, the parietal lobe is not primarily linked to emotional regulation, making this statement incorrect compared to the limbic system’s role.

Correct Answer is C
Explanation
Choice A reason: Physical therapy focuses on physical rehabilitation through exercises and manual techniques, targeting specific musculoskeletal issues. While beneficial, it is not inherently holistic, as it does not typically address mental, emotional, or spiritual health, which are core to holistic practices, making this choice incorrect.
Choice B reason: Refusing medication is not a holistic practice; it is a personal choice that may stem from beliefs but does not inherently promote holistic health. Holistic practices involve integrative approaches like acupuncture or meditation, not simply avoiding conventional treatments, making this choice incorrect.
Choice C reason: Acupuncture is a holistic practice rooted in traditional Chinese medicine, aiming to balance energy (qi) to promote physical, mental, and emotional well-being. It addresses the whole person by stimulating specific points to regulate energy flow, aligning with holistic principles, making this the correct choice.
Choice D reason: Taking prescribed medicine is part of conventional medical treatment, focusing on specific symptoms or diseases. It does not inherently consider the mind-body-spirit connection central to holistic practices, which aim for integrative health approaches, making this choice incorrect.
Correct Answer is D
Explanation
Choice A reason: Frontotemporal lobar degeneration affects the frontal and temporal lobes, causing personality changes, language difficulties, and behavioral issues. It does not typically present with parkinsonian effects or fluctuating cognition, which are specific to Lewy body disease. The client’s stroke and parkinsonian symptoms make this diagnosis unlikely.
Choice B reason: Prion diseases, like Creutzfeldt-Jakob disease, cause rapid cognitive decline, myoclonus, and ataxia due to misfolded proteins. They do not typically feature parkinsonian effects or fluctuating cognition linked to stroke. The client’s symptoms align more with Lewy body disease, making prion disease an incorrect diagnosis.
Choice C reason: HIV-associated dementia results from HIV infection affecting the brain, causing cognitive impairment, motor dysfunction, and mood changes. While motor symptoms may occur, parkinsonian effects and fluctuating cognition are more characteristic of Lewy body disease, especially post-stroke, making HIV infection less likely in this context.
Choice D reason: Lewy body disease is characterized by parkinsonian symptoms (tremors, rigidity) due to alpha-synuclein deposits in the brain, often following stroke, and fluctuating cognition, including attention deficits and visual hallucinations. These match the client’s symptoms, as stroke can exacerbate Lewy body pathology, making this the most likely diagnosis.
