Question

the nurse is teaching a group of patients about how schizophrenia changes the structures of the brain. which information should the nurse include in the presentation?

select all that apply.

lower brain volume
shrinking of the cerebral ventricles
atrophy of the cerebral cortex
increased glucose level in the brain
decreased blood flow to the brain

Explanation:

Analyze structural and functional brain changes in schizophrenia

• Schizophrenia is associated with overall lower brain volume (gray matter loss).
• It is characterized by enlargement (dilation) of the cerebral ventricles, not shrinking. Thus, "Shrinking of the cerebral ventricles" is incorrect.
• Cortical atrophy (specifically in the frontal and temporal lobes) is a well-documented structural change.
• Neuroimaging studies show decreased (hypofrontality), not increased, glucose metabolism and decreased blood flow in prefrontal areas during cognitive tasks.

Evaluate the given options

• "Lower brain volume": Correct (structural change).
• "Shrinking of the cerebral ventricles": Incorrect (ventricles enlarge).
• "Atrophy of the cerebral cortex": Correct (structural change).
• "Increased glucose level in the brain": Incorrect (decreased glucose utilization/metabolism is observed).
• "Decreased blood flow to the brain": Correct (reduced frontal lobe perfusion/hypofrontality).

Answer:

• Lower brain volume (Correct answer)
• Shrinking of the cerebral ventricles
• Atrophy of the cerebral cortex (Correct answer)
• Increased glucose level in the brain
• Decreased blood flow to the brain (Correct answer)
