While teaching the client about a diagnosed endocrine disorder, which area of the brain would the nurse include as the center in the brain that regulates hormone production?

Correct Answer: B

Rationale: The diencephalon (hypothalamus, pituitary) regulates hormone production. Cerebrum handles cognition, brainstem vital functions, cerebellum coordination.

Correct Answer: C

Rationale: Commissural fibers (e.g., corpus callosum) connect the right and left cerebral hemispheres. Decussation fibers cross midline, association fibers connect within one hemisphere, and projection fibers link cortex to lower structures.

Correct Answer: B

Rationale: The corpora quadrigemina (superior and inferior colliculi) are in the mesencephalon (midbrain), processing visual and auditory reflexes. Telencephalon is cerebrum, diencephalon includes thalamus, metencephalon is pons/cerebellum.

Correct Answer: D

Rationale: CSF is produced by the choroid plexuses but drains into venous sinuses (e.g., superior sagittal sinus), not the circle of Willis (an arterial structure). Other statements are accurate.

Correct Answer: B

Rationale: The telencephalon (cerebrum) is the most rostral brain region, farthest from the spinal cord. Myelencephalon (medulla) is closest, followed by metencephalon, mesencephalon, and diencephalon.
