The nurse is testing deep tendon reflexes (DTR) on a client. The nurse is aware that stimulation of the tendon produces which kind of physiological response?

Correct Answer: B

Rationale: DTRs (e.g., knee jerk) are somatic reflexes involving skeletal muscle via spinal cord, not autonomic (visceral), sympathetic, or parasympathetic responses.

Correct Answer: B

Rationale: The cerebrum does comprise ~80% of brain mass, has a convoluted gray matter cortex, and is the telencephalon. However, it has four lobes per hemisphere (frontal, parietal, temporal, occipital), not 'four paired lobes' as a distinct entity, making B false.

Correct Answer: B

Rationale: Parkinson’s disease results from basal ganglia dysfunction (e.g., dopamine loss in substantia nigra), affecting motor control. The pons, parietal lobe, and thalamus have other roles; 'corpus striatum' is part of basal ganglia but less specific.

Correct Answer: B

Rationale: The corpus callosum connects cerebral hemispheres and has no autonomic role like blood pressure regulation. Pons and medulla regulate respiration, thalamus relays pain, and hypothalamus controls temperature.

Correct Answer: C

Rationale: The cerebral aqueduct (in the midbrain) connects the third ventricle to the fourth ventricle, allowing CSF flow. Lateral ventricles connect to the third via the interventricular foramina.
