A client with diffuse axonal injury is experiencing difficulty with respiration, heart rate, blood pressure. Which region of the brain does the nurse suspect to be affected?
Cerebral motor cortex
Brain stem
Broca's area
Occipital lobe
The Correct Answer is B
Choice A rationale: Cerebral motor cortex primarily controls voluntary movements, not autonomic functions like respiration, heart rate, and blood pressure.
Choice B rationale: The brain stem controls vital functions like respiration, heart rate, and blood pressure, so damage to this area can lead to difficulties in these functions.
Choice C rationale: Broca's area is responsible for speech production and is not directly involved in autonomic functions.
Choice D rationale: The occipital lobe is primarily associated with visual processing and perception, not autonomic functions like respiration or heart rate.

Explanation
