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
Choice A rationale: Asymmetric facial movement might be associated with damage to other cranial nerves, not specifically cranial nerve III.
Choice B rationale: Uvula deviation is a sign of damage to the glossopharyngeal (IX) and vagus (X) nerves, not cranial nerve III.
Choice C rationale: Anosmia, the loss of sense of smell, is not typically associated with cranial nerve III dysfunction.
Choice D rationale: Damage to cranial nerve III (oculomotor nerve) can lead to ptosis, the drooping of the eyelid.
Correct Answer is D
Explanation
Choice A rationale: Activates the rapid response team (RRT) - Status epilepticus is a medical emergency requiring immediate intervention. Activating the rapid response team would ensure a prompt response to the situation.
Choice B rationale: Loosens any restrictive clothing - It is important for patient safety and comfort.
Choice C rationale: Places the client in a lateral position - This is a recommended positioning to prevent aspiration during a seizure.
Choice D rationale: Prepares to administer intravenous valproate acid - Valproic acid is not the first drug during epilepsy hence this action would necessitate immediate intervention.
