Patients with closed head injuries often have pupillary abnormalities and:

Explanation:
Pupillary changes after a closed head injury often signal rising intracranial pressure with potential brainstem involvement. When ICP climbs, the body invokes the Cushing reflex to maintain cerebral perfusion, which shows up as high systolic blood pressure (hypertension) paired with a slow heart rate and irregular respirations. That link—pupil abnormality with hypertension due to this reflex—explains why hypertension is the best match. Paralysis, tachycardia, or paresthesias aren’t specifically tied to the pupil changes seen with increased ICP in this context.
