GCS and pupil findings guide neuro assessment in trauma.

• A. GCS is not used in trauma.
• B. Imaging should be delayed until GCS recovers.
• C. Establish baseline GCS, monitor trends.
• D. Unilateral dilated/nonreactive pupils suggest intracranial injury requiring urgent imaging.

Answer: (C)

The key idea is that neurological assessment in a trauma patient relies on objective, repeatable measures that let you detect change over time. Establishing a baseline Glasgow Coma Scale on arrival creates a reference point for the patient’s level of consciousness. From there, serial GCS measurements and ongoing pupil findings let you track trends—whether the patient is improving, stable, or deteriorating. A downward trend in GCS or new or evolving pupil abnormalities signals possible evolving intracranial injury or complications and prompts timely imaging and intervention.

GCS is a standard, ongoing tool in trauma care, not something you skip or wait to recover from. While unilateral dilated or nonreactive pupils are important red flags that can indicate intracranial injury requiring urgent imaging, the practice that best encapsulates how neuro status is monitored over time is establishing a baseline and watching for changes.
