Correct answer: E — Moderate head injury (GCS 9–12)

GCS 10 (E2V3M5) falls in the moderate head injury range (9–12). This patient requires urgent CT (already performed), neurosurgical consultation for the SDH, and warfarin reversal (IV vitamin K + Prothrombinex). GCS should be monitored serially. GCS <8 defines coma and warrants intubation for airway protection.
