Final answer:
The Glasgow Coma Scale ranges from 3 to 15 and is used to assess a patient's level of consciousness.
Step-by-step explanation:
The Glasgow Coma Scale (GCS) is a scoring system used to assess the level of consciousness in patients. It measures three aspects of neurological function: eye-opening response, verbal response, and motor response. Each aspect is assigned a score, and the total score ranges from 3 to 15.
The GCS is often used in emergency medicine and intensive care units to monitor the progress of patients with head injuries or altered mental status. A higher score indicates a more favorable prognosis, while a lower score indicates a more severe neurological impairment.
