What is the purpose of the Glasgow Coma Scale in field assessment?

• A. Measure blood glucose
• B. Quantify level of consciousness and monitor neurologic status
• C. Assess pain tolerance
• D. Evaluate respiratory function only

Answer: (B)

The Glasgow Coma Scale is about quickly assessing a patient’s level of consciousness and watching how their neurologic status changes in the field. It scores eye opening, verbal response, and motor response to give a numeric range from 3 to 15, reflecting how awake and responsive the patient is. This quick, objective rating helps determine injury severity, guide triage decisions, and communicate findings to hospital staff, while also allowing clinicians to track deterioration or improvement during transport or after intervention. It isn’t used to measure blood glucose, assess pain tolerance, or evaluate respiratory function, which rely on separate tools and assessments.
