Which range accurately reflects the Glasgow Coma Scale?

• A. 1 to 15
• B. 0 to 15
• C. 3 to 15
• D. 2 to 14

Answer: (C)

The Glasgow Coma Scale gauges level of consciousness by scoring three components: eye opening, verbal response, and motor response. Each part has its own range: eye opening from 1 (no opening) to 4 (opens spontaneously); verbal response from 1 (no sound) to 5 (oriented); and motor response from 1 (no movement) to 6 (obeys commands). Adding these together gives a total that can be as low as 3 (1+1+1) and as high as 15 (4+5+6). So the valid range is 3 to 15. A score of 3 represents no responsiveness in any domain, while 15 reflects full, purposeful interaction. Ranges outside 3–15 aren’t possible because each component has a minimum of 1 and a maximum of its listed value, so totals cannot fall below 3 or exceed 15.
