What is the minimum and maximum Glasgow Coma Scale score?

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

Answer: (A)

The Glasgow Coma Scale assesses level of consciousness in three parts: eye opening, verbal response, and motor response. Each part has its own scoring range: eye opening from one to four, verbal response from one to five, and motor response from one to six. Since the lowest score you can give in any domain is one, the smallest total you can achieve is one plus one plus one, which equals three. Conversely, the highest scores in each domain are four, five, and six, so the largest total is four plus five plus six, which equals fifteen. Therefore, the overall score can range from three to fifteen.
