ORMC Progressive Care Unit (PCU) Practice Test

A Glasgow Coma Scale score of 3 best indicates which level of brain function?

Severe impairment Normal function Mild impairment Moderate impairment

Correct Answer:

Severe impairment

Explanation:

Glasgow Coma Scale measures consciousness by looking at eye opening, verbal response, and motor response, with total scores ranging from 3 to 15. A score of 3 reflects no eye opening, no verbal response, and no motor response to any stimuli, which is the deepest level of unconsciousness. That state is considered coma and indicates severe impairment of brain function. Remember, a normal function is a top score of 15, and coma or severe impairment is typically associated with scores in the lower end of the scale.
