What is the valid range for the eye-opening component of the Glasgow Coma Scale?

Explanation:
The eye-opening score on the Glasgow Coma Scale measures how the patient responds to stimuli and ranges from 1 to 4. A score of 4 means eyes open spontaneously, 3 means they open in response to verbal commands, 2 means they open to a painful stimulus, and 1 means no eye opening at all. So the valid range is 1 through 4. The other ranges listed would contradict how this component is defined: they either include a non-existent 0, or exceed the maximum value assigned to eye opening (which is 4).
