Final answer:
The Glasgow Coma Scale involves eye opening, verbal response, and motor response, all of which contribute to a low score indicating a severe level of consciousness impairment.
Step-by-step explanation:
On the Glasgow Coma Scale, a low score is indicative of a severe level of consciousness impairment. All three factors - eye opening, verbal response, and motor response - contribute to the overall score. Each factor is assigned a specific score, with a lower score indicating a lower level of consciousness. For example, a patient with their eyes closed, no verbal response, and no motor response would receive the lowest score of 3 on the scale.
