Final answer:
The highest numerical value for the best motor response on the Glasgow Coma Scale is 6 points, indicating that the patient is obeying commands.
Step-by-step explanation:
The question relates to the Glasgow Coma Scale (GCS), which is used to assess a person's level of consciousness. When computing the GCS, the highest numerical value assigned to the best motor response is 6 points. The GCS is divided into three components: Eye response, Verbal response and Motor response.
Each component has its own scale of responses, with eye response ranging from 1 to 4 points, verbal response from 1 to 5 points, and motor response from 1 to 6 points. A score of 6 points on motor response indicates that the patient is obeying commands, which is the best motor response possible on the scale.
