Question: 1 / 400

What factors are evaluated in the Glasgow Coma Scale?

Eye opening, verbal response, and motor response

The Glasgow Coma Scale (GCS) is a clinical scale used to assess a patient's level of consciousness and neurological function following a traumatic brain injury or other medical conditions affecting consciousness. The scale evaluates three key components: eye opening, verbal response, and motor response.

Eye opening assesses the patient's ability to open their eyes spontaneously or in response to stimuli. This can indicate the level of arousal or awareness. Verbal response gauges the patient's ability to speak and respond appropriately to questions or commands, providing insight into cognitive function and orientation. Motor response measures the patient's ability to follow commands or react to stimuli with purposeful movements, which reflects motor skills and brain response to external cues.

Together, these three factors provide a comprehensive picture of a patient's neurological status and can help healthcare providers make critical decisions regarding immediate care and monitoring.
