Which are the three components of the Glasgow Coma Scale?

• A. Eye opening, Verbal response, Motor response
• B. Pupil size, Respiratory rate, Blood pressure
• C. Level of consciousness, Alertness, Memory
• D. Temperature, Pulse, Oxygen saturation

Answer: (A)

The Glasgow Coma Scale assesses level of consciousness using three observable responses: eye opening, verbal response, and motor response. Each component measures a different aspect of brain function that reflects arousal and neurologic integrity. Eye opening gauges how awake and responsive the person is, ranging from spontaneous opening to no opening. Verbal response evaluates orientation and speech ability, from fully oriented to incomprehensible or no spoken words. Motor response looks at purposeful movement in response to commands or pain, from obeying commands to no movement. The three scores are added together to form a total score, which helps gauge severity of brain injury and monitor changes over time. The scale does not rely on vital signs like pupil size, respiratory rate, or blood pressure, nor on broader mental-status terms like memory or alertness alone; those elements aren’t the structured components used in the Glasgow Coma Scale.
