What three components make up the Glasgow Coma Scale?

• A. Eye opening, verbal response, and motor response
• B. Pupillary response, motor strength, orientation
• C. Heart rate, blood pressure, respiratory rate
• D. Verbal fluency, gait, coordination

Answer: (A)

The question tests how the Glasgow Coma Scale measures consciousness. The GCS uses three domains to assess a patient’s responsiveness: eye opening, verbal response, and motor response. Each domain is scored separately and the numbers are added to give a total score that helps gauge coma severity and monitor changes over time. The three components together—eye opening, verbal response, and motor response—are the defining parts of the scale. The other options mix up different physiological signs or functions that are not part of the GCS.
