Which are the three components of the Glasgow Coma Scale?

• A. Blood pressure, Heart rate, Respiratory rate
• B. Eye opening, Verbal response, and Motor response
• C. Temperature, Oxygen saturation, Perfusion
• D. Alertness, Orientation, Memory

Answer: (B)

The Glasgow Coma Scale assesses level of consciousness by looking at three domains of responsiveness: eye opening, verbal response, and motor response. Eye opening measures arousal (from spontaneous opening to no opening at all). Verbal response assesses communication and orientation (from oriented and coherent speech to none). Motor response gauges purposeful movement in reaction to commands or to painful stimuli (from obeying commands to no movement). Each domain has its own scoring range, and adding the three scores gives the overall scale from 3 to 15, used to gauge severity and track changes over time. The other options describe vital signs or cognitive aspects that aren’t part of the Glasgow Coma Scale.
