Which statement best describes the Glasgow Coma Scale components?

• A. Eye opening, Verbal response, and Motor response
• B. Breathing, Circulation, and Disability
• C. Pupillary response, Motor tone, and Sensation
• D. Heart rate, Respiratory rate, and Blood pressure

Answer: (A)

The Glasgow Coma Scale assesses consciousness using three observable responses: eye opening, verbal response, and motor response. Each component has its own range of scores (eye opening 1–4, verbal 1–5, motor 1–6), and the total score (3–15) reflects overall level of responsiveness, with higher scores indicating better function. This is why the statement describing eye opening, verbal response, and motor response is the best choice. The other options describe different physiologic signs or neurologic assessments not included in the GCS, such as breathing and circulation, pupillary or motor tone considerations, or vital signs. For context, a fully alert patient who opens eyes spontaneously (E4), is oriented and speaks clearly (V5), and follows commands (M6) would score 15.
