Which assessment tool is specifically designed to quantify a patient's response to stimuli in a coma?

• A. Glasgow Coma Scale
• B. Doll's Eyes Test
• C. APGAR score
• D. Mini-Mental State Examination

Answer: (A)

Quantifying a patient’s level of consciousness and responsiveness to stimuli in a coma is the key idea here. The Glasgow Coma Scale does this best because it scores three observable responses: eye opening to stimuli, verbal response, and motor response. Each domain has its own scale, totaling from 3 to 15. A lower total means deeper impairment, and tracking the score over time helps clinicians gauge how the patient is evolving, respond to treatment, and estimate prognosis.

In contrast, the Doll's Eyes Test checks a brainstem reflex (the oculocephalic reflex) to see if the brainstem pathways are intact, which is useful for assessing brainstem function but does not provide a single, standardized measure of overall responsiveness in coma. The APGAR score is designed for newborns, not adults. The Mini-Mental State Examination evaluates general cognitive function in awake patients and cannot measure responsiveness in a comatose state.
