Which tool is used to assess level of consciousness in a patient with brain injury?

• A. Glasgow Coma Scale
• B. APGAR score
• C. Braden scale
• D. MMSE

Answer: (A)

Measuring level of consciousness after brain injury is done with the Glasgow Coma Scale. It quantifies responsiveness by looking at three areas: eye opening, verbal response, and motor response. Each area has its own scoring range, and when you sum them, you get a total from 3 to 15. A lower total means a deeper unconscious state, while a higher total indicates better consciousness. This tool is valued because it’s quick, repeatable, and tracks changes over time, which is crucial for monitoring injury progression or improvement and guiding urgent management.

Other scales mentioned aren’t designed for this purpose. The APGAR score is used right after birth to assess newborn health, not brain injury consciousness. The Braden scale evaluates risk of developing pressure ulcers in hospitalized patients. The MMSE screens for cognitive impairment and baseline mental status, not the acute level of consciousness in brain injury.
