How is Glasgow Coma Scale interpreted in a trauma patient, and what GCS indicates immediate airway protection?

• A. GCS ranges from 3 to 15; a score of 8 or more indicates airway protection is needed
• B. GCS ranges from 3 to 15; a score of 9 or less indicates airway protection is needed
• C. GCS ranges from 3 to 15; a score of 7 or less indicates airway protection is needed
• D. GCS ranges from 3 to 15; a score of 8 or less indicates airway protection is needed

Answer: (D)

Glasgow Coma Scale measures consciousness by adding eye opening, verbal, and motor responses, giving a total that ranges from 3 to 15. In trauma care, lower scores mean deeper loss of consciousness and a higher risk that the patient cannot protect their airway. A GCS of 8 or less indicates the patient cannot reliably maintain airway patency or protect against aspiration, so immediate airway protection is required—typically with endotracheal intubation. Scores above 8 do not automatically mandate airway protection and are assessed in context, but 8 or less is the standard threshold for urgent airway management.
