In field triage, which tool is used to quickly determine a casualty's level of consciousness?

• A. AVPU
• B. Glasgow Coma Scale
• C. FOUR Score
• D. Rancho Los Amigos Scale

Answer: (A)

AVPU is the tool designed for rapid assessment of consciousness in field triage. It classifies responsiveness into four simple categories—Alert, responds to Verbal stimuli, responds to Pain, and Unresponsive—requiring no equipment or complex scoring. This makes it quick and reliable in chaotic prehospital situations, allowing you to separate those who are fully awake and oriented from those who need immediate intervention.

The Glasgow Coma Scale, while detailed, needs assessing eye opening, verbal, and motor responses and then calculating a score, which can be time-consuming and affected by factors like intubation or sedation. The FOUR Score adds more detail but is still relatively complex for field use and is more typical in hospital settings. The Rancho Los Amigos Scale focuses on cognitive functioning and rehab progression after brain injury, not on immediate consciousness, so it isn’t suited for rapid triage decisions.
