In single-starred criteria, what do letters A represent?

• A. Alertness, Airway
• B. Breathing, Ventilation
• C. Circulation
• D. Disability

Answer: (A)

The first letter in this assessment scheme groups Alertness and Airway because both are critical gates to oxygen delivery and patient safety in the initial trauma survey. If a patient is not alert, their airway-protective reflexes are compromised, making airway obstruction likely; conversely, if the airway isn’t patent, adequate ventilation and oxygenation can’t occur, which quickly worsens consciousness. So the A cue reminds clinicians to address both neurological status and airway patency together right away. The other steps follow with Breathing/Ventilation, Circulation, and Disability, highlighting the sequential checks after securing airway/alertness.
