What are the primary components of a rapid on-field assessment (ABCs) in athletic injury management?

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

Answer: (A)

The rapid on-field assessment follows a clear priority: Airway, Breathing, Circulation. You start by ensuring the airway is open and protected because if the airway is blocked, air cannot reach the lungs and the rest of the assessment can’t be trusted. Once the airway is secure, you assess breathing to determine if the athlete is ventilating adequately and to decide if rescue breaths or other ventilation support are needed. Only after airway and breathing are addressed do you evaluate circulation to identify and control life-threatening bleeding and ensure perfusion.

The other sequences don’t fit this immediate life-support order. Reordering to check circulation before breathing risks missing failure to ventilate or an airway obstruction; starting with breathing assumes the airway is already clear, which isn’t guaranteed; and swapping in disability shifts focus away from immediate airway, breathing, and perfusion priorities.
