The highest priority in the ABCs during an emergency is?

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

Answer: (A)

Securing a patent airway is the highest priority because without an open airway, ventilation and oxygen delivery cannot occur, and brain and other organs deteriorate rapidly. In the ABC sequence, airway comes first, then breathing, then circulation; once the airway is protected, you assess breathing and provide ventilation as needed, followed by circulation with chest compressions if there’s no pulse. Disability is important for quick neurologic status, but it is addressed after airway and breathing and circulation have been started since life-threatening airway compromise takes precedence.
