Which component is the 'A' in HABC?

Explanation:
The main idea being tested is prioritizing airway management in life-support mnemonics. The letter A stands for Airway, meaning you first check that the person’s airway is open and unobstructed. If the airway is blocked, no amount of breathing support or circulation efforts can deliver oxygen to the body, so securing the airway is the immediate priority. In practice, this means quickly assessing patency, clearing obstructions, and using techniques like a head-tilt-chin-lift or jaw-thrust (if spinal injury is a concern) and suctioning as needed to keep the airway open. The other steps (breathing and circulation) come after you’ve confirmed the airway is clear, because without a functioning airway, those steps can’t be effective. So the component represented by A is Airway.
