When you check the first aid ABCs, you are assessing a victim's:

• A. Airway, breathing, and circulation
• B. Arms, back, and chest
• C. Alcohol level, blood pressure, and heart rate
• D. Breathing, pulse, and temperature

Answer: (A)

The main idea is that first aid ABCs focus on the most immediate life-support priorities: Airway, Breathing, and Circulation. You first make sure the airway is open so air can reach the lungs, using a head-tilt/chin-lift or jaw-thrust if spinal injury is possible. Next, you assess whether the person is breathing normally; if not, you provide rescue breaths if you’re trained and then call for help. Finally, you check circulation by feeling for a pulse and looking for signs that blood is circulating to vital organs; if there’s no pulse or if bleeding is life-threatening, you initiate CPR and control the bleeding as needed. These steps distinguish the ABCs from the other options, which reference body parts or measurements not part of the standard sequence. Airway, Breathing, and Circulation is the correct framework.
