Which of the following corresponds to the ABCs in first aid?

The correct choice corresponds to the essential components of first aid, which are critical for assessing and managing an individual's condition during a medical emergency. The ABCs represent:

• Airway: Ensuring that the person's airway is clear and not obstructed is the first priority. If the airway is blocked, oxygen cannot reach the lungs, which can lead to failure to breathe and loss of consciousness.

• Breathing: After confirming that the airway is clear, the next step is to check whether the person is breathing adequately. This involves looking for signs of normal breathing and assessing the quality of breaths.

• Circulation: Finally, evaluating circulation includes checking for pulse and ensuring that blood is circulating effectively throughout the body. This step is crucial for determining if the heart is functioning properly and if there is sufficient blood flow, which is vital for sustaining life.

These three steps form the foundational protocol for first responders and caregivers when addressing emergencies, making this choice the correct representation of the ABCs in first aid. The understanding and application of this sequence can significantly improve the chances of survival in critical situations.
