What is the FIRST THING you should do when coming upon a person who might need first aid?

The most appropriate initial action when encountering a person who may require first aid is to assess the situation and determine if the person is responsive. By asking, "Are you OK?" you perform a critical step in assessing the victim’s condition and establishing communication. This inquiry not only gives you insight into the individual's state of consciousness but also encourages them to respond, which is essential for understanding their specific needs.

Assessing responsiveness is vital because it helps you gauge the urgency of the situation and decide on the next steps, such as calling for medical assistance if the person does not respond or is in distress. It also lays the groundwork for any further assessment, such as checking for a pulse or airway clearance, which are more involved procedures that would come after determining if the victim is conscious.

In contrast, immediately clearing the airway or checking for a pulse may be appropriate in certain specific emergencies but should not be the initial action without first addressing the person's responsiveness. Performing rescue breathing is a critical skill for specific scenarios but is only relevant if the individual is unresponsive and not breathing. Therefore, starting with a simple question allows for a more thorough assessment and appropriate response.
