What is the first step in a hands-on check for an unresponsive individual?

In a hands-on check for an unresponsive individual, starting at the head and moving downward is the correct approach because it allows for a comprehensive assessment of the person's condition while prioritizing areas that may require immediate attention. The head is where the brain, which controls vital functions, is located; therefore, looking there first ensures any critical injuries or conditions, such as severe bleeding or trauma, are identified promptly.

In emergency situations, the head and neck are crucial areas because they can sustain potentially life-threatening injuries that might not be visible elsewhere. By starting the assessment at the head, you can quickly check for responsiveness and circulation before assessing the rest of the body.

This methodical approach enhances the chances of identifying any life-threatening conditions, making it essential to follow it rather than starting at the legs or other areas, which could delay determining the necessary interventions.
