What is the first step in assessing a patient at the scene?

The initial step in assessing a patient at a scene is to check for responsiveness. This assessment is crucial because it helps to quickly evaluate the patient's level of consciousness and overall condition. By checking responsiveness, a first responder can determine whether the patient is conscious and able to follow commands, which provides insight into their neurological status.

This step is vital as it guides the responder in deciding what actions to take next. If the patient is unresponsive, it indicates potential life-threatening issues requiring immediate medical intervention. Assessing responsiveness also allows responders to gather critical information about the patient's needs, facilitating calls for additional support if necessary.

The other potential actions, such as calling for medical support, performing a head-to-toe assessment, or administering first aid, typically follow the initial responsiveness check. These subsequent actions are informed by the findings from the responsiveness assessment, ensuring that responders prioritize the patient's health in an effective, systematic way.
