What is the sequence of actions that helps determine what is wrong with a victim?

The sequence of actions to determine what is wrong with a victim typically begins with assessing the scene for safety before approaching the victim. Next, the rescuer checks the victim's responsiveness and performs a primary survey to evaluate airway, breathing, and circulation. If the victim is unresponsive, the rescuer should call for emergency help and provide necessary first aid while monitoring vital signs until professional assistance arrives. Finally, any specific injuries or medical conditions should be identified and communicated to emergency responders.
