What is the first step a rescuer should take when assessing a victim?

The first step a rescuer should take when assessing a victim is to check responsiveness. This involves determining if the victim is conscious and responsive to stimuli, such as by speaking to them or gently shaking their shoulders. This assessment is crucial because it helps the rescuer to quickly understand the severity of the situation. If the victim is responsive, the rescuer can gather more information about their condition, while if they are unresponsive, it signals the need for immediate action, such as calling for emergency help or performing CPR.

When assessing responsiveness, the rescuer can also identify if there are any signs of airway obstruction or need for further intervention, which is essential before proceeding to other steps in the emergency protocol. Identifying the level of responsiveness sets the stage for any required lifesaving measures.
