What should be done first when you encounter an unresponsive individual?

When encountering an unresponsive individual, the first step is to check for responsiveness. This step is crucial because it helps to assess the individual's level of consciousness and determine if they require immediate medical intervention. By checking for responsiveness, you can confirm whether the person is awake and aware, or if they need urgent assistance.

Only once you establish that the individual is unresponsive can you proceed with further actions, such as calling for help or checking for breathing. This initial step is fundamental in guiding your next course of action and ensures that you are responding appropriately to the situation.
