What is the first action Susan should take after ensuring the scene is safe for Noah?

The first action Susan should take after confirming the scene is safe is to check Noah for responsiveness and breathing. This step is crucial because it helps Susan assess the current condition of Noah. By checking for responsiveness, she can determine if he is conscious or unconscious and if he can respond to her voice or touch. Following that, checking for breathing allows her to identify whether Noah is breathing normally or if he is experiencing a medical emergency that may require further intervention.

This initial assessment guides subsequent actions. If Noah is unresponsive and not breathing, it would dictate the need to call for emergency assistance and possibly start CPR. Without determining responsiveness and breathing first, she may not proceed correctly based on the severity of his condition. It's important to approach the situation methodically to ensure the appropriate response.
