Answer :
Final answer:
As a lone rescuer, after calling for help, check the unresponsive victim's airway, breathing, and circulation, and if necessary, begin CPR on stable ground, especially in cases of drowning.
Explanation:
Once you've found an unresponsive victim and shouted for help, ensuring that your call for assistance was heard, the very next thing you should do as a lone rescuer is to check the victim's airway, breathing, and circulation (ABCs) if you are trained to do so. If the victim is not breathing, you will need to begin CPR. However, it's crucial to remember that if the situation involves a drowning victim, the first thing you should do is remove the person from the water to a safe area. Once on stable ground, you can then begin CPR. This order of actions is essential because attempting to perform CPR on a person who is in the water is ineffective.
