What should you do if you witness someone collapse and become unresponsive?

Check for pulse immediately
Start administering CPR
Shout for nearby help
Call 911 and wait for help

The correct answer is: Shout for nearby help

In a situation where you witness someone collapse and become unresponsive, the priority is to ensure immediate action is taken. Shouting for nearby help serves a critical purpose: it can quickly mobilize additional assistance, which can be vital in an emergency. This step not only alerts others to the situation but may also bring people who can further assist in calling emergency services or provide support while waiting for the professional responders to arrive. Calling for help does not delay the necessary steps to call 911 or begin CPR but rather enhances the situation by potentially bringing more hands to aid in the emergency response. It's important to remember that while each action taken in a cardiac emergency is crucial, ensuring that help is on the way and that someone else is aware of the situation can significantly improve the outcome for the unresponsive person.
