A child collapses in front of you. He is unresponsive without a pulse and your phone is dead. What should you do?

The correct response in this scenario emphasizes the urgency and priority of delivering immediate care to the unresponsive child who has no pulse. Starting CPR as soon as possible is critical in this situation, as the child is in cardiac arrest, which requires prompt intervention to maintain blood flow to vital organs.

By running to call 911, you ensure that emergency services are on their way while simultaneously obtaining an AED (automated external defibrillator) if one is available nearby. The AED can greatly increase the child’s chances of survival by analyzing the heart's rhythm and providing a shock if necessary. Once you have the AED, promptly apply it and begin CPR; this combination of efforts is crucial to maximizing oxygen delivery to the brain and other vital organs during cardiac arrest.

Other responses do not prioritize immediate lifesaving actions in the same way. Performing CPR for 2 minutes before calling for help may lead to a delay in getting emergency services to the scene. While CPR is essential, time is of the essence, and any action that prolongs help can be detrimental. Waiting for help to arrive or looking for someone else to call for emergency services unnecessarily delays critical interventions that can save the child's life.
