question 3 of 3
after recognizing that a person is in cardiac arrest (unresponsive and not breathing), you call 9 - 1 - 1 and send someone to get an aed. what is your next step?
recheck for breathing and responsiveness
ask bystanders what happened and if they know the person
monitor the person until ems personnel arrive and begin their care of the person
start cpr by giving chest compressions and breaths

Explanation:

When a person is in cardiac arrest (unresponsive and not breathing), after calling 9 - 1 - 1 and sending for an AED, the immediate next step is to start CPR. CPR (cardiopulmonary resuscitation) with chest compressions and breaths helps to circulate oxygenated blood to the brain and other vital organs until more advanced medical help (like the arrival of EMS with an AED) is available. Rechecking for breathing and responsiveness is something that can be done during the process of CPR (e.g., after a cycle of compressions and breaths). Asking bystanders details or just monitoring the person without providing active intervention (like CPR) is not the best immediate action as the person is in cardiac arrest and needs circulation support.

Answer:

Start CPR by giving chest compressions and breaths
