What is the third step in adult CPR for a single rescuer?

• A. Alone- leave, activate EMS, and get AED
• B. Check responsiveness and breathing
• C. Begin chest compressions
• D. Provide two breaths

Answer: (A)

The main idea here is that in a single-rescuer scenario, getting advanced help and the defibrillator as quickly as possible becomes the next priority after you determine the person is unresponsive. Approaching CPR with speed to EMS activation and an AED on the way can dramatically improve outcomes, because defibrillation is time-critical in adult cardiac arrest. So, the third step is to leave the immediate area briefly to activate the EMS system and to fetch an AED, ensuring professional help and the device will be ready when you return. Once EMS is on the way and the AED is available, you resume CPR immediately, delivering high-quality chest compressions and, if trained, rescue breaths. The earlier steps—checking responsiveness and breathing—remain essential, and starting compressions or breaths comes after arranging for emergency support and defibrillation resources.
