Basic Life Support (BLS) Renewal Practice Exam - Prep Guide and Practice Test

After an Automated External Defibrillator (AED) delivers a shock, the next step is to resume CPR, starting with chest compressions. This is crucial because the shock may help restore a normal heart rhythm, but the victim often remains in need of immediate life support until effective circulation is re-established.

Continuing with CPR ensures that blood is circulated to the brain and vital organs, which is essential for maintaining their function. The compression helps provide the necessary pressure to circulate oxygenated blood, enhancing the patient's chances of survival. Additionally, one should wait until the AED re-analyzes the heart rhythm before performing chest compressions again, but the priority right after a shock is to re-initiate CPR to maximize the chance of survival.

The other actions, while important in the overall management of a cardiac arrest, are not appropriate immediately after delivering a shock. Checking for responsiveness or monitoring breathing takes time and does not address the urgent need to maintain blood flow. Waiting for further instructions would stall critical lifesaving efforts that can be more efficiently handled immediately through CPR.
