Basic Life Support for Children and Infants Practice Test

The correct sequence of actions when using an Automated External Defibrillator (AED) is to first attach the pads to the person in need, then allow the device to analyze the heart rhythm, and finally deliver a shock if indicated. This method is effective because having the pads attached before analysis ensures that the AED can accurately assess the patient's condition in real-time.

When the pads are attached, the AED can detect arrhythmias that may require defibrillation, all while minimizing any delays in treatment. Proper pad placement plays a critical role in the device's ability to function effectively, which is why this step comes first.

Following the analysis, if the device determines that a shock is necessary, it will instruct the user to deliver one, thereby providing the immediate and critical intervention that can restore a normal heart rhythm.

Starting CPR and calling emergency services are also vital steps in the chain of survival, but they occur in conjunction with or prior to the AED use, depending on the specific situation. The use of an AED is fundamentally based on the immediate application of the device and obtaining a quick assessment of the heart’s status.
