Final answer:
The correct time to deliver a shock from an AED is after the AED advises a shock, charges, states a 'clear the victim' message, and prompts the user to push the shock button.
Step-by-step explanation:
The correct answer is D. After the AED advises a shock, charges, states a "clear the victim" message, and prompts you to push the shock button.
Automated external defibrillators (AED) are designed to automatically diagnose a patient's heart condition and apply the shock with appropriate energy and waveform. The AED analyzes the patient's heartbeat pattern and determines if a shock is necessary.
Once the AED advises a shock, charges, states a "clear the victim" message, and prompts you to push the shock button, you should deliver the shock.
