Which term describes the energy delivery when charging completes prior to a shock?

• A. Rescue shock
• B. ATP
• C. VT1
• D. VT2

Answer: (A)

The main idea is about delivering a defibrillation shock during CPR after the device has been charged. When the defibrillator is precharged so that the energy is ready and can be released immediately after a shockable rhythm is identified, that instant shock is called a rescue shock. It highlights the life-saving intention of delivering the energy as soon as a shockable rhythm is confirmed, without delaying treatment.

ATP is unrelated here—it's the cellular energy molecule, not a term for a defibrillation event. VT1 and VT2 aren’t used to label the timing of energy delivery in resuscitation; they refer to other aspects of ventricular tachyarrhythmias or thresholds, not the specific act of a precharged shock delivered during CPR.
