What is the difference between "confirmation ON" and "confirmation OFF" in shock delivery?

• A. Confirmation ON: uncommitted shock
• B. Confirmation ON: committed shock
• C. Confirmation OFF: uncommitted shock
• D. Confirmation OFF: committed shock

Answer: (A)

The key idea is how requiring user confirmation changes whether a shock is delivered automatically or only after explicit approval. When confirmation is on, the device analyzes the rhythm and signals a shock, but it does not fire it until you confirm. That means the shock is not yet going to happen—the system is in an uncommitted state until you press confirm. This safety step prevents accidental or premature shocks. If confirmation is off, the device proceeds to deliver the shock automatically once the rhythm is deemed shockable. That is a committed shock, because the device has moved forward to delivery without awaiting your explicit approval. So the correct pairing is that Confirmation ON corresponds to an uncommitted shock, and the other combinations don’t fit the way confirmation status changes the delivery commitment.
