This "new" standard has been the standard for 5ish years....there shouldn't be any confusion to this. Maybe drug dosages yes, because local protocols vary, but confusion about what to do after a shock!?!?!?
Only two people answered incorrectly, but even the ones who got it right didn't seem that confident.
THE MORE RARELY WE USE A SKILL, THE MORE WE SHOULD PRACTICE IT. I'm sure there's some skills I'm guilty of not practicing enough, too...
Compressions until last minute possible (including during charging unless it's a rapid charge unit...and even then you can still do it), shock, continue CPR immediately. The interruption in compressions should be MINIMAL.
I try to train myself that the phrases "no pulse" "charging" and "shock delivered" should always be followed with "continue CPR" (or a variation of it). So the phrases roll off your tongue as one sentence to minimize delays in resuming compressions.
