ACPR fraction should be kept above 60%, requiring pre-shock pauses of no more than 10 seconds.
BThe ratio of compressions to ventilations must remain 30:2 during defibrillator charging.
CThe compression rate must not fall below 100/min during any pause.
DPost-shock pauses longer than 15 seconds require documentation only, not correction.
✓ Correct answer: A. CPR fraction should be kept above 60%, requiring pre-shock pauses of no more than 10 seconds.AHA guidelines recommend minimizing all peri-shock pauses to under 10 seconds and maintaining a CPR fraction (proportion of resuscitation time with compressions) greater than 60% to optimize perfusion pressure.
