See the questions first
Real items, with the answer marked and the reason written out — the same format as all 124.
An AED arrives while you are performing CPR on an adult in cardiac arrest. What should you do?
Why: The AED is used as soon as it arrives, with compressions continuing until the pads are on and pausing only for analysis and the shock.
At what rate should chest compressions be delivered to an adult in cardiac arrest?
Why: Current AHA guidelines specify a compression rate of 100 to 120 per minute for all ages. Slower than 100 does not generate adequate perfusion, while faster than 120 shortens the recoil phase so the heart cannot refill, which paradoxically lowers the blood delivered per compression.
