Incorrect. High-quality CPR should be resumed immediately after defibrillation to maintain perfusion and increase chances of ROSC.

Incorrect. PEA is not a shockable rhythm; it is treated with CPR and addressing reversible causes such as hypoxia or hypovolemia.

Incorrect. Epinephrine is given first in VF during cardiac arrest, followed by amiodarone as an antiarrhythmic after defibrillation attempts.

Incorrect. Switching every 2 minutes reduces rescuer fatigue and ensures high-quality chest compressions.

Incorrect. Atrial flutter presents as a sawtooth pattern on the ECG and requires rate control or cardioversion depending on stability.
