Incorrect. Rescuers should switch roles every 2 minutes to maintain high-quality chest compressions and prevent fatigue.

Incorrect. PEA is treated with CPR, epinephrine, and identifying reversible causes to restore organized electrical activity.

Incorrect. Hypovolemia is a reversible cause of cardiac arrest that can be treated with fluid resuscitation to restore circulation.

Incorrect. ROSC signifies the resumption of spontaneous cardiac activity with effective circulation, improving patient survival.

Incorrect. Adenosine is administered as a rapid IV push at an initial dose of 6 mg to terminate stable SVT.

Incorrect. Atropine doses should not exceed 3 mg during bradycardia management to avoid adverse effects.

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating reentrant arrhythmias causing narrow-complex tachycardia.

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating narrow-complex SVT caused by reentrant circuits.
