Incorrect. Prompt defibrillation within 30 seconds of witnessed VF arrest improves the chance of restoring a perfusing rhythm.

Incorrect. Synchronized cardioversion restores organized cardiac activity in unstable atrial flutter.

Incorrect. Amiodarone is preferred, but lidocaine is an alternative antiarrhythmic for refractory VF or pulseless VT.

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation in pediatric patients.

Incorrect. Compressing the chest 2-2.4 inches ensures adequate blood flow while minimizing injury risks.

Incorrect. With an advanced airway in place, compressions should continue uninterrupted while providing 10 breaths per minute.

Incorrect. A sudden increase in PETCO2 is a reliable indicator of ROSC, reflecting improved circulation and gas exchange.

Incorrect. A 15:2 ratio ensures efficient oxygenation and circulation in pediatric patients during two-rescuer CPR.

Incorrect. Maintaining a compression fraction of greater than 80% ensures the majority of resuscitation time is spent on compressions.

Incorrect. High-quality CPR is the primary treatment for asystole, along with epinephrine and addressing reversible causes.

Incorrect. Atropine is the first-line treatment for symptomatic bradycardia, increasing the heart rate by blocking vagal stimulation.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be treated with warming measures.

Incorrect. A PETCO2 reading above 10 mmHg indicates adequate chest compressions and cardiac output during CPR.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.

Incorrect. Compressing to a depth of 2-2.4 inches ensures adequate circulation without causing damage to internal organs.

Incorrect. Asystole is a non-shockable rhythm treated with high-quality CPR and epinephrine.

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

Incorrect. Adenosine is used to terminate reentrant arrhythmias in narrow-complex SVT by slowing conduction through the AV node.

Incorrect. Epinephrine is repeated every 3-5 minutes during cardiac arrest to enhance perfusion pressure.

Incorrect. Amiodarone is administered as a 300 mg IV/IO bolus for refractory VF or pulseless VT.
