Incorrect. Pediatric defibrillation starts at 2 J/kg and may increase to 4 J/kg for subsequent shocks if VF persists.

Incorrect. PETCO2 readings above 10 mmHg during CPR indicate adequate chest compressions and cardiac output.

Incorrect. A compression fraction >80% ensures that the majority of CPR time is spent delivering chest compressions to improve outcomes.

Incorrect. Pulseless VT is treated with defibrillation, while synchronized cardioversion is reserved for tachyarrhythmias with a pulse.

Incorrect. These shockable rhythms require immediate defibrillation to restore a perfusing rhythm.

Incorrect. Two minutes of CPR (about 5 cycles of 30 compressions and 2 breaths) should be performed before reassessing the rhythm.

Incorrect. Amiodarone 300 mg IV/IO is administered after defibrillation and epinephrine to treat refractory VF or pulseless VT.

Incorrect. Delivering 10 breaths per minute ensures adequate oxygenation without causing hyperventilation.

Incorrect. Placing hands on the lower half of the sternum ensures effective chest compressions without damaging other structures.

Incorrect. Pediatric defibrillation begins at 2 J/kg for the first shock and increases as necessary for subsequent shocks.

Incorrect. Atropine is the first-line drug for treating symptomatic bradycardia by increasing heart rate through vagal inhibition.

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

Incorrect. Maintaining oxygen saturation at 92-96% prevents hypoxia and avoids complications associated with hyperoxia.

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

Incorrect. Oxygen saturation should be maintained at 92-96% to avoid hypoxia and reduce the risk of hyperoxia and oxidative stress.

Incorrect. PETCO2 monitoring provides continuous feedback on the quality of chest compressions and the effectiveness of resuscitation.

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

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

Incorrect. With an advanced airway in place, uninterrupted compressions improve blood flow while ventilation is delivered separately.

Incorrect. Magnesium sulfate is administered to stabilize the myocardium and terminate torsades de pointes.

Incorrect. Ventricular fibrillation is the most common cause of sudden cardiac arrest and requires immediate defibrillation.

Incorrect. Ventilations are delivered every 6-8 seconds to provide oxygenation without interrupting chest compressions.

Incorrect. The maximum dose of atropine for bradycardia is 3 mg, with doses given at 0.5 mg intervals every 3-5 minutes.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and must be corrected to restore spontaneous circulation.

Incorrect. Epinephrine is the first-line drug for VF, with amiodarone as the preferred antiarrhythmic for refractory cases.

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

Incorrect. Ventricular fibrillation (VF) is a shockable rhythm and requires immediate defibrillation to restore an organized rhythm.

Incorrect. Magnesium sulfate stabilizes cardiac myocytes and is the drug of choice for treating torsades de pointes.

Incorrect. Atropine is given at a dose of 0.5 mg every 3-5 minutes during bradycardia, up to a maximum dose of 3 mg.

Incorrect. PETCO2 monitoring helps assess the effectiveness of both ventilation and chest compressions in real-time during CPR.
