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

Incorrect. Immediate defibrillation is critical for shockable rhythms like ventricular fibrillation and pulseless VT.

Incorrect. Administered via rapid IV push, followed by a saline flush to terminate reentrant arrhythmias.

Incorrect. VF is a shockable rhythm, and immediate defibrillation is the most effective treatment.

Incorrect. A supine position ensures proper electrode placement and effective delivery of defibrillation shocks.

Incorrect. Amiodarone is used after defibrillation and epinephrine for refractory VF to stabilize the myocardium.

Incorrect. Hypothermia is a potentially reversible cause of cardiac arrest and should be addressed during resuscitation.

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

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

Incorrect. Epinephrine at 0.01 mg/kg IV/IO is administered every 3-5 minutes to enhance coronary and cerebral perfusion in children.

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

Incorrect. With an advanced airway, compressions continue uninterrupted while ventilation is provided at a rate of 10 breaths per minute.

Incorrect. Adenosine is administered as a 6 mg rapid IV push, followed by a saline flush, to terminate reentrant arrhythmias.

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

Incorrect. CPR should be resumed immediately after defibrillation to maintain perfusion and increase the likelihood of ROSC.

Incorrect. Pulse checks during CPR should not exceed 10 seconds to minimize interruptions in chest compressions.

Incorrect. A compression fraction >80% is required to maximize perfusion and improve survival rates during high-quality CPR.

Incorrect. The target oxygen saturation is 92-96% to avoid hyperoxia, which can contribute to oxidative injury.

Incorrect. Hypokalemia can cause cardiac arrhythmias and is included in the "H's" of reversible causes of cardiac arrest.

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

Incorrect. Epinephrine is given at a dose of 1 mg IV/IO every 3-5 minutes during adult cardiac arrest to improve perfusion.

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

Incorrect. Pediatric defibrillation starts with 2 J/kg, increasing to 4 J/kg for subsequent shocks if needed.

Incorrect. IO access provides a reliable alternative for rapid drug delivery during resuscitation when IV access cannot be obtained.

Incorrect. Epinephrine is administered every 3-5 minutes during cardiac arrest to maximize coronary and cerebral perfusion.

Incorrect. A 30:2 ratio ensures sufficient oxygenation and circulation in adults during CPR without an advanced airway.

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

Incorrect. VF is a shockable rhythm, and defibrillation is the most effective intervention to restore a normal rhythm.

Incorrect. The compression fraction should be greater than 80% to maximize perfusion during CPR.

Incorrect. Post-ROSC care focuses on maintaining oxygenation and avoiding hypoxia or hyperoxia to protect organ function.

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

Incorrect. Ventilations are delivered at a rate of 6-8 breaths per minute to prevent hyperventilation.

Incorrect. Prevents progression to cardiac arrest by restoring a normal rhythm.

Incorrect. Dopamine is used to improve heart rate and contractility in bradycardia unresponsive to atropine.

Incorrect. The same compression rate as adults ensures adequate perfusion in pediatric patients during CPR.

Incorrect. Delivering 6-8 breaths per minute minimizes interruptions in chest compressions and prevents hyperventilation.

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

Incorrect. The correct dose of epinephrine for pediatric cardiac arrest is 0.01 mg/kg IV/IO, not 1 mg/kg.

Incorrect. The initial dose of adenosine for stable SVT in adults is 6 mg IV, followed by 12 mg if needed for subsequent doses.
