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

Incorrect. The most reliable method to confirm and monitor placement by measuring exhaled CO?.

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

Incorrect. A rate of 100-120 compressions per minute optimizes perfusion without compromising cardiac filling.

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

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

Incorrect. Naloxone is used to reverse opioid overdose, restoring respiratory effort in patients with respiratory depression.

Incorrect. Atropine blocks vagal stimulation, increasing heart rate in cases of symptomatic bradycardia.

Incorrect. Synchronized cardioversion is used for unstable atrial fibrillation to restore organized electrical activity.

Incorrect. PETCO2 monitoring provides real-time feedback on ventilation and the effectiveness of 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. Epinephrine is administered every 3-5 minutes during cardiac arrest to maximize coronary and cerebral perfusion.

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

Incorrect. Pulseless VT is treated with defibrillation, not atropine. Atropine is used for symptomatic bradycardia.

Incorrect. PEA is not treated with adenosine; it is managed with CPR, epinephrine, and identifying and treating reversible causes.

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation without risking incomplete recoil or excessive fatigue.

Incorrect. Maintaining a compression fraction above 80% ensures adequate blood flow during resuscitation.

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

Incorrect. Amiodarone is used to stabilize wide-complex tachycardias in stable patients to prevent deterioration into cardiac arrest.

Incorrect. Naloxone is only used in cases of suspected opioid overdose and is not universally administered in cardiac arrest.

Incorrect. Post-ROSC care focuses on optimizing oxygenation, ventilation, and hemodynamic stability to prevent further organ damage.

Incorrect. Hypovolemia is a reversible cause of cardiac arrest and should be corrected with fluid resuscitation.

Incorrect. Pediatric defibrillation begins at 2 J/kg and increases to 4 J/kg for subsequent shocks if needed.

Incorrect. First-line treatment to block vagal stimulation and increase heart rate.

Incorrect. Ventilations should be provided at a controlled rate of 6-8 breaths per minute to prevent hyperventilation.

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

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

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

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

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

Incorrect. The compression-to-ventilation ratio for single-rescuer infant CPR is 30:2, ensuring sufficient oxygenation and circulation.

Incorrect. Interruptions in chest compressions should be minimized to less than 10 seconds to maintain adequate perfusion.

Incorrect. Optimal for maintaining adequate circulation without risking poor perfusion due to excessive speed.
