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

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

Incorrect. Pulseless VT is a shockable rhythm requiring immediate defibrillation to restore organized cardiac activity.

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

Incorrect. Epinephrine 1 mg IV/IO is administered every 3-5 minutes during cardiac arrest to improve coronary and cerebral perfusion.

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

Incorrect. Lidocaine is an alternative antiarrhythmic for refractory VF, dosed at 1 mg/kg IV/IO.

Incorrect. PEA is not a shockable rhythm; it is treated with CPR and addressing reversible causes such as hypoxia or hypovolemia.

Incorrect. Delivering 1 breath every 5-6 seconds prevents hypoventilation or hyperventilation.

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

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

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

Incorrect. Defibrillation should be performed immediately after identifying VF, not delayed up to 10 minutes.

Incorrect. Chest compressions are performed to dislodge the obstruction and restore effective ventilation in an unresponsive infant.

Incorrect. The correct compression rate for CPR is 100-120 compressions per minute to optimize perfusion and prevent fatigue.

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

Incorrect. Hypovolemia is a common reversible cause of PEA and should be addressed with rapid fluid resuscitation.

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

Incorrect. Synchronized cardioversion at 100 J is effective for restoring a stable rhythm in unstable ventricular tachycardia.

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

Incorrect. PEA is not a shockable rhythm; it is managed with high-quality CPR and addressing the underlying reversible causes.
