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

Incorrect. Pausing compressions for more than 10 seconds interrupts perfusion and reduces the chances of ROSC.

Incorrect. Adenosine is the first-line drug for stable SVT, while synchronized cardioversion is used for unstable SVT.

Incorrect. The jaw thrust maneuver opens the airway without manipulating the cervical spine, protecting against spinal cord injury.

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

Incorrect. Adenosine is used for narrow-complex SVT, not wide-complex tachycardia, which is typically treated with amiodarone.

Incorrect. Thrombosis (pulmonary or coronary) is a reversible cause of cardiac arrest and should be addressed immediately.

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

Incorrect. Delivers an electrical shock to depolarize the heart and restore a normal rhythm.

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

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

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

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

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

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

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

Incorrect. Rhythm checks are performed every 2 minutes during pauses in CPR to evaluate for shockable rhythms.

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J to treat VF or pulseless VT.

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

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

Incorrect. Providing 6-8 breaths per minute ensures adequate oxygenation and ventilation without interfering with chest compressions.

Incorrect. The jaw thrust technique opens the airway while minimizing cervical spine movement, reducing the risk of further injury.

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

Incorrect. For unstable narrow, irregular tachycardias, synchronized cardioversion at 120-200 J is recommended.

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