Incorrect. Synchronized cardioversion with 50-100 J is effective for narrow, regular tachycardias that are unstable.

Incorrect. Defibrillation attempts should be separated by 2-minute CPR cycles to ensure effective perfusion and rhythm evaluation.

Incorrect. Rhythm checks should be performed every 2 minutes during CPR, coinciding with compressor role switches.

Incorrect. Naloxone reverses opioid-induced respiratory depression, restoring normal respiratory function.

Incorrect. A PETCO2 level greater than 10 mmHg indicates that chest compressions are generating adequate blood flow.

Incorrect. Amiodarone is the preferred antiarrhythmic for stabilizing wide-complex tachycardia in stable patients.

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

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

Incorrect. Synchronized cardioversion is the treatment of choice for unstable ventricular tachycardia with a pulse.

Incorrect. Compressions at 1/3 the depth of the chest ensure adequate perfusion while minimizing injury to internal organs.

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

Incorrect. Oxygenation and ventilation should be closely monitored to prevent hypoxia and hyperoxia.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and administration of epinephrine.
