Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.

Incorrect. ROSC signifies the resumption of spontaneous cardiac activity with effective circulation, improving patient survival.

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

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

Incorrect. Maintaining oxygen saturation at 92-96% avoids hypoxia while preventing hyperoxia, which can cause further tissue damage.

Incorrect. A 15:2 ratio is used during pediatric CPR with two rescuers to optimize ventilation and circulation.

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

Incorrect. Defibrillation is the primary treatment for pulseless VT, aiming to restore organized cardiac activity.

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

Incorrect. Pulseless VT is a shockable rhythm that requires immediate defibrillation to restore a perfusing rhythm.

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

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating reentrant arrhythmias causing narrow-complex tachycardia.

Incorrect. Assessing responsiveness is the first step in determining the need for CPR or other interventions in the BLS survey.
