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

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

Incorrect. Compressing 2-2.4 inches ensures effective perfusion during adult CPR while minimizing the risk of injury.

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

Incorrect. Adenosine is administered as a 6 mg rapid IV push, followed by a saline flush, to terminate reentrant arrhythmias.

Incorrect. Activating EMS ensures help is on the way while you assess and initiate resuscitation.

Incorrect. Adequate oxygenation and ventilation are critical to preventing hypoxia or hyperoxia after ROSC.

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

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

Incorrect. Adenosine is the first-line drug for treating narrow-complex SVT by slowing conduction through the AV node.

Incorrect. Providing 6-8 breaths per minute prevents hyperventilation and maintains adequate oxygenation during CPR with an advanced airway.

Incorrect. Hypoxia is a reversible cause of PEA; it must be treated immediately with oxygenation and ventilation.

Incorrect. High-quality CPR is the primary treatment for asystole, along with epinephrine and addressing reversible causes.

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

Incorrect. Compressing to one-third the depth of the chest ensures adequate perfusion while minimizing the risk of injury.

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

Incorrect. The two-thumb encircling technique provides high-quality compressions for infants during CPR.

Incorrect. Adenosine is used to terminate stable narrow-complex tachycardia by slowing AV node conduction.

Incorrect. Epinephrine at 0.01 mg/kg is administered every 3-5 minutes during pediatric cardiac arrest to improve coronary perfusion.

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

Incorrect. Pulse checks should be limited to 10 seconds to minimize interruptions in chest compressions.
