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

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

Incorrect. Epinephrine is the first-line drug for VF, with amiodarone as the preferred antiarrhythmic for refractory cases.

Incorrect. High-quality CPR should be resumed immediately after a shock to maintain perfusion and increase the likelihood of ROSC.

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

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

Incorrect. Rotating team roles every 2 minutes prevents fatigue, ensuring consistent delivery of high-quality chest compressions.

Incorrect. High-quality CPR is the primary intervention for PEA, followed by epinephrine administration and addressing reversible causes.

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

Incorrect. For biphasic defibrillators, 120-200 J is the recommended energy range for VF.

Incorrect. Immediate defibrillation is the most effective intervention for a witnessed cardiac arrest in VF.

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

Incorrect. The target oxygen saturation is 92-96% to avoid hyperoxia, which can contribute to oxidative injury.

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

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J, restoring organized electrical activity.

Incorrect. Atrial flutter presents as a sawtooth pattern on the ECG and requires rate control or cardioversion depending on stability.

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

Incorrect. Adenosine is contraindicated in unstable patients; synchronized cardioversion is the treatment of choice in such cases.

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

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

Incorrect. Magnesium sulfate stabilizes the cardiac membrane and is the drug of choice for treating torsades de pointes.

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

Incorrect. Pulse checks are performed every 2 minutes during rhythm assessments to evaluate the effectiveness of resuscitation.

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation in pediatric patients.

Incorrect. Hypoxia is the most frequent reversible cause of PEA and should be addressed immediately with oxygenation and ventilation.

Incorrect. Ventilations are delivered every 6-8 seconds to provide oxygenation without interrupting chest compressions.

Incorrect. Synchronized cardioversion is used for unstable atrial fibrillation to restore organized electrical activity.

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