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

Incorrect. A compression fraction greater than 80% ensures that most of the resuscitation time is spent performing chest compressions.

Incorrect. Administered every 3-5 minutes to restore circulation by increasing coronary and cerebral perfusion pressure.

Incorrect. Adenosine is administered at 0.1 mg/kg as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

Incorrect. Waveform capnography ensures proper ET tube placement by monitoring exhaled CO? levels.

Incorrect. Prompt defibrillation within 30 seconds of witnessed VF arrest improves the chance of restoring a perfusing rhythm.

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

Incorrect. Provides external electrical stimuli to maintain adequate heart rate when atropine fails.

Incorrect. VF is a shockable rhythm, and defibrillation is the primary treatment to restore an organized rhythm.

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

Incorrect. Switching compressors every 2 minutes reduces rescuer fatigue, ensuring high-quality chest compressions are maintained.

Incorrect. First-line treatment to block vagal stimulation and increase heart rate.

Incorrect. PETCO2 monitoring helps assess the effectiveness of both ventilation and chest compressions in real-time during CPR.

Incorrect. Hypokalemia can cause cardiac arrhythmias and is included in the "H's" of reversible causes of cardiac arrest.

Incorrect. Pulse checks should be limited to 5-10 seconds to minimize interruptions in chest compressions.

Incorrect. Post-ROSC care focuses on stabilizing ventilation and oxygenation to prevent hypoxia or hyperoxia.

Incorrect. The 15:2 ratio improves oxygenation and circulation during high-quality infant CPR performed by two rescuers.

Incorrect. Dopamine is used when atropine is ineffective, improving heart rate and contractility by stimulating beta receptors.

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

Incorrect. IV access is preferred for rapid administration; IO is the alternative if IV access is unavailable.

Incorrect. Calling for help ensures timely assistance and access to advanced resuscitation equipment.

Incorrect. PETCO2 levels greater than 10 mmHg suggest that chest compressions are generating adequate circulation.

Incorrect. Positioning the patient with a slight left tilt prevents aortocaval compression and improves venous return during CPR.

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

Incorrect. IM epinephrine is the first-line treatment for anaphylaxis, administered into the mid-thigh for rapid absorption.

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

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

Incorrect. Maintaining oxygen saturation at 92-96% prevents hypoxia and avoids complications associated with hyperoxia.

Incorrect. Atropine is the first-line drug for treating symptomatic bradycardia by increasing heart rate through vagal inhibition.

Incorrect. Chest compressions for infants should be about 1/3 the depth of the chest, approximately 1.5 inches (4 cm).

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

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

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

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

Incorrect. Magnesium sulfate is administered to stabilize the myocardium and treat torsades de pointes effectively.

Incorrect. Maintaining oxygen saturation within this range ensures adequate oxygenation without the risk of hyperoxia.

Incorrect. PEA is not a shockable rhythm; it is managed with high-quality CPR and addressing the underlying reversible causes.

Incorrect. PEA is not treated with adenosine; it is managed with CPR, epinephrine, and identifying and treating reversible causes.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and must be corrected to restore spontaneous circulation.
