Incorrect. Synchronized cardioversion restores organized cardiac activity in unstable VT with a pulse, preventing progression to VF.

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

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

Incorrect. VF is a shockable rhythm, and defibrillation is the most effective intervention to restore a normal rhythm.

Incorrect. Two rescuers are needed to maintain high-quality CPR with an advanced airway: one for compressions and one for ventilation.

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

Incorrect. Prevents progression to cardiac arrest by restoring a normal rhythm.

Incorrect. Shouting for help ensures additional resources and a defibrillator are quickly available.

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

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

Incorrect. Optimal for maintaining adequate circulation without risking poor perfusion due to excessive speed.

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

Incorrect. PETCO2 monitoring provides real-time feedback on chest compressions and the effectiveness of CPR.

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

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

Incorrect. This rate ensures effective circulation without causing inadequate ventricular filling.

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

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

Incorrect. Ventricular fibrillation presents as a disorganized rhythm that requires immediate defibrillation.

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

Incorrect. Dopamine is used to improve heart rate and contractility in bradycardia unresponsive to atropine.

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

Incorrect. Adenosine is used for narrow-complex SVT, not wide-complex tachycardia, which is typically treated with amiodarone.

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

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

Incorrect. The correct dose of epinephrine for pediatric cardiac arrest is 0.01 mg/kg IV/IO, not 1 mg/kg.

Incorrect. PEA is not a shockable rhythm; it is treated with CPR and addressing reversible causes such as hypoxia or hypovolemia.

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

Incorrect. For adult CPR, the ratio ensures adequate perfusion and oxygenation when no advanced airway is in place.

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

Incorrect. With an advanced airway in place, compressions should continue uninterrupted while providing 10 breaths per minute.

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

Incorrect. These shockable rhythms require immediate defibrillation to restore a perfusing rhythm.

Incorrect. Delivering 10 breaths per minute ensures adequate oxygenation without causing hyperventilation.

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

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

Incorrect. Oxygenation and ventilation should be optimized to avoid hypoxia or hyperoxia during post-cardiac arrest care.

Incorrect. Adenosine is administered as a 0.1 mg/kg rapid IV push for pediatric SVT, followed by a saline flush.
