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

Incorrect. Hypoxia is one of the most common reversible causes of PEA and is addressed with high-quality oxygenation during resuscitation.

Incorrect. Pulseless VT is treated with defibrillation, while synchronized cardioversion is reserved for tachyarrhythmias with a pulse.

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

Incorrect. Amiodarone 300 mg IV/IO is administered after defibrillation and epinephrine to treat refractory VF or pulseless VT.

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

Incorrect. Atropine is given at a dose of 0.5 mg every 3-5 minutes during bradycardia, up to a maximum dose of 3 mg.

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

Incorrect. Early defibrillation is critical for survival, especially in shockable rhythms like VF/VT.

Incorrect. Synchronized cardioversion is used to terminate unstable SVT by restoring normal electrical activity in the heart.

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

Incorrect. Placing hands on the lower half of the sternum ensures effective chest compressions without damaging other structures.

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

Incorrect. Amiodarone is used after defibrillation and epinephrine for refractory VF to stabilize the myocardium.

Incorrect. Magnesium sulfate is used to treat torsades de pointes but is not the first-line drug for VF, where epinephrine is prioritized.

Incorrect. Maintains vasoconstriction, improving blood flow to vital organs during resuscitation.

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

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

Incorrect. Pulseless VT is treated with defibrillation, not atropine. Atropine is used for symptomatic bradycardia.

Incorrect. A left lateral tilt prevents aortocaval compression, improving venous return and cardiac output during resuscitation.

Incorrect. Early defibrillation within 30 seconds of a witnessed VF arrest increases survival rates significantly.

Incorrect. Minimizing interruptions to less than 10 seconds preserves perfusion and improves resuscitation outcomes.

Incorrect. Ventricular fibrillation (VF) is a shockable rhythm and requires immediate defibrillation to restore an organized rhythm.

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

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

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

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

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

Incorrect. Pediatric defibrillation starts at 2 J/kg to safely deliver an effective shock without causing harm.

Incorrect. PEA is treated with CPR and epinephrine, as defibrillation is ineffective for non-shockable rhythms.

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

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

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and epinephrine to optimize perfusion.

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

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

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

Incorrect. Defibrillation should be performed immediately after identifying VF, not delayed up to 10 minutes.

Incorrect. Oxygen levels should be monitored and optimized to maintain saturation within the target range of 92-96%.

Incorrect. Interruptions in chest compressions should not exceed 10 seconds to maintain adequate perfusion to vital organs.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and administration of epinephrine.

Incorrect. Administered via rapid IV push, followed by a saline flush to terminate reentrant arrhythmias.

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

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

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

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

Incorrect. Avoid delays to minimize interruptions in chest compressions and maintain perfusion.

Incorrect. IO access provides a reliable alternative for rapid drug delivery during resuscitation when IV access cannot be obtained.

Incorrect. Epinephrine at 0.01 mg/kg IV/IO is administered every 3-5 minutes to enhance coronary and cerebral perfusion in children.

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

Incorrect. Synchronized cardioversion is used to restore a normal rhythm in unstable atrial fibrillation.

Incorrect. While hypoglycemia can cause critical symptoms, it is not included in the H's and T's of reversible causes of cardiac arrest.

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

Incorrect. Compressions at 1/3 the depth of the chest ensure adequate perfusion while minimizing injury to internal organs.

Incorrect. VF is a shockable rhythm, and immediate defibrillation is the most effective treatment.

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

Incorrect. Two minutes of CPR (about 5 cycles of 30 compressions and 2 breaths) should be performed before reassessing the rhythm.
