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

Incorrect. Atropine should not exceed a total dose of 3 mg when treating symptomatic bradycardia in adults.

Incorrect. Magnesium sulfate is the first-line treatment for torsades de pointes as it stabilizes the myocardium.

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

Incorrect. Immediate defibrillation is critical for shockable rhythms like ventricular fibrillation and pulseless VT.

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

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

Incorrect. Pediatric defibrillation begins at 2 J/kg for the first shock and increases as necessary for subsequent shocks.

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

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

Incorrect. Indicates effective chest compressions and blood circulation during resuscitation.

Incorrect. Hypothermia is a potentially reversible cause of cardiac arrest and should be addressed during resuscitation.

Incorrect. Early stabilization of blood pressure and oxygenation is critical to preventing further cardiac arrest after ROSC.

Incorrect. Adult defibrillation with a biphasic defibrillator typically starts at 120-200 J, not 360 J, depending on the manufacturer's guidelines.

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

Incorrect. TTM is used to reduce neurological injury post-ROSC by maintaining a core temperature of 32-36°C.

Incorrect. Maintaining oxygen saturation at 92-96% avoids hypoxia while preventing hyperoxia, which can cause further tissue damage.

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

Incorrect. With an advanced airway, compressions continue uninterrupted while ventilation is provided at a rate of 10 breaths per minute.

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

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

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

Incorrect. Maintaining this range prevents hypoxia while minimizing the risks of hyperoxia and oxidative injury.

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

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