Incorrect. TTM helps reduce neurological injury after ROSC by maintaining a target temperature between 32-36°C.

Incorrect. A rate of 100-120 compressions per minute optimizes perfusion without compromising cardiac filling.

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

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

Incorrect. Hypovolemia is a reversible cause of PEA and can be treated with rapid fluid resuscitation.

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

Incorrect. Ventilations should be provided at a controlled rate of 6-8 breaths per minute to prevent hyperventilation.

Incorrect. Epinephrine is repeated every 3-5 minutes during cardiac arrest to enhance perfusion pressure.

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

Incorrect. Pediatric defibrillation starts at 2 J/kg and may increase to 4 J/kg for subsequent shocks if VF persists.

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

Incorrect. Hypoxia is a reversible cause of PEA; it must be treated immediately with oxygenation and ventilation.

Incorrect. Asystole is a non-shockable rhythm and is treated with high-quality CPR and epinephrine administration.

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

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

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

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

Incorrect. Epinephrine is dosed at 0.01 mg/kg IV/IO during pediatric cardiac arrest to improve coronary and cerebral perfusion.

Incorrect. Pediatric defibrillation starts at 2 J/kg, increasing to 4 J/kg for subsequent shocks if needed.

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

Incorrect. ROSC stands for "Return of Spontaneous Circulation," indicating the resumption of a perfusing rhythm.

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

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

Incorrect. VF is a shockable rhythm requiring immediate defibrillation to restore an organized cardiac rhythm.

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

Incorrect. Asystole is not a shockable rhythm; it is treated with high-quality CPR and epinephrine.

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

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

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

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

Incorrect. Providing 6-8 breaths per minute prevents hyperventilation and maintains adequate oxygenation during CPR with an advanced airway.

Incorrect. Adenosine is administered as a rapid IV push to terminate SVT in pediatric patients, followed by a saline flush.

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

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

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

Incorrect. Hypovolemia is a reversible cause of cardiac arrest and should be corrected with fluid resuscitation.

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

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