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

Incorrect. Epinephrine is administered to increase coronary and cerebral perfusion pressure during cardiac arrest.

Incorrect. Atrial fibrillation is cardioverted starting at 120-200 J in synchronized mode to avoid delivering the shock during ventricular repolarization.

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

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

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J to treat VF or pulseless VT.

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

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

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

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

Incorrect. Immediate CPR is required as asystole is a non-shockable rhythm.

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

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. Lidocaine is an antiarrhythmic drug used as an alternative to amiodarone for VF or pulseless VT.

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

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

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

Incorrect. Maintaining a compression fraction above 80% ensures adequate blood flow during resuscitation.

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

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

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

Incorrect. Minimizes interruptions to maintain blood flow to vital organs.

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

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

Incorrect. Atropine is the first-line treatment for symptomatic bradycardia, increasing the heart rate by blocking vagal stimulation.

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

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

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

Incorrect. Activating EMS ensures help is on the way while you assess and initiate resuscitation.

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

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

Incorrect. Pausing compressions for more than 10 seconds interrupts perfusion and reduces the chances of ROSC.

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

Incorrect. The same compression rate as adults ensures adequate perfusion in pediatric patients during CPR.

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

Incorrect. Rhythm checks are performed every 2 minutes to evaluate for shockable rhythms and assess the need for defibrillation.

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

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

Incorrect. A PETCO2 level greater than 10 mmHg indicates that chest compressions are generating adequate blood flow.

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