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

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.

Incorrect. A 30:2 ratio ensures sufficient oxygenation and circulation in adults during CPR without an advanced airway.

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

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

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

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

Incorrect. A single rescuer performs 30 compressions followed by 2 breaths to maximize perfusion and oxygenation in pediatric CPR.

Incorrect. Epinephrine at 1 mg IV every 3-5 minutes is used to enhance perfusion during cardiac arrest.

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

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

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

Incorrect. Epinephrine is given first in VF during cardiac arrest, followed by amiodarone as an antiarrhythmic after defibrillation attempts.

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and must be corrected to restore spontaneous circulation.

Incorrect. Maintaining a compression fraction of greater than 80% ensures the majority of resuscitation time is spent on compressions.

Incorrect. Maximum energy for monophasic defibrillators; for biphasic, follow manufacturer recommendations.

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

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

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. The jaw thrust technique opens the airway while minimizing cervical spine movement, reducing the risk of further injury.

Incorrect. Ventilations are delivered every 6-8 seconds to provide oxygenation without interrupting chest compressions.

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

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

Incorrect. A PETCO2 reading above 10 mmHg indicates adequate chest compressions and cardiac output during CPR.

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

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

Incorrect. CPR is the primary treatment for PEA, along with epinephrine and addressing reversible causes to restore circulation.

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

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

Incorrect. The two-thumb encircling technique provides high-quality compressions for infants during CPR.

Incorrect. Amiodarone is preferred, but lidocaine is an alternative antiarrhythmic for refractory VF or pulseless VT.
