Incorrect. Epinephrine is given to improve perfusion pressure and increase the chance of ROSC in persistent VF.

Incorrect. Providing 6-8 breaths per minute ensures adequate oxygenation and ventilation without interfering with chest compressions.

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

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

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

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

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

Incorrect. First-line treatment to block vagal stimulation and increase heart rate.

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

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

Incorrect. Rhythm checks should be performed every 2 minutes, coinciding with rescuer role switches, to evaluate for shockable rhythms.

Incorrect. Delivering 6-8 breaths per minute minimizes interruptions in chest compressions and prevents hyperventilation.

Incorrect. Epinephrine is given at a dose of 1 mg IV/IO every 3-5 minutes during adult cardiac arrest to improve perfusion.

Incorrect. VF is a shockable rhythm, and defibrillation is the primary treatment to restore an organized rhythm.

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

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

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

Incorrect. PETCO2 monitoring ensures effective ventilation and provides feedback on the quality of chest compressions during CPR.

Incorrect. PEA is treated with CPR, epinephrine, and identifying reversible causes to restore organized electrical activity.

Incorrect. Oxygen saturation should be maintained at 92-96% to prevent hypoxia and avoid the harmful effects of hyperoxia.

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

Incorrect. Stabilizes the myocardial membrane and prevents arrhythmias.

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

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

Incorrect. Oxygenation and ventilation should be closely monitored to prevent hypoxia and hyperoxia.

Incorrect. Epinephrine 1 mg IV/IO is administered every 3-5 minutes during cardiac arrest to improve coronary and cerebral perfusion.

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

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

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

Incorrect. CPR is the primary intervention for PEA, followed by epinephrine and identification of reversible causes.

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

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J, restoring organized electrical activity.

Incorrect. Rhythm checks should be performed every 2 minutes during CPR, coinciding with compressor role switches.

Incorrect. CPR should be resumed immediately after defibrillation to maintain perfusion and increase the likelihood of ROSC.

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

Incorrect. Chest compressions are performed to dislodge the obstruction and restore effective ventilation in an unresponsive infant.

Incorrect. With an advanced airway in place, uninterrupted compressions improve blood flow while ventilation is delivered separately.

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