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

Incorrect. Thrombosis (pulmonary or coronary) is a reversible cause of cardiac arrest and should be addressed immediately.

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

Incorrect. High-quality CPR should be resumed immediately after defibrillation to maintain perfusion and increase chances of ROSC.

Incorrect. PETCO2 monitoring provides real-time feedback on chest compressions and the effectiveness of CPR.

Incorrect. PETCO2 values greater than 10 mmHg during CPR indicate adequate chest compressions and blood circulation.

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

Incorrect. Ventricular fibrillation (VF) is a shockable rhythm and requires immediate defibrillation to restore an organized rhythm.

Incorrect. Switching compressors every 2 minutes reduces rescuer fatigue, ensuring high-quality chest compressions are maintained.

Incorrect. Synchronized cardioversion with 120-200 J is used to restore normal rhythm in unstable atrial fibrillation.

Incorrect. Ventricular fibrillation is the most common cause of sudden cardiac arrest and requires immediate defibrillation.

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

Incorrect. Hypovolemia is a common reversible cause of PEA and should be addressed with rapid fluid resuscitation.

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

Incorrect. Rescuers should switch every 2 minutes to prevent fatigue and ensure high-quality compressions are maintained.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be treated with warming measures.

Incorrect. The correct compression rate for CPR is 100-120 compressions per minute to optimize perfusion and prevent fatigue.

Incorrect. These shockable rhythms require immediate defibrillation to restore a perfusing rhythm.

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

Incorrect. A compression fraction >80% ensures that the majority of CPR time is spent delivering chest compressions to improve outcomes.

Incorrect. Synchronized cardioversion is indicated for unstable atrial fibrillation to restore sinus rhythm and prevent hemodynamic collapse.

Incorrect. Adenosine is the first-line drug for stable SVT, while synchronized cardioversion is used for unstable SVT.

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

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

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

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

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

Incorrect. Interruptions in chest compressions should not exceed 10 seconds to maintain adequate perfusion to vital organs.

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

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

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

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

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

Incorrect. Amiodarone is used to stabilize wide-complex tachycardias in stable patients to prevent deterioration into cardiac arrest.

Incorrect. The 15:2 ratio improves oxygenation and circulation during high-quality infant CPR performed by two rescuers.

Incorrect. The compression-to-ventilation ratio for single-rescuer infant CPR is 30:2, ensuring sufficient oxygenation and circulation.
