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

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

Incorrect. Synchronized cardioversion restores organized cardiac activity in unstable atrial flutter.

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. Continuous chest compressions are performed while ventilations are delivered every 6 seconds when an advanced airway is in place.

Incorrect. A sudden increase in PETCO2 is a reliable indicator of ROSC, reflecting improved circulation and gas exchange.

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

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

Incorrect. PETCO2 monitoring provides continuous feedback on the quality of chest compressions and the effectiveness of resuscitation.

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

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

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

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

Incorrect. Compressions at 1/3 the depth of the chest ensure adequate perfusion while minimizing injury to internal organs.

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

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

Incorrect. Shouting for help ensures additional resources and a defibrillator are quickly available.

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

Incorrect. A 15:2 ratio is used during pediatric CPR with two rescuers to optimize ventilation and circulation.

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

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

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

Incorrect. Hypokalemia can cause cardiac arrhythmias and is included in the "H's" of reversible causes of cardiac arrest.

Incorrect. Synchronized cardioversion at 100 J is effective for restoring a stable rhythm in unstable ventricular tachycardia.
