Incorrect. PEA is treated with epinephrine and high-quality CPR to address underlying reversible causes.

Incorrect. PETCO2 readings above 10 mmHg during CPR indicate adequate chest compressions and cardiac output.

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

Incorrect. Amiodarone stabilizes the myocardium and is given as a bolus for refractory VF or pulseless VT.

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

Incorrect. Early stabilization of blood pressure and oxygenation is critical to preventing further cardiac arrest after ROSC.

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

Incorrect. For biphasic defibrillators, 120-200 J is the recommended energy range for VF.

Incorrect. Epinephrine is repeated every 3-5 minutes during cardiac arrest to enhance perfusion pressure.

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

Incorrect. Waveform capnography provides real-time confirmation of ET tube placement and ensures proper ventilation.

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

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