Incorrect. Synchronized cardioversion restores organized cardiac activity in unstable VT with a pulse, preventing progression to VF.

Incorrect. Positioning the patient with a slight left tilt prevents aortocaval compression and improves venous return during CPR.

Incorrect. Adenosine is administered as a 6 mg rapid IV push, followed by a saline flush, to terminate reentrant arrhythmias.

Incorrect. Epinephrine is administered every 3-5 minutes during pediatric cardiac arrest to enhance coronary and cerebral perfusion.

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

Incorrect. IO access provides a reliable alternative for rapid drug delivery during resuscitation when IV access cannot be obtained.

Incorrect. Pediatric defibrillation begins at 2 J/kg for the first shock and increases as necessary for subsequent shocks.

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

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

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

Incorrect. Prevents progression to cardiac arrest by restoring a normal rhythm.

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

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

Incorrect. PEA is not treated with adenosine; it is managed with CPR, epinephrine, and identifying and treating reversible causes.
