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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

Incorrect. Pulse checks should be limited to 5-10 seconds to minimize interruptions in chest compressions.

Incorrect. Ventilations should be provided at a controlled rate of 6-8 breaths per minute to prevent hyperventilation.

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

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

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

Incorrect. Adenosine is used for narrow-complex SVT, not wide-complex tachycardia, which is typically treated with amiodarone.

Incorrect. The jaw thrust maneuver opens the airway without moving the cervical spine, reducing the risk of spinal injury.

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

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

Incorrect. Pediatric defibrillation starts at 2 J/kg, increasing to 4 J/kg for subsequent shocks if needed.

Incorrect. IV access is preferred for rapid administration; IO is the alternative if IV access is unavailable.

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

Incorrect. Adenosine is administered at 0.1 mg/kg as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

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

Incorrect. Magnesium sulfate is administered to stabilize the myocardium and treat torsades de pointes effectively.

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

Incorrect. Two minutes of CPR (about 5 cycles of 30 compressions and 2 breaths) should be performed before reassessing the rhythm.

Incorrect. For unstable narrow, irregular tachycardias, synchronized cardioversion at 120-200 J is recommended.
