Incorrect. Calcium gluconate stabilizes the cardiac membrane and reduces the risk of life-threatening arrhythmias caused by hyperkalemia.

Incorrect. Synchronized cardioversion is used to terminate unstable SVT by restoring normal electrical activity in the heart.

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

Incorrect. Delivering 6-8 breaths per minute ensures adequate oxygenation without hyperventilation during CPR with an advanced airway.

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation without risking incomplete recoil or excessive fatigue.

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

Incorrect. Maintaining a compression fraction of greater than 80% ensures the majority of resuscitation time is spent on compressions.

Incorrect. Asystole is not a shockable rhythm; it is treated with high-quality CPR and epinephrine.

Incorrect. Ventricular fibrillation presents as a disorganized rhythm that requires immediate defibrillation.

Incorrect. Compressing the chest 2-2.4 inches ensures adequate blood flow while minimizing injury risks.

Incorrect. Amiodarone 300 mg IV/IO is administered after defibrillation and epinephrine to treat refractory VF or pulseless VT.

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

Incorrect. Pediatric defibrillation begins at 2 J/kg and increases to 4 J/kg for subsequent shocks if needed.

Incorrect. A supine position ensures proper electrode placement and effective delivery of defibrillation shocks.

Incorrect. Ventilations are delivered at a rate of 6-8 breaths per minute to prevent hyperventilation.

Incorrect. TTM is used to reduce neurological injury post-ROSC by maintaining a core temperature of 32-36°C.

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

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

Incorrect. The correct compression-to-ventilation ratio for adult CPR without an advanced airway is 30:2.

Incorrect. The correct initial dose of amiodarone for pulseless VT is 300 mg IV/IO, followed by 150 mg for a second dose if needed.

Incorrect. The jaw-thrust avoids neck movement, making it the preferred airway technique for patients with suspected cervical spine injuries.

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

Incorrect. PEA is not a shockable rhythm; it is treated with CPR and addressing reversible causes such as hypoxia or hypovolemia.

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