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

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

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

Incorrect. A 30:2 ratio ensures adequate oxygenation and circulation when no advanced airway is present.

Incorrect. A compression fraction greater than 80% ensures that most of the resuscitation time is spent performing chest compressions.

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

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

Incorrect. Atropine is given at 0.5 mg IV every 3-5 minutes for unstable bradycardia caused by vagal stimulation or primary AV block.

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

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

Incorrect. CPR is the primary intervention for PEA, followed by epinephrine and identification of reversible causes.

Incorrect. Hypovolemia is a common reversible cause of PEA and should be addressed with rapid fluid resuscitation.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and administration of epinephrine.

Incorrect. Pulse checks during CPR should not exceed 10 seconds to minimize interruptions in chest compressions.

Incorrect. With an advanced airway, compressions continue uninterrupted while ventilation is provided at a rate of 10 breaths per minute.

Incorrect. Pulseless VT is treated with defibrillation, not atropine. Atropine is used for symptomatic bradycardia.

Incorrect. Magnesium sulfate stabilizes the cardiac membrane and is the drug of choice for treating torsades de pointes.

Incorrect. Pediatric defibrillation starts at 2 J/kg and may increase to 4 J/kg for subsequent shocks if VF persists.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and epinephrine to optimize perfusion.

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

Incorrect. Synchronized cardioversion with 50-100 J is effective for narrow, regular tachycardias that are unstable.

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

Incorrect. Amiodarone is administered as a 300 mg IV/IO bolus for refractory VF or pulseless VT.

Incorrect. Providing 6-8 breaths per minute prevents hyperventilation and maintains adequate oxygenation during CPR with an advanced airway.

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

Incorrect. Adenosine is administered as a 0.1 mg/kg rapid IV push for pediatric SVT, followed by a saline flush.

Incorrect. Naloxone reverses opioid-induced respiratory depression, restoring normal respiratory function.

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

Incorrect. Epinephrine is given at a dose of 1 mg IV/IO every 3-5 minutes during adult cardiac arrest to improve perfusion.

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

Incorrect. Adenosine is used to terminate reentrant arrhythmias in narrow-complex SVT by slowing conduction through the AV node.

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