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

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

Incorrect. Atropine should not exceed a total dose of 3 mg when treating symptomatic bradycardia in adults.

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

Incorrect. The two-thumb encircling technique provides high-quality compressions for infants during CPR.

Incorrect. Immediate CPR is required as asystole is a non-shockable rhythm.

Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.

Incorrect. A compression fraction >80% is required to maximize perfusion and improve survival rates during high-quality CPR.

Incorrect. Rhythm checks should be performed every 2 minutes, coinciding with rescuer role switches, to evaluate for shockable rhythms.

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

Incorrect. Delivers an electrical shock to depolarize the heart and restore a normal rhythm.

Incorrect. Administered via rapid IV push, followed by a saline flush to terminate reentrant arrhythmias.

Incorrect. Ventilation with an advanced airway should be provided at a rate of 1 breath every 6 seconds, or 10 breaths per minute.

Incorrect. Epinephrine is dosed at 0.01 mg/kg IV/IO during pediatric cardiac arrest to improve coronary and cerebral perfusion.

Incorrect. If VF persists after defibrillation and epinephrine, amiodarone is administered to stabilize the rhythm.

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

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

Incorrect. Needle decompression relieves pressure caused by tension pneumothorax, improving ventilation and circulation.

Incorrect. A 15:2 ratio is used during pediatric CPR with two rescuers to optimize ventilation and circulation.

Incorrect. Synchronized cardioversion is the treatment of choice for unstable ventricular tachycardia with a pulse.

Incorrect. A 30:2 ratio ensures sufficient oxygenation and circulation in adults during CPR without an advanced airway.

Incorrect. Activating EMS ensures help is on the way while you assess and initiate resuscitation.

Incorrect. Dopamine is used to improve heart rate and contractility in bradycardia unresponsive to atropine.

Incorrect. For adult CPR, the ratio ensures adequate perfusion and oxygenation when no advanced airway is in place.

Incorrect. The maximum dose of atropine for bradycardia is 3 mg, with doses given at 0.5 mg intervals every 3-5 minutes.

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. Epinephrine is the first-line drug for VF, with amiodarone as the preferred antiarrhythmic for refractory cases.

Incorrect. A single rescuer performs 30 compressions followed by 2 breaths to maximize perfusion and oxygenation in pediatric CPR.

Incorrect. PETCO2 monitoring ensures effective ventilation and provides feedback on the quality of chest compressions during CPR.

Incorrect. Provides external electrical stimuli to maintain adequate heart rate when atropine fails.

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

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

Incorrect. Rescuers should switch every 2 minutes to prevent fatigue and ensure high-quality compressions are maintained.

Incorrect. Epinephrine is given to improve perfusion pressure and increase the chance of ROSC in persistent VF.

Incorrect. Maintaining oxygen saturation at 92-96% prevents hypoxia and avoids complications associated with hyperoxia.

Incorrect. Maintaining oxygen saturation within this range ensures adequate oxygenation without the risk of hyperoxia.

Incorrect. Two rescuers are needed to maintain high-quality CPR with an advanced airway: one for compressions and one for ventilation.

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.
