Incorrect. IM epinephrine is the first-line treatment for anaphylaxis, administered into the mid-thigh for rapid absorption.

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

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

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

Incorrect. The same compression rate as adults ensures adequate perfusion in pediatric patients during CPR.

Incorrect. Hypoxia is the most frequent reversible cause of PEA and should be addressed immediately with oxygenation and ventilation.

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

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

Incorrect. Amiodarone is the preferred antiarrhythmic for stabilizing wide-complex tachycardia in stable patients.

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

Incorrect. Atropine doses should not exceed 3 mg during bradycardia management to avoid adverse effects.

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

Incorrect. Adenosine is the first-line drug for treating narrow-complex SVT by slowing conduction through the AV node.

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

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

Incorrect. A PETCO2 reading above 10 mmHg indicates that chest compressions are generating sufficient circulation during CPR.

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

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

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

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

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

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

Incorrect. PETCO2 >10 mmHg during CPR indicates effective chest compressions generating sufficient circulation.

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

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

Incorrect. Amiodarone is used after defibrillation and epinephrine for refractory VF to stabilize the myocardium.

Incorrect. Pausing compressions for more than 10 seconds interrupts perfusion and reduces the chances of ROSC.

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

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

Incorrect. Maintaining oxygen saturation at 92-96% avoids hypoxia while preventing hyperoxia, which can cause further tissue damage.

Incorrect. Epinephrine at 0.01 mg/kg IV/IO is administered every 3-5 minutes to enhance coronary and cerebral perfusion in children.

Incorrect. PETCO2 readings above 10 mmHg during CPR indicate adequate chest compressions and cardiac output.

Incorrect. Optimal for maintaining adequate circulation without risking poor perfusion due to excessive speed.

Incorrect. Maintaining this range prevents hypoxia while minimizing the risks of hyperoxia and oxidative injury.

Incorrect. Indicates effective chest compressions and blood circulation during resuscitation.

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

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

Incorrect. Ventricular fibrillation (VF) is a shockable rhythm and requires immediate defibrillation to restore an organized rhythm.

Incorrect. Naloxone is used to reverse opioid overdose, restoring respiratory effort in patients with respiratory depression.

Incorrect. TTM helps reduce neurological injury by maintaining a core temperature of 32-36°C after the return of spontaneous circulation.

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

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

Incorrect. Rotating team roles every 2 minutes prevents fatigue, ensuring consistent delivery of high-quality chest compressions.

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

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation in pediatric patients.

Incorrect. Adenosine is used to terminate stable narrow-complex tachycardia by slowing AV node conduction.

Incorrect. Asystole is a non-shockable rhythm treated with high-quality CPR and epinephrine.

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

Incorrect. Magnesium sulfate is used to treat torsades de pointes but is not the first-line drug for VF, where epinephrine is prioritized.

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

Incorrect. Compressing 2-2.4 inches ensures effective perfusion during adult CPR while minimizing the risk of injury.

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

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

Incorrect. Immediate defibrillation is the most effective intervention for a witnessed cardiac arrest in VF.

Incorrect. Hypoxia is one of the most common reversible causes of PEA and is addressed with high-quality oxygenation during resuscitation.

Incorrect. Atropine at 0.5 mg IV is the first-line treatment for symptomatic bradycardia caused by vagal stimulation.

Incorrect. Chest compressions for infants should be about 1/3 the depth of the chest, approximately 1.5 inches (4 cm).

Incorrect. Assessing responsiveness is the first step in determining the need for CPR or other interventions in the BLS survey.

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

Incorrect. Dopamine is used when atropine is ineffective, improving heart rate and contractility by stimulating beta receptors.

Incorrect. Defibrillation is the priority for VF and should not be delayed for drug administration, as it is the definitive treatment.
