Incorrect. Magnesium sulfate is the first-line treatment for torsades de pointes as it stabilizes the myocardium.

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

Incorrect. The initial dose of adenosine for stable SVT in adults is 6 mg IV, followed by 12 mg if needed for subsequent doses.

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

Incorrect. Atropine is given at a dose of 0.5 mg every 3-5 minutes during bradycardia, up to a maximum dose of 3 mg.

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

Incorrect. Amiodarone is preferred, but lidocaine is an alternative antiarrhythmic for refractory VF or pulseless VT.

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

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

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

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

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

Incorrect. TTM helps reduce neurological injury after ROSC by maintaining a target temperature between 32-36°C.

Incorrect. Atrial flutter presents as a sawtooth pattern on the ECG and requires rate control or cardioversion depending on stability.

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

Incorrect. The correct dose of epinephrine for pediatric cardiac arrest is 0.01 mg/kg IV/IO, not 1 mg/kg.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.

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

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

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

Incorrect. Post-ROSC care focuses on optimizing oxygenation, ventilation, and hemodynamic stability to prevent further organ damage.

Incorrect. Adequate oxygenation and ventilation are critical to preventing hypoxia or hyperoxia after ROSC.

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

Incorrect. The 15:2 ratio improves oxygenation and circulation during high-quality infant CPR performed by two rescuers.

Incorrect. ROSC signifies the resumption of spontaneous cardiac activity with effective circulation, improving patient survival.

Incorrect. Synchronized cardioversion is indicated for unstable atrial fibrillation to restore sinus rhythm and prevent hemodynamic collapse.

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

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

Incorrect. A PETCO2 level greater than 10 mmHg indicates that chest compressions are generating adequate blood flow.

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

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

Incorrect. Rapid defibrillation within 1 minute of witnessed VF increases the likelihood of survival and ROSC.

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

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

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

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