Incorrect. Delivering 1 breath every 5-6 seconds prevents hypoventilation or hyperventilation.

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

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

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

Incorrect. This rate ensures effective circulation without causing inadequate ventricular filling.

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J to treat VF or pulseless VT.

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

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

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

Incorrect. Lidocaine is an antiarrhythmic drug used as an alternative to amiodarone for VF or pulseless VT.

Incorrect. PETCO2 monitoring provides real-time feedback on ventilation and the effectiveness of chest compressions.

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

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

Incorrect. The most reliable method to confirm and monitor placement by measuring exhaled CO?.

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

Incorrect. Hypovolemia is a reversible cause of cardiac arrest and should be corrected with fluid resuscitation.

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

Incorrect. Pediatric defibrillation begins at 2 J/kg for the first shock and increases as necessary for subsequent shocks.

Incorrect. Oxygen saturation should be maintained at 92-96% to avoid hypoxia and reduce the risk of hyperoxia and oxidative stress.

Incorrect. Delivering 6-8 breaths per minute minimizes interruptions in chest compressions and prevents hyperventilation.

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

Incorrect. PETCO2 values greater than 10 mmHg during CPR indicate adequate chest compressions and blood circulation.

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

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

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

Incorrect. Switching every 2 minutes reduces rescuer fatigue and ensures high-quality chest compressions.

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

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

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

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

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

Incorrect. PEA is treated with CPR, epinephrine, and identifying reversible causes to restore organized electrical activity.

Incorrect. Placing hands on the lower half of the sternum ensures effective chest compressions without damaging other structures.

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

Incorrect. High-quality CPR should be resumed immediately after defibrillation to maintain perfusion and increase chances of ROSC.

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

Incorrect. Early defibrillation within 30 seconds of a witnessed VF arrest increases survival rates significantly.

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

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

Incorrect. Hypovolemia is a reversible cause of PEA and can be treated with rapid fluid resuscitation.

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

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