Incorrect. Switching compressors every 2 minutes reduces rescuer fatigue, ensuring high-quality chest compressions are maintained.

Incorrect. High-quality CPR should be resumed immediately after a shock to maintain perfusion and increase the likelihood of ROSC.

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

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

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

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

Incorrect. Synchronized cardioversion at 100 J is effective for restoring a stable rhythm in unstable ventricular tachycardia.

Incorrect. A 15:2 ratio ensures efficient oxygenation and circulation in pediatric patients during two-rescuer CPR.

Incorrect. ROSC stands for "Return of Spontaneous Circulation," indicating the resumption of a perfusing rhythm.

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

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

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

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

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

Incorrect. With an advanced airway in place, compressions continue uninterrupted while breaths are delivered at 6-8 breaths per minute.

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

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

Incorrect. Avoid delays to minimize interruptions in chest compressions and maintain perfusion.

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

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

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

Incorrect. Providing 6-8 breaths per minute ensures adequate oxygenation and ventilation without interfering with chest compressions.

Incorrect. PETCO2 monitoring helps assess the effectiveness of both ventilation and chest compressions in real-time during CPR.

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

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

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

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation without risking incomplete recoil or excessive fatigue.

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

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

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

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

Incorrect. High-quality CPR is the primary intervention for PEA, followed by epinephrine administration and addressing reversible causes.

Incorrect. Magnesium sulfate is administered to stabilize the myocardium and terminate torsades de pointes.

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

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