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

Incorrect. Oxygen saturation should be maintained at 92-96% to prevent hypoxia and avoid the harmful effects of hyperoxia.

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

Incorrect. A sudden increase in PETCO2 is a reliable indicator of ROSC, reflecting improved circulation and gas exchange.

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

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and epinephrine to optimize perfusion.

Incorrect. Waveform capnography ensures proper ET tube placement by monitoring exhaled CO? levels.

Incorrect. Rescuers should switch roles every 2 minutes to maintain high-quality chest compressions and prevent fatigue.

Incorrect. Adenosine is administered at 0.1 mg/kg as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

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

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating reentrant arrhythmias causing narrow-complex tachycardia.

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

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

Incorrect. Pulseless VT is treated with defibrillation, while synchronized cardioversion is reserved for tachyarrhythmias with a pulse.

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

Incorrect. Early defibrillation is critical for survival, especially in shockable rhythms like VF/VT.

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

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

Incorrect. Waveform capnography ensures proper ET tube placement by continuously monitoring exhaled CO? levels.

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

Incorrect. Ventilations are delivered every 6-8 seconds to provide oxygenation without interrupting chest compressions.

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

Incorrect. Atrial fibrillation is cardioverted starting at 120-200 J in synchronized mode to avoid delivering the shock during ventricular repolarization.

Incorrect. The correct compression rate for CPR is 100-120 compressions per minute to optimize perfusion and prevent fatigue.

Incorrect. Oxygen levels should be monitored and optimized to maintain saturation within the target range of 92-96%.

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

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

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

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

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

Incorrect. Naloxone reverses opioid-induced respiratory depression, restoring normal respiratory function.

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