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

Incorrect. Oxygenation and ventilation should be optimized to avoid hypoxia or hyperoxia during post-cardiac arrest care.

Incorrect. PEA is treated with CPR and epinephrine, as defibrillation is ineffective for non-shockable rhythms.

Incorrect. A compression fraction greater than 80% ensures that most of the resuscitation time is spent performing chest compressions.

Incorrect. Pulseless VT is a shockable rhythm that requires immediate defibrillation to restore a perfusing rhythm.

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and must be corrected to restore spontaneous circulation.

Incorrect. Compressing the chest 2-2.4 inches ensures adequate blood flow while minimizing injury risks.

Incorrect. Positioning the patient with a slight left tilt prevents aortocaval compression and improves venous return during CPR.

Incorrect. Two rescuers are needed to maintain high-quality CPR with an advanced airway: one for compressions and one for ventilation.

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

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

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. Adenosine 6 mg is given as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

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

Incorrect. VF is a shockable rhythm, and defibrillation is the primary treatment to restore an organized rhythm.

Incorrect. A PETCO2 reading above 10 mmHg indicates adequate chest compressions and cardiac output during CPR.

Incorrect. Rescuers should switch every 2 minutes to prevent fatigue and ensure high-quality compressions are maintained.

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

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

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

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

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

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

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

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

Incorrect. Targeted temperature management improves neurological outcomes by preventing further brain injury.

Incorrect. Compressing one-third the depth of the chest ensures adequate perfusion while minimizing the risk of injury.

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

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

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

Incorrect. Ventricular fibrillation presents as a disorganized rhythm that requires immediate defibrillation.

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

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

Incorrect. PETCO2 monitoring provides continuous feedback on the quality of chest compressions and the effectiveness of resuscitation.

Incorrect. The correct initial dose of amiodarone for pulseless VT is 300 mg IV/IO, followed by 150 mg for a second dose if needed.

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

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

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

Incorrect. Defibrillation attempts should be separated by 2-minute CPR cycles to ensure effective perfusion and rhythm evaluation.

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

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

Incorrect. The maximum dose of atropine for bradycardia is 3 mg, with doses given at 0.5 mg intervals every 3-5 minutes.

Incorrect. Pediatric defibrillation starts at 2 J/kg and may increase to 4 J/kg for subsequent shocks if VF persists.

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

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

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

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

Incorrect. For adult CPR, the ratio ensures adequate perfusion and oxygenation when no advanced airway is in place.

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

Incorrect. Maintaining a compression fraction above 80% ensures adequate blood flow during resuscitation.

Incorrect. Compressing to a depth of 2-2.4 inches ensures adequate circulation without causing damage to internal organs.

Incorrect. Epinephrine is given first in VF during cardiac arrest, followed by amiodarone as an antiarrhythmic after defibrillation attempts.

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

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