Incorrect. Needle decompression relieves pressure caused by tension pneumothorax, improving ventilation and circulation.

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

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

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

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

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

Incorrect. Atropine is the first-line drug for symptomatic bradycardia, increasing heart rate by blocking vagal stimulation.

Incorrect. These shockable rhythms require immediate defibrillation to restore a perfusing rhythm.

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

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

Incorrect. Rhythm checks are performed every 2 minutes to evaluate for shockable rhythms and assess the effectiveness of interventions.

Incorrect. PEA is not a shockable rhythm; it is managed with high-quality CPR and addressing the underlying reversible causes.

Incorrect. PEA is treated with epinephrine and high-quality CPR to address underlying reversible causes.

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

Incorrect. Synchronized cardioversion is the treatment of choice for unstable ventricular tachycardia with a pulse.

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

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

Incorrect. Pulse checks should be limited to 10 seconds to minimize interruptions in chest compressions.

Incorrect. Pediatric defibrillation starts at 2 J/kg, increasing to 4 J/kg for subsequent shocks if needed.

Incorrect. Epinephrine is given as a continuous infusion to maintain adequate heart rate and perfusion when atropine is ineffective.
