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

Incorrect. Naloxone blocks opioid receptors and is administered to reverse opioid overdose and restore adequate respiration.

Incorrect. Prompt defibrillation within 30 seconds of witnessed VF arrest improves the chance of restoring a perfusing rhythm.

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

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

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

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

Incorrect. The jaw-thrust avoids neck movement, making it the preferred airway technique for patients with suspected cervical spine injuries.

Incorrect. Asystole is not a shockable rhythm; it is treated with high-quality CPR and epinephrine.

Incorrect. Atropine at 0.5 mg IV is the first-line treatment for symptomatic bradycardia caused by vagal stimulation.

Incorrect. Amiodarone is used after defibrillation and epinephrine for refractory VF to stabilize the myocardium.

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

Incorrect. Lidocaine is an alternative antiarrhythmic for refractory VF, dosed at 1 mg/kg IV/IO.

Incorrect. A left lateral tilt prevents aortocaval compression, improving venous return and cardiac output during resuscitation.

Incorrect. Rhythm checks are performed every 2 minutes to evaluate for shockable rhythms and assess the need for defibrillation.

Incorrect. Delivering 10 breaths per minute ensures adequate oxygenation without causing hyperventilation.

Incorrect. Synchronized cardioversion with 120-200 J is used to restore normal rhythm in unstable atrial fibrillation.

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

Incorrect. Maintaining a compression fraction of greater than 80% ensures the majority of resuscitation time is spent on compressions.

Incorrect. Adenosine is administered as a 0.1 mg/kg rapid IV push for pediatric SVT, followed by a saline flush.

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

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

Incorrect. Continuous chest compressions are performed while ventilations are delivered every 6 seconds when an advanced airway is in place.

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

Incorrect. Synchronized cardioversion with 50-100 J is effective for narrow, regular tachycardias that are unstable.

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

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

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

Incorrect. A PETCO2 reading above 10 mmHg indicates that chest compressions are generating sufficient circulation during CPR.

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

Incorrect. Adenosine is the first-line drug for treating narrow-complex SVT by slowing conduction through the AV node.

Incorrect. Hypoxia is one of the most common reversible causes of PEA and is addressed with high-quality oxygenation during resuscitation.

Incorrect. Pediatric defibrillation starts at 2 J/kg for the initial shock, increasing as needed based on the patient's response.
