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

Incorrect. Amiodarone stabilizes the myocardium and is given as a bolus for refractory VF or pulseless VT.

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

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

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

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

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

Incorrect. Calcium gluconate stabilizes the cardiac membrane and reduces the risk of life-threatening arrhythmias caused by hyperkalemia.

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

Incorrect. The jaw thrust maneuver opens the airway without manipulating the cervical spine, protecting against spinal cord injury.

Incorrect. Administered every 3-5 minutes to restore circulation by increasing coronary and cerebral perfusion pressure.

Incorrect. Providing 6-8 breaths per minute prevents hyperventilation and maintains adequate oxygenation during CPR with an advanced airway.

Incorrect. Adult defibrillation with a biphasic defibrillator typically starts at 120-200 J, not 360 J, depending on the manufacturer's guidelines.

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

Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.

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

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

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

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

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

Incorrect. Synchronized cardioversion is indicated for unstable atrial fibrillation to restore sinus rhythm and prevent hemodynamic collapse.

Incorrect. Administered via rapid IV push, followed by a saline flush to terminate reentrant arrhythmias.

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

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

Incorrect. The two-thumb encircling technique provides high-quality compressions for infants during CPR.

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

Incorrect. Adenosine is administered as a rapid IV push at an initial dose of 6 mg to terminate stable SVT.
