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

Incorrect. Pausing compressions for more than 10 seconds interrupts perfusion and reduces the chances of ROSC.

Incorrect. The jaw thrust technique opens the airway while minimizing cervical spine movement, reducing the risk of further injury.

Incorrect. Post-ROSC care focuses on maintaining oxygenation and avoiding hypoxia or hyperoxia to protect organ function.

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

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

Incorrect. Synchronized cardioversion is used to terminate unstable SVT by restoring normal electrical activity in the heart.

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

Incorrect. Adequate oxygenation and ventilation are critical to preventing hypoxia or hyperoxia after ROSC.

Incorrect. Oxygenation and ventilation should be closely monitored to prevent hypoxia and hyperoxia.

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

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

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

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

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating narrow-complex SVT caused by reentrant circuits.

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

Incorrect. Epinephrine is administered to increase coronary and cerebral perfusion pressure during cardiac arrest.

Incorrect. Hypovolemia is a reversible cause of cardiac arrest that can be treated with fluid resuscitation to restore circulation.

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