Incorrect. Ventilation with an advanced airway should be provided at a rate of 1 breath every 6 seconds, or 10 breaths per minute.

Incorrect. Maintaining oxygen saturation at 92-96% prevents hypoxia and avoids complications associated with hyperoxia.

Incorrect. With an advanced airway in place, uninterrupted compressions improve blood flow while ventilation is delivered separately.

Incorrect. Maximum energy for monophasic defibrillators; for biphasic, follow manufacturer recommendations.

Incorrect. Atropine is given at 0.5 mg IV every 3-5 minutes for unstable bradycardia caused by vagal stimulation or primary AV block.

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

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

Incorrect. A compression fraction >80% ensures that the majority of CPR time is spent delivering chest compressions to improve outcomes.

Incorrect. TTM is used to reduce neurological injury post-ROSC by maintaining a core temperature of 32-36°C.

Incorrect. Post-ROSC care focuses on stabilizing ventilation and oxygenation to prevent hypoxia or hyperoxia.

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

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

Incorrect. Chest compressions should be paused for less than 10 seconds to minimize interruptions during CPR when delivering a shock.

Incorrect. Ventilations should be provided at a controlled rate of 6-8 breaths per minute to prevent hyperventilation.

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