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

Incorrect. Placing hands on the lower half of the sternum ensures effective chest compressions without damaging other structures.

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

Incorrect. Atropine blocks vagal stimulation, increasing heart rate in cases of symptomatic bradycardia.

Incorrect. Two minutes of CPR (about 5 cycles of 30 compressions and 2 breaths) should be performed before reassessing the rhythm.

Incorrect. Epinephrine is the first-line drug for VF, with amiodarone as the preferred antiarrhythmic for refractory cases.

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

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

Incorrect. Early defibrillation within 30 seconds of a witnessed VF arrest increases survival rates significantly.

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

Incorrect. Epinephrine is given to improve perfusion pressure and increase the chance of ROSC in persistent VF.

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

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

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

Incorrect. The compression fraction should be greater than 80% to maximize perfusion during CPR.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be treated with warming measures.

Incorrect. High-quality CPR is the primary treatment for asystole, along with epinephrine and addressing reversible causes.

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