The patient is attached to a cardiac monitor. A rhythm check reveals multifocal premature ventricular contractions at 81/min. What are your initial actions?
The patient complains that their chest pain is worsening and that it is becoming increasingly difficult for them to inhale. Moments later, the patient loses consciousness, and a rhythm check reveals a conversion from multifocal premature ventricular contractions to ventricular fibrillation. A single unsynchronized shock of 120 J is delivered. What are your next actions?
Five cycles of CPR are performed. Following five cycles of CPR, a rhythm check reveals unchanged ventricular fibrillation. A single unsynchronized shock of 200 J is delivered, and CPR is resumed. During the first cycle of CPR, what drug should you administer?
