A 57-year-old woman has palpitation, chest discomfort, and tachycardia. The monitor shows a
regular wide-QRS at a rate of 180/min. She becomes diaphoretic, and her blood pressure is 80/60
mm HG/ Which action do you take next? - Answer>>> Perform electrical cordioversion
After initiation of CPR and 1 shock for ventricular fibrillation, this rhythm is present on the next
rhythm check. A second shock is given, and chest compressions are resumed immediately. An
IV is in place, and no drugs have been given. Bag-mask ventilations are producing visible chest
rise. What is your next intervention? - Answer>>> Give epinephrine 1mg IV/IO
A patient's 12-lead ECG is transmitted by the paramedics and shows a STEMI. When the patient
arrives in the emergency department, the rhythm shown here is seen on the cardiac monitor. The
