The most common cause of death resulting from myocardial infarction is:

A) end-organ failure. B) inadequate tissue perfusion. C) heart failure. D) dysrhythmia.

You have just performed synchronized cardioversion on a patient with unstable ventricular tachycardia. Upon reassessment, you note that the patient is unresponsive, apneic, and pulseless. You should:

A) desynchronize the defibrillator, defibrillate one time, and check for a pulse. B) ensure that the synchronizer is off, defibrillate, and immediately begin CPR. C) increase the energy setting on the defibrillator and repeat the cardioversion. D) perform five cycles of CPR, reassess the cardiac rhythm, and defibrillate if needed.
