A patient is undergoing preoperative teaching before cardiac surgery. The nurse explains that a temporary pacemaker will be placed later that day, and it will be removed after the surgery.

While teaching a CPR class, a student in the class asks what the difference is between cardioversion and defibrillation. What would be the nurse's best response? "Cardioversion is done on a beating heart; defibrillation is not." "The difference is the timing of the delivery of the electric current." "Defibrillation is synchronized with the electrical activity of the heart; cardioversion is not." "Cardioversion is always attempted before defibrillation because it is not as dangerous."

"The difference is the timing of the delivery of the electric current."

The client asks the nurse to explain what is meant by a ventricular bigeminy cardiac rhythm. What is the best response by the nurse? "It is when the heart conduction is primarily from the atrioventricular node." "The rhythm has a normal beat, then a premature beat pattern." "The rhythm is regular but fast."

"The two look very much alike; it is difficult to tell the difference." "The QRS complex in ventricular fibrillation is always narrow, while in ventricular tachycardia the QRS is of normal width." "The P-R interval will be prolonged in ventricular fibrillation, while in ventricular tachycardia the P-R interval is normal."
