The patient's wife asks the nurse if the angioplasty will remove all the buildup in the vessel walls so that the patient will be healthy again. What explanation should the nurse provide? a. "The operation will remove all of the plaque, and if your husband exercises and diets he will be free of cardiac problems." b. "The surgery will remove all the buildup, but it will reaccumulate and he will probably need this surgery again this time next year." c. "The best outcome will be if 20% to 50% of the diameter of the vessel can be restored. Your husband will need to diet and exercise carefully to avoid further cardiac risk." d.
