This is the first of three articles that will explain what a colonoscopy is, and what the recommendations are in getting one. The following two articles will discuss the different types of common colon issues along with some unusual ones, and then the different types of preps and the reasoning behind each one. The purpose of these articles is to reinforce the necessity of doing a colonoscopy in prevention of cancer and to remind nurses of the importance of their role in educating patients about compliance with the testing and taking their preps properly.
