CCI Certified Perioperative Nurse (CNOR) Practice Exam

In wound classification, the level of bacterial contamination and whether a mucosal tract is entered determine the category. A clean wound is an uninfected operative wound in which no respiratory, alimentary, genital, or urinary tract is entered and there is no inflammation. Since the tract was not entered and there is no infection, this scenario fits clean. This category has the lowest risk of postoperative infection and often does not require extensive antibiotic prophylaxis beyond routine sterile technique.

Other possibilities would involve entering a tract under controlled conditions (clean-contaminated), a wound with a major contamination or a break in sterile technique (contaminated), or an already infected or nonviable tissue wound (dirty/infected).
