In Explaining to a Patient Who Is Being Dismissed from the Hospital

In explaining to a patient who is being dismissed from the hospital that he has a clean-contaminated wound, the nurse states:

A) "Although the wound is an incision, it was grossly contaminated during surgery, so it is important to notify your physician if the drainage increases."
B) "Your incision seems to be developing a purulent drainage. Make sure that you notify your doctor if you notice that the drainage develops a foul smell."
C) "Your drainage cultured a high number of microorganisms, but since we've seen no evidence of infection and you are taking an antibiotic, you probably don't need to worry about it."
D) "Surgical wounds are exposed to normal flora that resides on the skin. It is important to observe it for signs of infection, such as drainage that turns yellow or green."
