Since your fellow student was acting in role of CNA in the capacity of the hospital, then really (and you seem to know this now) you should have spoken to her supervisor if you wanted to address it. But here is the problem: all you have is heresay (plus some common sense telling you that she HAD to be the source of rumors), so you really would only be 'reporting' an opinion that this person said something (unless someone else is willing to stick out her neck in support). I just think that you made too much of it. Are you going to call everyone who ever says anything bad about you? Most of us would be on the phone 24 X 7...

Anyway...if no greater risk than insulin was your exposure, then I'd count my blessings that I didn't have a bloodborne risk as well and consider this a valuable lesson. Just thinking...is it possible that the real problem is that you are mostly just embarrassed and ticked off to have had a witness, who happened to be a not-so-nice blabbermouth as well ? I agree that she is an annoying little (big?) twit for talking about you, and it always irks me that all this gossip stuff is a part of nursing school, but I say live & learn and laugh as much as you can. Sometimes the more you make of it, the worse YOU look...that's one of the ironies of life. But an ever-present sense of humor and constant attitude of professionalism & kindess will ensure that you survive all the annoying little twits out there!
