? re: closed trials

I am new as a research RN. I am very unfamiliar with all the legalities of it but had been given a heads-up from a former colleague to be very careful about documentation etc. My question is, I literally just started at a hospital and within my first week was given 11 separate clinical trials...in addition, I was added as the contact nurse for trials already closed...even though I had nothing to do with them. This is very concerning to me and I'm wondering if anyone feels it's appropriate to say something. If it isn't actually a big deal, I don't want to make it an issue but I just feel I shouldn't have my name attached to anything I wasn't involved with...especially if that means I could be help accountable! Any suggestions/advice? Thank you...
