I'm a BSN nursing student, and today I had a clinical rotation at the hospital. The CNA on the floor there was taking out IVs and Foley catheters. I don't work as a CNA, but I did take the class and I'm pretty sure that you're not allowed to do that (at least in my home state). If I see this, am I obligated to say something to someone about it? I feel like it's wrong but I didn't know what to do at the time. Is this a common happening and what should I do about it? Thanks so much!
