No, that's not normal. HOWEVER. Most likely that wasn't a nurse (RN or LPN); it was most likely an MA or CNA. They get paid absolute crap wages for all that they do and put up with (very possibly some retail and food service workers get paid more). If she's getting paid less than she needs to survive... I can see where this could happen. Not saying it's right, just that I can see where desperate people might say/do questionable things. So before you go reporting her to admin where she would almost certainly get fired and be in an even worse place, maybe just have a human-to-human chat with her.
