RN refusing MA assignment

TuTonka-Yes, my first post, and I started the thread. I just wanted some advice from some other nurses, since I don't get alot of contact with other RN's since I work in private practice and have for many years. I wasn't sure if my expectations were out of line and if current practice had changed or was I reasonable to expect some help from my team mate. If I did wrong here, I sincerely apologize to ya'll!!!
