I went to visit my mother in NH today. She told me that a CNA she did not know had punched her in her bottom early Monday morning. I asked if she had told anyone, she told the nurse the night before. That nurse was not in, so, I had my mother tell the on duty nurse. Then, that nurse brought in the supervisor and the director of nurses. The director of nurses is going to investigate, but, told me that since there did not appear to be bruising, the CNA must have just slipped while washing my mother. My mother is very sharp and insists that the CNA used excessive force! I do not have faith that the director of nursing is going to conduct an indepth investigation. I do not want the CNA near my mother! (or anyone else's) What to do next?
