I have a senior nurse who has been an LPN for 4 years. She thinks she knows everything and is diagnosing co-workers who are crazy enough to ask her what their s/s mean. She also talks down about other nurses to new nurses and current nurses. She did it when she was training me and I learned she talked about me really bad to a new nurse hire. She yells and does not think anyone should say anything back to her. She also gossips with subordinate CNAs about other staff. I want to put a recorder on her med cart and record her and send to the nursing board. She is actually diagnosing patients and staff who tells her their s/s. These patients and staff ask other nurses, including myself, "I have ------ going on. What do you think that is?" I reply, "Look/Sounds like something you should get your doctor to look at". I make it a teaching moment and let them know that I am not a doctor and will not tell them they have a certain condition based on the info they give me. That is what doctors are for. They actually hold the nurse to whatever she says. Patients have stated, "The other nurse told me I have ---- and I need ----- medication. What do you think?". Should I tell the director?
