I am a nursing supervisor during the night shift. I was asked by an LPN to assess a patient. This patient had not yet been assessed by her. She was simply getting report from off going nurse. Without giving too many details, her charting had many false entries regarding my involvement and my statements. I also found out that she was charting about this for over 3 hours off the clock. I do have witnesses for all events. Historically I have had issues with this nurse before with insubordination. Any advice?
