I am a CNA. I have been a CNA for a few years now and have just started working at this Skilled Nursing facility. A few days ago we recieved a patient who had knee surgery and happens to be the grandmother of one of the people who works in the kitchen. They have already created many complaints over the CNAs , nurses and staff for everything. Today I walked by an area that I wasn't working in to help answer lights. A bathroom light was on , so I went in to help out. This room has three beds and three residents in it. The patient who had knee surgery was near the front door , and her roommate was in the restroom on a shower chair who uses a stand-up lift to get up. The patient who had knee surgery had one out of many of her grand-daughters there in the room and I asked her grand daughter politely if she could step out just for two minutes so I can bring out this patient and use the lift. (For privacy.) The grand-daughter went outside and I figured she heard me so I said thank you and closed the door. I bring out the lady from the restroom who has no pants on, and the granddaughter opened the door without knocking and walked inside and stood there. My patient , who could be seen from anyone who walked down the hallway, covered her private area and said "they will see me." I turned around and asked for her to please step out just for a second for privacy, and she yelled at me saying , "My grandma lives in here. I can be where I want." I reported this to my supervisor and she said she would speak with the family. One hour later as I am working in my area down the hallway, the granddaughter stood outside and stared at me from far away as I walked around. As I walked down the hallway closer to her and passed her, she continued to give me a look like I would expect in a bad neighborhood in the streets (the only way I can describe it) and would not take her eyes off of me. She did not stop watching me this way for 15 minutes. She glared at me as I walked around, as I sat down, when I went to say hi to residents. I was very near her and was speaking to people and It got to the point where I could not take it anymore. I finally just looked back , smiled and said hello. She did not respond and continued to give me a look, looking me up and down like she was going to hurt me. I have never felt so threatened by a family member and I do not know what to do or even report what happened because I don't know if it is considered harassment? Has anyone experienced this?
