Have a resident who is basically noncomplaint in all aspects. Knows it all and self diagnoses. We'll skip the mental issues the staff is in agreement about. Never comes to the Dinning Room (DR) on time. Will come in after meal time with others in tow wanting a meal for herself and them. No matter how many times you inform her it's time to go to DR, she does her own thing, ie makes a telephone call immediately after you remind her. It is a problem for the dietary staff. Basically college and high school students. DON says remind her and if she's not in the DR go ask her if she wants a tray bought to her room. Well, it might sound like a little thing to do, but the CNA is in the DR feeding and the nurse is doing the med pass. So walk down to her room from the DR, then if she wants the food on a tray, go back to the DR get the meal and then back down to the room.When she didn't show up to the dinning room by 6pm had the CNA put her meal on a tray and took it to her room. She refused to have the meal in her room and wanted in the DR. Met her in the hallway and said that dinner is served at 5:30PM, it is now 6:10pm and they are done serving and going to start clean up. She just doesn't care.I have left several messages for social services about this. The dietary staff is fustrated. Where can the line be drawn without violating residents' rights. One of the rights' listed in the facilities residents' rights is to be served in the DR at the designated hours.Any suggestions?Thanks and Merry Christmas!
