I have personal experiece with not only being a resident in a nursing home, but also worked in one. A twin size is a good size, but I would use a pattern/fabric that you didn't put a lot of work into. All items have to have their name on it, but it's amazing how much stuff of mine "got lost" in the laundry. If her family does her laundry, that is optimal. Make her that quilt...she will love it!!..Make her a fabulous one when she gets better. It would be her celebration quilt. As for batting, I would use a layer of flannel.
