has great advice for you deewee
For a female, you could apply scented hand cream up past her elbows and then paint her fingernails. Look and see if there are any cosmetics in her br. Ask her, "would you like a little face powder, a little lipstick, blush (older women may call it "rouge") make her up! Ask her about her life when she was you age, what she did for fun, what she wore for clothes, how she wore her hair etc...
Find a picture album and ask her about the persons in the photos, read her her favorite bible passages, look up recipes in a cookbook, or read the the newspaper. If theres a sun porch and she is ambulatory, get her up and change the scenery. "Mrs. Jones its beautiful outside today, lets go out on the porch"...make sure she has a wrap or a blanket to keep warm... read to her out there....or "Mrs. Jones, come keep me company while I sweep the porch, tidy the living room"...or whatever task needs to be done. She can sit there and watch you while you work...Great conversation starter talking about home decorating.
I seem to get a lot of great l interactions with clients (Male and female) reading the newspaper, the Bible, whatever history type books (Time /Life type books, readers digest, history from WWII on...Ask family members for large print books or to bring a bunch of flowers you can arrange with her and put @ her bedside.
Heck, I've even read seed catalogs and mail order catalogs to one client and had a great afternoon talking about gardening!
As for your first case, the daughter sounds like an inexperienced twit. Sometimes one must tactfully "prepare a room" as I once had to call it and ask where/which chair to use. "I dont think it's professional to have me sitting on your fathers bed while we do cognitive activities" -She couldn't find a chair fast enough...Our cognitive activity? Reading the paper and drinking coffee.
Enjoy the fun cases and grit your teeth with the not so good...
