I'm so glad she's doing much better!
As for being so far from the nurses station, I can tell you that is probably a good thing. They can get so noisy, with talking and banging and such. It'll be a lot quieter where she is and she'll sleep better.
You might tell Mamarider to get some twine or string and run it from one side of the wall to the other and she can hang the cards on it. If she starts it on the wall from BR's feet and brings it to the wall behind her head, she may be able to see the cards better. Just keep it above head level so no one runs into it.
Tape may not adhere to the wall very well. There are these glue dots out that work pretty well. One brand is called "Dots". They should come off the wall fairly well but probably not from the cards. They are sort of like that sticky stuff that is on the back of a credit card you might get in the mail that is stuck to the letter. You know what I mean? Anyway, you can try the tape and if it doesn't work you can try those. You can get them at a scrapbooking place or an arts and crafts place.
Don't forget the hand and foot lotion. Hospitals can be so dry.

When choosing between two evils, I always like to take the one I've never tried before.
