Just a quick update. A few days after my last post she developed pneumonia and a failing heart and had to be rushed to the hospital. We signed DNR orders and were ready for the end but, almost miraculously, she pulled through with the help of a competent hospital staff, oxygen therapy, and IV antibiotics.
She's back in the nursing home now and, other than her AZ, is looking pretty good. Her doctor put her on Aricept, and she is much calmer now. She recognizes family even though she can't say many words. The home lost her glasses, so that was a mini-issue looking for an optician with a kind heart who made her a set even though it was an older prescription and she wasn't there to be fitted. All in all, the NH was the best decision for her we've evern made. It allows us to rest knowing she's in good hands, and we get to visit her whenever we want. Thanks again for your support on this board.
