I heard from Chris last night and her father is very slowly improving, they are raising his sodium and he seems to be tolerating the treatment. Chris is spending time at the hospital and with her mother and she gets a rare break to run home and get her mail. She does not have internet access at her parent's house so she contacted me when she was home briefly.
She said the grandchildren, including her daughter, have been very supportive and she is very grateful. A nephew is helping to get her from place to place when necessary.
She is hoping that they can arrange home care for her father when he is eventually released from the hospital. She is very grateful for the prayers and sends her love to all.
