My 84 year old father is on hospice and lives with me. I have done everything to modify my home to address his needs. He is very weak and on oxygen. Due to his weakness and previous falls, he has been told to ask for assistance to help with getting out of bed. He refuses and insists on doing it on his own. He refuses to have a portable commode in his room. What can I do? Stressed over worry he will fall again.
