What is the best way to talk to my mom about moving to a skilled nursing facility?

My mother is very willful and has insisted that she remain at home with a 24/7 caregiver. Her past caregiver recently took her to the ER with a stage 3 bedsore and was reported to Adult Protective Services. There is now an ongoing investigation. My mother is currently in a skilled nursing facility and wants to return home and is being quite difficult there. I live 3000 miles away and am traveling out to meet with her to try to discuss her future. Can you provide any suggestions for promoting a non-confrontational discussion about what she may and may not be able to do?
