Hello, Mrs. Fox. I am so sorry about your mom. It is good that you are getting Power of Attorney, but also be sure to get a Medical Surrogacy. That is often in the forms for a Living Will. You need to find out what your mom's wishes are while she is still cognizant.
When is her next doctor appt.? Is she seeing a hepatologist? You need to find out exactly where she stands medically. Has she applied for SSI/SSD? If not, she should do so, or you can do the paperwork for her. She also needs to apply for Medicaid, if she is financially eligible. They could pay for a nursing home or perhaps assisted living, if that is necessary.
Read some of the older posts here and you will get an idea of what to expect and what you should be doing. If you mom's doctor does not think she has much time left, you can get Hospice involved.
I know we can be of great support to you, and hopefully be some help as for as information.
