tying to get either power of attorney, temporary guardianship

While your mother may grant a power of attorney, if her stroke has rendered her unable to manage her finances, a guardianship of the estate (conservatorship) is in order.  If her stroke has rendered her unable to make or communicate medical decisions, she may be able to make and communicate a decision as to who should make and communicate them for her, granting a medical power of attorney.  If not, a guardianship of the person is in order.  You may want to discuss this with an elder lawyer, with all the implications it has for applying for public benefits such as Medicaid.  You can find one near you on the website of the National Academy of Elder Law Attorneys (www.naela.org)
