How do I get power of attorney for my incapacitated mother?

Your mother can only grant you a Medical or Durable [Financial] Power of Attorney if she has legal capacity to do so.  She may have legal capacity to grant a Medical Power of Attorney, allowing you to be her voice with regard to medical care to the extent that this is not trumped by her decision to enter hospice care, but not the legal capacity to grant a Durable [Financial] Power of Attorney, allowing you to access her finances.  Elder lawyers do make "house calls."  You can locate one near you using the Find a Lawyer function on the website of the National Academy of Elder Law Attorneys (www.naela.org)
