I'm so sorry to hear about your mother's situation. It must be very hard for her and for you!
One avenue to pursue would be Adult Protective Services. If your mother has lots of evidence (driver's license, receiving Social Security checks, bank account etc.) of being a resident of Wisconsin, you could make the argument that your mother's home is in Texas.
A power of attorney executed in one state should be valid in another state.

There likely is little or nothing you can do unless you retain counsel. With counsel you may be able to use the health care POA or you might need to apply for guardianship. The issues are very complex and technical and may involve interstate choice of law and jurisdiction. Consult a highly experienced elder law attorney ASAP.

It sounds like your only recourse is to petition the court for guardianship/conservatorship of your mother. What your sisters are doing is called "granny nappy" and is common enough to be addressed by statute in many states. I do not practice in Texas, but it is my understanding that the Uniform Adult Guardianship and Protective Proceedings Jurisdiction Act was recently or is being adopted by Texas. That should help in establishing that Wisconsin is the appropriate state for the guardianship, but if your mother is in Texas, that is where I would start out by visiting with an attorney from there.
Let me add a few things to the good answers you received. I agree this sounds like a "granny nabbing." Important thing, your mother must be forceful and demand to be sent home. If not, she can call the police or APS and report, herself, that she is being held without her consent.
For you to assert those position on her behalf, you will need to be a guardian. Unfortunately, what your sisters are doing is forcing you to begin guardianship here which will be inconvenient for you. The medical power of attorney does not give you the right to determine where your Mom lives; thus, the police can't rely on it and force your sisters to let your Mom depart with you.
