That may work, or you may need something MORE than just a PoA. Is your sister disabled in such a way that she cannot understand what a power of attorney is and what she is doing by signing such a document? Is this purely a physical disability, or is there a mental issue?
If it is PURELY physical then it is pretty clear an adult can sign a power of attorney naming anyone they see fit to name to handle their affairs.
If your sister is under 18 or there are mental disability issues, then I would STRONGLY urge you to consult with a local lawyer to see what you need to do. If the impairment is slight, then a PoA may still be possible, but again, you need someone to assess her 'testamentary capacity' to determine this.
IN ANY EVENT, a PoA or other documents drafted by an attorney will be far more likely to do what you need them to do. Seek local legal help.

If she has full mental capacity and can understand what the power of attorney is, yes you can be her agent on a power of attorney. However, if she does not have mental capacity, you may require a court proceeding to secure the appropriate authority. I would caution you that if she does not have mental capacity, that it may be inappropriate to move her from the facility as Adult Protective Services may be involved, which could then get potentially get you into trouble. If you have any doubt, you should talk to an attorney before you do anything.
If your sister has legal capacity, she may appoint you as her agent under POA.
