First review her documents and finances. Florida is looser with their regulatory burden, so the issue will be that she will be safe while the cost not being as excessive as other locations. She might only need assistive living and not full nursing care for now.
If she hasn't named you or a sibling to have power of attorney get that setup, get one that covers everything and then get two real short ones one to cover medical records and one to handle checking any financial accounts and to be able to speak to her creditors. Have two originals for each, one stored in a waterproof and fire resistant small lockbox and the other in something that will keep them dry in a downpour. make a set of copies of the travel ones, some places will take your copy others will want to scan the original.
The documents and totalling resources, assets and income can be done anywhere, the part about typical local costs and Medicaid for eldercare is very state specific.
Get her a medicaid workup. And once this is behind you, get you and your spouse worked up, it is best to get that all setup 5 or even more years ahead, as you can shield assets from being used up needlessly. The middle class are the ones who really get fleeced during this stage.
With rehab encourage her to make small but slow and steady progress with rehab. upto 100 days per incident per year is covered under medicare but the gotcha is they have to be making 'progress' towards reasonable (set by standards of care) progress. The inpatient rehab pros can guide her on how to do the progress over that set of time. The key is she tries and that she makes incremental progress. My mom was an athlete in her college years, so she overshot a couple of times and got discharged a little earlier than ideal, try to avoid that.
Get cracking, you won't have much time to find her a space, some good places might have waiting lists. Shop around, ask around, ask her where anyone she knows went and any feedback she heard. If she or you are part of an organized religion seek out a local church or temple.
