And to ease your mind a little, the visiting nurse answers to someone. I'm sure she is reporting the situation to someone. In order to have a visiting nurse, your neighbors would have had to have been assessed at some point and their situation documented.
You can call APS (Adult Protective Services) to see if they'll intervene and find a rehab facility for the wife to go while she's recovering from a broken arm, or perhaps advise what other arrangements can be made.
It does sound as if these people should not be living alone, especially in a second story dwelling.
Your local county may also have a health department that can become involved. I think at this point it probably will take governmental intervention, unless you can speak to their doctors pursuant to a HIPAA authorization.
