Looking for in home nurse visits twice a week. Where can I find help?

My father in law is confined to a hospital bed and we need to find nursing services which will come a couple times a week to address any medical issues he may have. He has the beginnings of bedsores now. He lives in Tucson Arizona and we live in Seattle and I'm trying to take care of him the best we can long-distance. He is a very angry man who mentally is beginning to slip but is still very bright. Unfortunately he is also confined to a body that is totally useless now.
