If you can get your hands on it pick up a copy of "the Nurses Pocket Guide to Care Plans, Inteventions and rationals." It a paperback and not too expensive.
My first thought from your case scenario would be some kind of Alteration in Comfort Dx.
Followed by a Skin Integrity plan, Also a Nursing DX related to his psychological status would be good.
Hope this helps
