Ok i need a refresher please. The only wounds you stage are pressure ulcers right? Venous/Arterial Ulcers are just measured, No stage,right? Also I know once a Stage IV always a Stage IV it can just become a healing stage IV or healed stage IV. But what about a Stage III? Still always a stage III because there was full thickness loss? Any advice, refreshers, answers would be greatly appreciated. :) Thanks
