Need advise please!!!!I'm a LPN working as a treatment nurse. My supervisor is an RN. One of our treatments is to apply a unna boot to a patients legs who has stasis ulcers and a good bit of edema. He also has a small ulcer on the side of foot. He already had order for calcium alginate drsg and then an order was obtained for unna boot. My supervisor has a note on the treatment sheet to wrap wounds with unna boot , put alginate drsg on top of boot to absorb drainage, and cover w rolled gauze. I only have to do this Tx every other week. The last time I had to do it the drsg was wrapped around the foot ulcer , then cut. Then started back rt above ankle to cover wound with the unna boot against the draining wound. When i reapplied i put alginate to wound and applied unna boot from base of toes to just below knee. She told me i was wrong. Opinions Please!
