I know that in the "related to" aspect of the Nursing Diagnosis of a care plan, you are NOT supposed to use medical diagnostic terminology. ex - you can't say "such and such related to colon cancer". Well, what about Pressure Ulcer Staging? Is that a strictly medical diagnosis? Could a nurse, for example, put "Impaired skin integrity related to Pressure Ulcer Stage II" in the nursing diagnosis? My guess is no, because that just seems too easy - but in my textbook, it says that nurses can "assess and stage pressure ulcers". So that kind of threw me for a loop. Any thoughts? thank you!
