Which observation related to a newly created transverse colostomy requires immediate notification of the health care provider?

Purple discoloration of the stoma is concerning as it indicates compromised blood supply to the area, which could lead to necrosis of the stoma tissue. A healthy stoma should appear beefy red and shiny, reflecting good blood flow and health of the tissue. When a stoma appears purple or dusky, it signifies that the tissue may not be receiving adequate oxygenation, raising the risk of tissue death. This situation demands immediate attention from a healthcare provider to assess the potential need for intervention to restore blood flow or to consider further management of the stoma to prevent serious complications.

In contrast, a beefy red and shiny stoma is an expected finding indicating good perfusion, while skin excoriation around the stoma, though problematic, can often be managed through proper skin care practices. Semi-formed stool in the ostomy pouch is also normal for a transverse colostomy, which typically produces more formed stools than other types of colostomies.
