Right lower quadrant marking corresponds to which ostomy types?

• A. Ileostomy, urostomy, and continent diversions
• B. Sigmoid colostomy
• C. Transverse colostomy
• D. Ileostomy only

Answer: (A)

Right lower quadrant marking is used for stomas that come from the ileum or urinary diversion, because these ostomies exit through the right lower abdomen and are placed there for best appliance fit and tract alignment. An ileostomy uses the ileum, a urostomy (ileal conduit) uses an ileal segment to drain urine, and continent diversions rely on an ileal reservoir with a stoma in that same area. Sigmoid colostomies come from the sigmoid colon, which sits on the left side of the abdomen, so they’re typically marked in the left lower quadrant. Transverse colostomies are usually placed higher up, often in the upper abdomen or midline, depending on anatomy. So the right lower quadrant marking aligns with ileostomy, urostomy, and continent diversions, not sigmoid or transverse colostomies.
