Right upper quadrant marking indicates which ostomy types?

• A. Transverse or ascending colostomy
• B. Descending colostomy
• C. Ileostomy
• D. Urostomy

Answer: (A)

Right upper quadrant markings align with the parts of the bowel that sit there anatomically—the transverse colon crosses the upper abdomen and the ascending colon lies on the right side. When a stoma is planned from those segments, the typical site ends up in the right upper quadrant, so marking in that area points to a transverse or ascending colostomy. A descending colostomy sits on the left side, not the right upper area. Ileostomies and urostomies are usually placed lower in the abdomen, often in the right lower quadrant or nearby, rather than in the right upper quadrant. So the right upper quadrant marking most commonly indicates a transverse or ascending colostomy.
