Right lower quadrant marking is associated with which ostomy categories?

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

Answer: (A)

Right lower quadrant marking is typically used for ostomies that exit the small intestine or urinary system, because these stomas are commonly brought to the right lower abdomen for ease of access, fit against the belt line, and to minimize interference with other abdominal structures. Ileostomies and urostomies are classic examples, since both involve bringing a bowel or urinary conduit to the abdominal wall in that area. Continent diversions, which use a catheterizable channel often placed in the same region for practical access, also fall into this quadrant.

In contrast, sigmoid colostomies are usually placed in the left lower quadrant because the sigmoid colon resides there, and transverse colostomies are often higher up on the abdomen rather than in the right lower quadrant. So the combination of ileostomy, urostomy, and continent diversions best aligns with right lower quadrant marking.
