A patient with a colostomy continues to worry about odor. What instruction should a nurse provide to allay this concern?

Rationale: A. Piercing the colostomy pouch is dangerous and can lead to leakage, contamination, and infection. It also defeats the purpose of the pouch, which is to contain waste and control odor. Modern pouches often have built-in filters to safely release gas without allowing odor to escape. B. Tight-fitting underwear does not prevent odor. Instead, it can trap gas and moisture, potentially increasing odor and causing skin irritation or breakdown around the stoma. Properly fitting undergarments are important for comfort but are not effective for odor control. C. While older methods suggested rinsing pouches with vinegar, this is unnecessary with modern disposable or closed-system pouches. Improper rinsing can compromise the pouch seal, reduce its effectiveness, and irritate the skin. D. Maintaining proper hygiene around the stoma is the safest and most effective way to control odor. This includes regularly emptying the pouch before it becomes too full, gently cleaning the peristomal skin, changing the pouch as needed to prevent leaks and bacterial growth, and using deodorizing drops or odor-filter pouches if recommended. Proper hygiene reduces bacterial growth, minimizes odor, prevents skin irritation, and helps alleviate patient anxiety, improving quality of life.
