Ostomy Management Specialist (OMS) Certification Practice Exam

Which of the following is a function of the skin barrier in ostomy care?

Increase ostomy output Block odor entirely Improve filtration Protect the skin

Correct Answer:

Protect the skin

Explanation:

The main idea here is that the skin barrier exists to protect the skin around the stoma. It forms a protective layer and a seal with the ostomy pouching system, shielding peristomal skin from the caustic components in the stoma output, such as digestive enzymes and moisture. This prevents irritation and skin breakdown, helping the skin stay healthy so it can tolerate the appliance and remain leak-free. Odor control isn’t the barrier’s primary job, and it doesn’t change how much output you have or how well the system filters. The barrier’s purpose is safeguarding the skin integrity and supporting a proper seal.
