Which item is an ostomy accessory used to help create a skin barrier seal?

• A. Skin barrier rings
• B. Pouch vent
• C. Deodorizers
• D. Ostomy powder

Answer: (A)

The key idea is that a reliable skin barrier seal around the stoma is achieved by filling gaps and smoothing irregularities in peristomal skin. Skin barrier rings are flexible, thin rings placed around the stoma (either around the skin opening or beneath the barrier) to fill creases and contour differences. This creates a continuous contact surface for the adhesive barrier, helping prevent leaks and protecting skin from moisture and effluent. They come in various sizes and can be used with most pouching systems to adapt to individual anatomy and improve seal integrity.

Pouch vents are designed to let gas escape from the pouch, not to improve the seal at the skin. Deodorizers target odor control and do not affect how the barrier adheres to skin. Ostomy powder is used to dry or protect skin and can aid adhesion in moist conditions, but it does not create the sealing interface around the stoma like a barrier ring does.
