Pressure injuries of mucosa are related to damage from what?

• A. Stoma medical device
• B. Bowel infection
• C. Poor hydration
• D. Dietary fiber

Answer: (A)

Pressure injuries to the mucosa occur from mechanical compression by the ostomy device. When the stoma appliance or its barrier fits too tightly, or the aperture is improperly sized or misaligned, the mucosal tissue inside and around the stoma is pressed against the device. This sustained pressure reduces blood flow, leading to ischemia and tissue damage on the mucosa. Other factors like bowel infection, poor hydration, or dietary fiber affect stool or skin care but don’t cause a mucosal pressure injury from the device itself. Proper fit, correctly cut openings, and ensuring the device doesn’t press on the mucosa are key to preventing this injury.
