Extended wear barriers work based on what?

• A. They rely on moisture absorption
• B. They need good initial pressure only
• C. They rely on chemical adhesives
• D. They require frequent changes

Answer: (B)

Extended wear barriers stay in place mainly because of a strong initial seal created when they’re applied. Applying steady, even pressure around the stoma as you place the barrier helps the adhesive bond firmly to the skin right from the start, forming a leak-proof seal that can withstand movement and moisture over several days. The key idea is that proper initial contact sets up the barrier for long wear, rather than relying on moisture absorption, a special chemical adhesive effect, or frequent changes. If the barrier is not pressed firmly enough at first, tiny gaps can form and leaks or skin irritation may occur, even if the skin looks intact later.
