Which statement is true about ostomy appliance requirements?

• A. Must be waterproof
• B. Must be transparent
• C. Must be disposable after one use
• D. Be odor proof

Answer: (D)

Odor control is a central requirement of an ostomy appliance because it directly affects daily life, comfort, and social confidence. Appliances are designed to seal and contain contents securely, with features like tight closures and odor-reducing filters so gases and smells don’t escape into the environment. This focus on odor containment helps users feel more normal in public and reduces anxiety about leaks or smells during activities.

While other features exist—such as being waterproof for swimming or weather resistance, or being transparent for easy inspection, or being disposable after one use—these are not universal requirements. Some devices are reusable or designed for privacy with opaque materials, and not every scenario demands a waterproof product. The most essential, consistent need across ostomy care is minimizing odor, which is why “Be odor proof” is the true statement.
