When would tracing be preferred over a pre-cut measuring card?

• A. When stoma output is high
• B. For sizes not present on the card or very irregular shapes
• C. When stoma is healthy
• D. For round stomas only

Answer: (B)

Tracing is used when the opening needed for the appliance isn’t available on the pre-cut card or when the stoma shape is irregular. A tracing lets you recreate a custom opening that follows the exact contour of the stoma, ensuring a snug seal without constricting the stoma. This reduces leakage and skin irritation because the barrier opening matches the unique size and shape rather than forcing a standard size that may be too large, too small, or misshapen.

In contrast, a pre-cut measuring card works well when the stoma size is one of the standard openings and the stoma has a regular, typical shape. If the stoma is healthy and round with a size that matches a card opening, the card is quick and reliable. If the stoma shape is very irregular or the size isn’t represented on the card, tracing provides the precise customization needed.
