Which of the following statements by the client indicates effective understanding of how to reduce odor from a colostomy?

Rationale: A. Applying oils directly to the stoma is unsafe and can irritate the skin or damage the stoma tissue. Essential oils are not recommended for odor control in colostomy care. B. Emptying the colostomy pouch before it becomes too full helps prevent gas buildup and bacterial overgrowth, which are the primary causes of odor. This is a safe and effective strategy to control odor and maintain hygiene. C. Ventilating the bathroom may help with room air quality, but it does not address the source of odor, which comes from the stoma and pouch. Proper pouch management is more effective than relying on ventilation alone. D. High-fiber foods are important for nutritional balance and bowel function. While certain foods can contribute to gas or odor, eliminating fiber entirely is unnecessary and potentially harmful. Patients are usually taught which specific foods may increase odor rather than avoiding fiber altogether.
