A nurse is completing discharge teaching about ostomy care with a client who has a new stoma. Which of the following instructions should the nurse include in the teaching? (Select all that apply)

A. The opening of the pouch should be cut about 1/8 of an inch larger than the stoma to ensure a proper fit without restricting blood flow or irritating the stoma. B. Placing a gauze over the stoma during a pouch change helps to absorb any discharge and keep the area clean while preparing the new appliance. C. Povidone-iodine should not be used to clean around the stoma, as it can irritate the skin. The skin should be cleaned with mild soap and water or a recommended stoma cleanser. D. A stoma that turns purple-blue is a sign of impaired blood flow and requires immediate medical attention. A healthy stoma should appear pink or red and moist. E. The ostomy pouch should be emptied when it is about one-third full to prevent leakage, odor, and unnecessary pressure on the stoma.
