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. "Empty the ostomy pouch when it becomes one-third full of contents.": It is important to empty the ostomy pouch when it is about one-third full to prevent leakage and pressure on the stoma. This helps avoid skin irritation and maintain comfort. B. "Expect the stoma to turn a purple-blue color as it heals.": A stoma should be a reddish-pink color. A purple or blue color indicates poor circulation and may signal complications such as ischemia, which requires immediate attention. C. "Cut the opening of the pouch an inch larger than the stoma.": The opening of the ostomy pouch should be cut about one-quarter to one-half inch larger than the stoma to prevent irritation or pressure on the stoma. This ensures a good fit and reduces risk of skin damage. D. "Place a piece of gauze over the stoma while changing the pouch.": Placing gauze over the stoma during pouch changes protects the skin around the stoma from contact with stool and absorbs any drainage. E. "Use povidone-iodine to clean around the stoma.": Povidone-iodine is too harsh for cleaning the stoma area and may cause skin irritation. The recommended cleaning solution is warm water and mild soap, followed by proper drying, to avoid skin damage and infection.
