A nurse is reinforcing teaching with another nurse about how to change an ostomy appliance for a client who has a sigmoid colostomy. Which of the following instructions should the nurse include in the teaching?

Create an opening on the skin barrier that is 1.27 cm (0.5 in) larger than the client's stoma: It is important to ensure that the opening in the skin barrier is slightly larger than the stoma to prevent irritation or pressure on the stoma. This allows for proper fit and helps maintain a secure seal. Use a mild, non-irritating soap or specifically designed ostomy cleanser to clean the skin around the client's stoma: Harsh soaps or cleansers can irritate the skin around the stoma. Using a moisturizing or gentle cleanser helps maintain the integrity of the skin and reduces the risk of irritation or breakdown. Empty the client's ostomy pouch before removing the skin barrier: It is important to empty the ostomy pouch to prevent leakage or spillage during the appliance change. This helps maintain cleanliness and prevents potential contamination or soiling of the surrounding area. The timing of the ostomy appliance change is not specified in the given options. The appropriate timing for changing the ostomy appliance depends on the individual client's needs and preferences. It may be helpful to consider factors such as the client's comfort, schedule, and amount of output in determining the best time for the appliance change. This instruction is not necessary for the teaching session.
