A nurse is reinforcing teaching for a client who has a new ascending colostomy. Which of the following comments by the client indicates an understanding of the teaching?

Rationale: A. "I will irrigate the colostomy every day.": Colostomy irrigation is used for descending or sigmoid colostomies to regulate bowel movements. It is not recommended for ascending colostomies because the stool is too liquid and unpredictable for effective irrigation. B. "I will notify my doctor if the stoma starts to look purple.": A healthy stoma should be pink or red and moist. A purple or dusky appearance suggests compromised blood flow or ischemia and should be reported to the provider immediately as it may indicate a serious complication. C. "I should expect my stool to be formed.": Stool from an ascending colostomy is generally liquid to semi-liquid due to the location in the digestive tract. Formed stool is more typical of descending or sigmoid colostomies, not ascending ones. D. "I will no longer be able to eat nuts.": While some clients may choose to avoid certain foods based on personal tolerance, there is no absolute dietary restriction against nuts for colostomy clients unless otherwise advised.
