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?

A. "I will no longer be able to eat nuts.": While some high-fiber or hard-to-digest foods may cause temporary blockage or discomfort, a complete avoidance of nuts is not necessary. Clients can often reintroduce small amounts once they tolerate the diet, so this statement does not reflect full understanding. B. "I will irrigate the colostomy every day.": Daily irrigation is not typically required for an ascending colostomy because the stool in this section of the colon is usually liquid and frequent. Irrigation is more appropriate for descending or sigmoid colostomies to regulate stool output. C. "I should expect my stool to be formed.": An ascending colostomy produces liquid to semi-liquid stool due to the short transit time and limited water absorption in this portion of the colon. Expecting formed stool indicates a misunderstanding of normal stoma output. D. "I will notify my doctor if the stoma starts to look purple.": A purple or dusky stoma can indicate compromised blood flow, ischemia, or necrosis, which is a medical emergency. Recognizing this as abnormal demonstrates proper understanding of stoma monitoring and when to seek immediate medical attention.
