A nurse is assessing a client who had a colostomy 24 hr ago. Which of the following findings is the nurse's priority?

A. The client reports a pain level of 6 on a scale from 0 to 10: Moderate pain is expected after surgery and should be managed, but it is not immediately life-threatening or the highest priority. B. The client refuses to look at the colostomy: Emotional adjustment is important, but this does not pose an immediate physical risk to the client and can be addressed over time with support and education. C. The colostomy has had no output: It is common for a new colostomy to have delayed output within the first 24 hours postoperatively, so this finding is expected and not immediately concerning. D. The stoma appears dark purple in color: A dark purple stoma indicates compromised blood flow or ischemia, which is a medical emergency requiring immediate intervention to prevent tissue necrosis and further complications.
