Final answer:
The correct interpretation by the nurse would be A. This is a normal, expected event. After a colostomy, malodorous flatus or gas passing from the stoma is a common occurrence.
Step-by-step explanation:
The correct interpretation by the nurse would be A. This is a normal, expected event. After a colostomy, malodorous flatus or gas passing from the stoma is a common occurrence due to the change in the route of expulsion of gas. The colon now bypasses the rectum and anus, and the gas is expelled through the stoma.
It is important for the nurse to educate the client about the normal changes after colostomy and reassure them that this is not a cause for concern. Additionally, the nurse can provide information on strategies for odor control such as using odor-reducing pouches or deodorizing sprays.
