Final answer:
To help mitigate the risk of colorectal cancer, the nurse should recommend adding cabbage to the diet, replacing butter with unsaturated oils, and reducing the consumption of red meat and processed meat.
Step-by-step explanation:
For a client with a family history of colorectal cancer, the nurse should recommend dietary alterations that can help mitigate the risk. One important alteration is to add cabbage to the diet. Cabbage is a good dietary source of insoluble fiber, which has been found to be associated with a decreased risk of colon cancer. The nurse should also recommend replacing butter with unsaturated oils, such as olive oil or canola oil. Unsaturated oils are healthier options that can help reduce the risk of colorectal cancer. Lastly, the nurse should advise the client to reduce the consumption of red meat and processed meat. Both red meat and processed meat have been linked to an increased risk of colorectal cancer.
