A nurse has taught a client about dietary changes that can reduce the chances of developing cancer. What statement by the client indicates the nurse needs to provide additional teaching.

Choice A rationale Vitamins A and C function as powerful antioxidants, which protect cellular DNA from damage by free radicals, a process that can lead to cancer development. Consuming foods rich in these vitamins, such as fruits and vegetables, is a key dietary recommendation for cancer prevention. Choice B rationale Processed meats, such as bacon, are typically high in nitrites and nitrates, which can form carcinogenic N-nitroso compounds in the body. Limiting the intake of processed and preserved meats is a scientifically supported dietary modification to reduce cancer risk. Choice C rationale Red meat, particularly when consumed in large amounts or cooked at high temperatures, has been linked to an increased risk of colorectal cancer, possibly due to compounds like heme iron and heterocyclic amines. The client's statement indicates a lack of understanding that limiting red meat is recommended. Choice D rationale A diet rich in vegetables, fruits, and high-fiber grains provides numerous protective factors, including antioxidants, phytochemicals, and fiber. Fiber helps accelerate the transit time of waste, reducing contact time between potential carcinogens and the bowel wall, thus lowering cancer risk.
