Final answer:
For a client with renal failure on a low phosphate diet, the nurse would teach them to restrict dairy products, which are high in phosphate.
Step-by-step explanation:
When teaching a client with renal failure about a low phosphate diet, the nurse would instruct the client to restrict dairy products. Dairy products are known to be high in phosphate and therefore should be limited in the diet of someone with renal failure. Foods such as green, leafy vegetables, high-fat foods, and fruits and juices are not as high in phosphate compared to dairy products. It's important to include a variety of vegetables in your diet, but particular attention should be given to foods known to be rich in phosphates like dairy products when managing conditions like renal failure.
