A client is recovering from an episode of urinary tract calculi. During discharge teaching, the client asks about dietary restrictions. In discussing food intake, the nurse should include which type of fluid limitation?

Choice A reason: Overall fluid intake should not be limited, but rather increased, for a client with urinary tract calculi. Increasing fluid intake can help flush out the stones and prevent new ones from forming. Choice B reason: Tea and hot chocolate should be limited, because they contain oxalates, which can increase the risk of calcium oxalate stones, the most common type of urinary tract calculi. Other foods high in oxalates include spinach, rhubarb, nuts, and chocolate. Choice C reason: Low-sodium soups are not a problem for a client with urinary tract calculi, unless they have other conditions that require sodium restriction, such as hypertension or heart failure. Sodium intake does not directly affect the formation of stones, but it can increase calcium excretion in the urine, which can contribute to calcium oxalate stones. Choice D reason: Citrus fruit juices are beneficial for a client with urinary tract calculi, because they contain citrate, which can prevent the crystallization of calcium and oxalate in the urine. Citrate can also help dissolve existing stones and prevent new ones from forming.
