The client with uric acid nephrolithiasis should have a diet low in which of the following?

A diet low in methionine is beneficial for clients with uric acid nephrolithiasis because methionine is an amino acid that can contribute to the formation of uric acid. Uric acid nephrolithiasis, or kidney stones formed from uric acid, can be exacerbated by high levels of uric acid in the body. Therefore, limiting methionine intake helps to decrease uric acid production, thereby potentially reducing the risk of stone formation.

While protein might also be considered in relation to properties affecting uric acid levels, the primary concern with uric acid stones specifically relates to methionine. As for potassium and calcium, these nutrients are generally not restricted in the context of uric acid nephrolithiasis, and may even be important for overall health. Reducing methionine while ensuring adequate intake of other nutrients is crucial for managing the condition effectively.
