Which foods should a client diagnosed with calcium oxalate renal calculi avoid? Select all that apply.

A client diagnosed with calcium oxalate renal calculi should focus on avoiding foods that are high in oxalates, as these can contribute to the formation of kidney stones. Tea, particularly black tea, contains significant amounts of oxalate, making it a suitable choice to eliminate from the diet for individuals with this condition.

Spinach and rhubarb are also high in oxalates and would typically be recommended for avoidance among clients dealing with calcium oxalate stones. While white rice is low in oxalates and generally does not contribute to stone formation, it is not high in oxalate content like the other food items. Therefore, the focus on tea, along with spinach and rhubarb, is crucial for managing and preventing further complications in patients with calcium oxalate renal calculi.
