A nurse is providing dietary teaching to a client who has a history of recurring calcium oxalate kidney stones. Which of the following instructions should the nurse include in the teaching?
 

Choice A reason: A diet high in calcium oxalate-rich foods should be avoided as it can contribute to the formation of calcium oxalate stones.

Choice B reason: Continuing prescribed gout medication is important, but it does not directly prevent the formation of renal calculi unless the medication is specifically for reducing uric acid levels.

Choice C reason: Drinking plenty of fluids, especially water, is one of the most effective ways to prevent the recurrence of renal calculi by diluting the urine and reducing the concentration of stone-forming minerals.

Choice D reason: A diet high in purine-rich foods can increase the risk of uric acid stones and should be avoided, especially in patients with gout and a history of renal calculi.

Choice A reason: The end of a menstrual period is not relevant to the intravenous pyelogram procedure.

Choice B reason: An allergy to shellfish is important to report as the contrast dye used in an intravenous pyelogram may contain iodine, which can cause an allergic reaction in individuals with shellfish allergies.

Choice C reason: Drinking fluids is generally encouraged to prevent kidney stones and is not a concern for the provider.

Choice D reason: Painful and red-tinged urination is a symptom of kidney stones but does not need to be reported unless it is a new or worsening symptom.
