A nurse is caring for a client in the emergency department with a diagnosis of renal calculi. Which of the following areas of the renal system do most renal calculi begin forming?
Bladder
Renal papilla
Ureter
Urethra
The Correct Answer is B
Choice A reason: The bladder is not where renal calculi typically begin to form; it is where they may end up if they travel down from the kidneys.
Choice B reason: Renal calculi commonly begin forming at the renal papilla, which is part of the kidney where urine collects before it flows into the ureter.
Choice C reason: The ureter is not the typical starting point for the formation of renal calculi, though stones can travel through it.
Choice D reason: The urethra is not a common site for the formation of renal calculi; it is the duct through which urine is discharged.

Correct Answer is C
Explanation
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.
Correct Answer is B
Explanation
Choice A reason: Taking 3,000 mg of vitamin C daily is not recommended as it may increase the risk of calcium oxalate stones due to possible conversion of vitamin C to oxalate.
Choice B reason: Drinking 3 L of fluid every day is advised to prevent kidney stones by diluting the urine and reducing the concentration of stone-forming substances.
Choice C reason: Eating 12 oz of animal protein daily is excessive and can increase the risk of kidney stones due to higher excretion of calcium and oxalate.
Choice D reason: Restricting calcium intake to one serving per day is not recommended as a normal calcium intake is necessary to bind oxalate in the gut and reduce oxalate absorption.
