A nurse is assessing a client's risk factors for chronic renal failure. Which medical condition should the nurse recognize as a significant risk factor for kidney disease?

A. Incorrect. Calcitriol is not given to enhance appetite or improve nutrition. Its primary role is in regulating calcium and phosphate levels.

B. Incorrect. Calcitriol does not directly impact urine output or prevent kidney stones.

C. Incorrect. While some medications may be prescribed to manage blood pressure in chronic renal failure, calcitriol is not one of them.

D. Correct. Calcitriol is the active form of vitamin D and plays a crucial role in regulating calcium and phosphate levels in the body. It helps maintain bone health by promoting the absorption of calcium from the digestive tract and preventing bone demineralization.

A. Incorrect. Applying compression stockings may help reduce swelling but does not address the underlying cause. Additionally, compression stockings should not be used if the client has arterial insufficiency.

B. Incorrect. Elevation may provide temporary relief from swelling, but it does not address the underlying cause of fluid retention

in chronic renal failure.

C. Correct. The nurse should measure the client's blood pressure and pulse rate to assess for fluid overload and possible hypertension, which can be associated with chronic renal failure.

D. Incorrect. Assessing the client's daily protein intake is not the priority when the client presents with swelling in the ankles and legs. Fluid retention is a more immediate concern that requires assessment and intervention.
