A nurse is educating a client about the impact of cardiovascular disease on kidney health. Which statement made by the client demonstrates understanding?

A. Incorrect. Dairy products are high in potassium and should be limited in clients at risk for hyperkalemia.

B. Incorrect. Fruits and vegetables are also high in potassium and should be limited in clients with chronic renal failure and hyperkalemia risk.

C. Correct. Nuts and seeds are rich sources of potassium and should be restricted in the diet of clients at risk for hyperkalemia.

D. Incorrect. Poultry is a good protein source, but the type of protein is not the main concern for clients at risk for hyperkalemia; it is the overall potassium content of the diet that needs to be reduced.

A. Incorrect. Converting the creatinine level to micromoles per liter is not necessary for the GFR calculation.

B. Incorrect. While a 24-hour urine sample can be used to measure creatinine clearance, it is not required for the GFR calculation, which can be estimated using formulas.

C. Incorrect. Calculating the body surface area is not necessary for the GFR calculation.

D. Correct. The GFR can be estimated using formulas that include the serum creatinine level, such as the Modification of Diet in Renal Disease (MDRD. formula or the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
