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. In chronic renal failure, the kidneys may have difficulty processing excess protein, so protein intake should be limited to reduce the workload on the kidneys.

B. Correct. Limiting fluid intake is crucial in managing chronic renal failure. The kidneys' reduced ability to filter waste products can lead to fluid retention and electrolyte imbalances, so restricting fluid intake helps prevent overload and complications.

C. Incorrect. In chronic renal failure, high-potassium foods should be limited to prevent hyperkalemia, a condition in which potassium levels in the blood become too high.

D. Incorrect. Foods high in phosphorus should be restricted in chronic renal failure because the kidneys may have difficulty excreting excess phosphorus, leading to hyperphosphatemia, which can contribute to bone and mineral disorders.

A. Incorrect. Encouraging the client to drink 3 liters of fluid daily may be excessive and can contribute to fluid overload in individuals on hemodialysis. Fluid intake needs to be limited and closely monitored.

B. Correct. Monitoring the vascular access site is crucial to detect early signs of infection or clotting, which can lead to serious complications such as sepsis or thrombosis.

C. Incorrect. Phosphate binders are used to control phosphate levels in the blood and are generally taken with meals, not specifically before hemodialysis sessions.

D. Incorrect. Promoting a high-potassium diet is not appropriate for individuals on hemodialysis, as it can lead to hyperkalemia. Clients on hemodialysis typically need to restrict potassium intake.
