A nurse is providing education to a client about acute renal failure. Which statement by the client indicates a correct understanding of the condition?

A. Incorrect. Decreased blood volume and hypovolemia may contribute to prerenal acute renal failure, but they are not the primary pathophysiological processes that lead to edema in acute renal failure.

B. Incorrect. Increased vascular permeability and leakage of fluid into tissues are not the primary mechanisms of edema in acute renal failure.

C. Correct. In acute renal failure, the impaired filtration and reduced excretion of fluid by the kidneys lead to fluid retention and edema in various parts of the body.

D. Incorrect. Excessive fluid intake and fluid overload may contribute to fluid retention and edema in prerenal acute renal failure, but they are not the primary pathophysiological process in acute renal failure.

A. Incorrect. While fluid restriction may be necessary in certain cases of acute renal failure, it should be prescribed and monitored by the healthcare provider based on the client's specific needs.

B. Incorrect. A high-protein diet can put additional strain on the kidneys, and it is not recommended for clients with acute renal failure.

C. Incorrect. Over-the-counter diuretics may not be safe for clients with acute renal failure and can lead to further electrolyte imbalances.

D. Correct. The nurse's best response is to encourage the client to follow their healthcare provider's instructions and avoid medications that may harm the kidneys. Compliance with prescribed treatment plans and avoiding nephrotoxic medications are essential to support kidney function and prevent further damage.
