A) Correct. Diuretics are commonly used to manage edema in clients with nephrotic syndrome. They help increase urine output and reduce fluid retention, which can alleviate severe edema and fluid overload.

B) Incorrect. Restricting fluid intake is not typically recommended for clients with nephrotic syndrome, as it may lead to dehydration and worsen the hypoalbuminemia.

C) Incorrect. While adequate protein intake is essential, a high-protein diet may not be appropriate for clients with nephrotic syndrome due to increased protein loss in the urine.

D) Incorrect. Monitoring blood glucose levels is important, but it is not directly related to managing edema and hypoalbuminemia in nephrotic syndrome.
