In caring for a child with nephrotic syndrome, which intervention will be most important to be included in the child's plan of care?

A. Weighing the child daily on the same scale is critical for monitoring fluid retention and managing edema, which are primary concerns in nephrotic syndrome. B. Testing urine for glucose levels is not a routine part of nephrotic syndrome management, as glucose levels are not typically affected by this condition. C. Increasing fluid intake is not advisable in nephrotic syndrome if there is significant edema; fluid management must be tailored to the child's condition. D. While ambulation is beneficial, it is not as critical as daily weight monitoring in managing nephrotic syndrome.
