Final answer:
The correct statement indicating understanding of discharge teaching for a child with nephrotic syndrome is checking the child's urine for protein. This reflects the key management aspect of monitoring proteinuria. Other options are incorrect and do not align with recommended care practices.
Therefore, option C is correct.
Step-by-step explanation:
The correct statement made by a parent of a child with nephrotic syndrome that indicates an understanding of discharge teaching is: "I should check his urine for protein when he goes to the bathroom." This statement demonstrates awareness that nephrotic syndrome can cause a significant amount of protein to leak into the urine, which is a crucial aspect of managing the condition at home. The other options provided do not reflect accurate or recommended practices for a child with nephrotic syndrome. For example, children with nephrotic syndrome, being at higher risk for infections due to immunosuppressive treatments, should not be given live vaccines like the measles vaccine immediately after discharge. They should remain on their medications as directed by their physician and not stop prematurely. Also, a low-protein diet is not recommended; instead, an adequate protein intake is usually encouraged to replace losses.
