A nurse is providing teaching to a patient who has nephrotic syndrome. The nurse should recognize that which of the following patient statements indicates a need for further teaching?

Choice A reason: Increasing sodium intake is contraindicated in nephrotic syndrome. Excess sodium exacerbates fluid retention and edema, which are hallmark symptoms of the condition. Patients are typically advised to follow a low-sodium diet to manage blood pressure and swelling. Choice B reason: Proteinuria is a defining feature of nephrotic syndrome. The glomerular damage leads to significant protein loss in the urine, which is accurate and expected. Choice C reason: Facial edema, especially periorbital swelling, is a common early symptom of nephrotic syndrome. This statement reflects appropriate understanding of the condition. Choice D reason: A kidney biopsy is often performed to determine the underlying cause of nephrotic syndrome and guide treatment. This is a standard diagnostic approach and does not indicate misunderstanding.
