Which of the following indicates a risk of infection in nephrotic syndrome?

In nephrotic syndrome, one of the significant concerns is the risk of infection, particularly due to the loss of immunoglobulins and other proteins in the urine, which compromises the immune system. The choice that highlights this risk is the need to monitor for upper respiratory infections.

Patients with nephrotic syndrome often have altered immune responses, making them more susceptible to infections. Upper respiratory infections are quite common in individuals with compromised immunity, and vigilant monitoring is essential to catch these infections early.

Other options, such as decreased urine output, increased appetite, and stable daily weights, do not directly indicate a risk of infection. Decreased urine output may suggest renal function issues or fluid overload, increased appetite typically indicates a good nutritional status, and stable daily weights are generally an indicator of stable fluid balance and nutrition rather than infection risk. Therefore, focusing on monitoring for upper respiratory infections is crucial for patients with nephrotic syndrome to prevent complications associated with infection.
