A nurse is assessing a client with nephrotic syndrome and notes frothy, foamy urine output. What is the rationale for this characteristic urine appearance?

A. Incorrect. While some clients may be at increased risk of certain infections, avoiding close contact with family members is not practical and not recommended in general.

B. Correct. Good hand hygiene is essential in reducing the risk of infections in clients with nephrotic syndrome, as they are immunocompromised due to protein loss in the urine. Regular handwashing with soap and water, especially before meals and after using the bathroom, can help prevent the spread of pathogens.

C. Incorrect. Avoiding outdoor activities and crowded places is not necessary for all clients with nephrotic syndrome and may negatively impact their quality of life.

D. Incorrect. While physical activity is generally beneficial for overall health, it is not directly related to enhancing the immune system's response in clients with nephrotic syndrome.

A. Incorrect. Increased urine output and dehydration are not common side effects of corticosteroid therapy. Instead, clients may experience fluid retention and edema due to the medication's effects.

B. Correct. Corticosteroids can cause increased appetite, leading to weight gain, which is a common side effect that clients should be aware of.

C. Incorrect. Frequent bruising and prolonged bleeding are not typical side effects of corticosteroids. Instead, clients on corticosteroid therapy may experience increased susceptibility to infections and impaired wound healing.

D. Incorrect. Corticosteroids are more likely to cause fluid retention and increased blood pressure, leading to potential hypertension, rather than low blood pressure and dizziness.
