A nurse is assessing a toddler who has acute nephrotic syndrome. Which of the following findings should the nurse report to the provider?

A. Irritability is common in nephrotic syndrome due to discomfort and illness but is not as urgent as severe edema. B. Yellow nasal discharge is likely due to a concurrent cold and not a critical finding. C. Facial edema can be a sign of worsening nephrotic syndrome and should be reported to the provider, as it can indicate fluid retention or complications. D. Poor appetite is common in nephrotic syndrome but does not require immediate reporting unless there are other signs of deterioration.
