In Ms. Procinski's case, which urinary finding is noted that supports suspicion of nephrotic syndrome?

• A. Hematuria
• B. Foamy urine
• C. Dark urine
• D. Cloudy urine

Answer: (B)

Foamy urine is a classic clue for nephrotic syndrome because of heavy protein loss in the urine (proteinuria). When large amounts of protein spill into the urine, it lowers the surface tension and makes the urine appear foamy or frothy after it’s passed. This foamy appearance directly reflects the hallmark feature of nephrotic syndrome. Other urinalysis findings like blood, darkness, or cloudiness can occur for different reasons (blood from glomerular bleeding, concentrated urine, or infection), and are not as specific to nephrotic syndrome.
