The practical nurse notes facial swelling and foamy urine in Ms. Procinski. Which condition is most consistent with these findings?

• A. Urinary tract infection
• B. Pyelonephritis
• C. Nephrotic syndrome
• D. Acute glomerulonephritis

Answer: (D)

The main idea here is that facial swelling with foamy urine points to heavy protein loss in the urine, which lowers plasma albumin and causes edema. This pattern is classic for nephrotic syndrome. When protein loss is that large (proteinuria), urine becomes foamy, and the decreased oncotic pressure in the blood leads to fluid leaking into tissues, producing facial and generalized edema. Nephrotic syndrome also characteristically includes very high protein in the urine, low serum albumin, and often high lipid levels. In contrast, acute glomerulonephritis usually shows blood in the urine (hematuria) with red blood cell casts, possible hypertension, and reduced urine output, rather than predominantly foamy urine from heavy proteinuria. Urinary tract infection or pyelonephritis can cause burning on urination, dysuria, fever, and flank pain, but they don’t typically produce the heavy proteinuria and edema pattern seen with nephrotic syndrome. So, the presentation most consistent with these findings is nephrotic syndrome.
