A patient has glomerular damage with ankle edema and persistent frothy urine. Which finding most directly indicates increased loss through the filtration barrier?
Correct answer: A. Protein in the urine
- A. Protein in the urine
- B. Urobilinogen in the urine
- C. Concentrated urine
- D. Increased urinary frequency
Explanation
Glomerular damage can allow albumin to pass into urine, producing proteinuria and contributing to edema through reduced plasma oncotic pressure. The other findings do not specifically indicate loss of large plasma proteins through the glomerulus.

About Urinary System
The urinary system includes the kidneys, ureters, urinary bladder and urethra, with emphasis on nephron structure and urine formation. It explains glomerular filtration, tubular reabsorption, tubular secretion, water and electrolyte regulation, acid base balance, and the roles of ADH and aldosterone in maintaining homeostasis.
