A patient with advanced kidney disease experiences a sharp drop in glomerular filtration rate. Which effect becomes most likely due to decreased filtration of proteins?

💡 Explanation

Reduced glomerular filtration prevents proteins from being effectively filtered out of the blood, because the filtration mechanism in the glomerulus is impaired. Therefore, plasma protein concentration increases, rather than the changes in red blood cell counts, interstitial fluid, or urea excretion.
