If a person's glomerular filtration rate (GFR) significantly decreases due to chronic kidney disease, which consequence follows regarding electrolyte and water balance?

💡 Explanation

When GFR decreases, the kidneys filter less fluid and electrolytes; therefore, less sodium and water are excreted, leading to fluid retention and edema because the body's ability to maintain fluid balance is compromised, rather than increasing electrolyte excretion. Therefore, fluid retention results.
