Chronic renal failure (CRF)_________.

Question

appears with normal CBC and serum electrolyte levels.
has a rapid and progressive onset.
is always the result of prerenal kidney injury.
follows five stages of progression with decreasing glomerular filtration rate

Answer 1

Chronic renal failure (CRF) follows five stages of progression with decreasing glomerular filtration rate.

This is the correct statement because CRF is typically classified into five stages based on the glomerular filtration rate (GFR), which reflects the severity of kidney dysfunction. The other statements provided are inaccurate. For example, CRF can have abnormal CBC and serum electrolyte levels, may have a slow and progressive onset rather than rapid, and is not always the result of prerenal kidney injury.
