Prerenal azotemia and acute renal failure
Long-Term Care Nursing Advisor, October 5, 2007
Prerenal azotemia is the most common form of kidney failure seen in hospitalized patients. Long-term care facility residents who are hospitalized are commonly diagnosed with prerenal azotemia, particularly if they have been diagnosed with dehydration. Occasionally, a resident will be diagnosed with acute renal failure (ARF), despite having no known history of renal disease. Prerenal azotemia causes about 50%-80% of all ARF cases. Inadequate perfusion of the kidneys occurs as a result of extracellular fluid volume depletion or cardiovascular disease.
