Question

Quizplus · Accepted Answer

1. This laboratory value indicates intrinsic renal failure because the osmolality is less than 350 mOsm/L.
2. In prerenal dysfunction, the urinalysis typically shows a concentrated urine with a high osmolality (500 mOsm/L) and a decreased urine sodium (<20 mmol/L).
3. This laboratory value indicates intrinsic renal failure because the urine sodium is greater than 40 mmol/L.
4. A fractional excretion of sodium (FENa) greater than 1% with granular casts and sediment is seen in intrinsic renal failure.
