Acute Kidney Failure
Acute Kidney Failure ( 49 Questions)
Incorrect. Increased glomerular filtration rate (GFR) would lead to increased urine output, not decreased urine output.
Incorrect. Obstruction of the urethra would cause postrenal acute renal failure and may lead to urinary retention, but it would not cause decreased urine output in prerenal or intrinsic acute renal failure.
Correct. In prerenal and intrinsic acute renal failure, impaired blood flow to the kidneys reduces the perfusion of nephrons, leading to decreased urine output.
Incorrect. Excessive fluid intake may contribute to fluid overload and decreased urine output in prerenal acute renal failure, but it is not the primary pathophysiological process that leads to decreased urine output.
A) Incorrect. Increased glomerular filtration rate (GFR) would lead to increased urine output, not decreased urine output.
B) Incorrect. Obstruction of the urethra would cause postrenal acute renal failure and may lead to urinary retention, but it would not cause decreased urine output in prerenal or intrinsic acute renal failure.
C) Correct. In prerenal and intrinsic acute renal failure, impaired blood flow to the kidneys reduces the perfusion of nephrons, leading to decreased urine output.
D) Incorrect. Excessive fluid intake may contribute to fluid overload and decreased urine output in prerenal acute renal failure, but it is not the primary pathophysiological process that leads to decreased urine output.
