The patient is a 48-year-old man with acute renal failure. Which of the following is the most common clinical manifestation of acute renal failure?
A) Decrease in BUN
B) Anuria
C) Oliguria
D) Decrease in serum creatinine
Ans: C
Feedback: Acute renal failure manifests as oliguria, anuria, or normal urine volume. Oliguria (less than 400 mL/d of urine) is the most common clinical situation seen in acute renal failure; anuria (less than 50 mL/d of urine) and normal urine output are not as common. Regardless of the volume of urine excreted, the patient with acute renal failure experiences rising serum creatinine and BUN levels and retention of other metabolic waste products (azotemia) normally excreted by the kidneys.
