Question

How do you determine that a patient's oliguria is associated with acute renal failure (ARF)?

A. Specific gravity of urine at 3 different times is 1.010.
B. The serum creatinine level is normal.
C. The blood urea nitrogen (BUN) level is normal or below.
D. Hypokalemia is identified.

Answer 1

The diagnosis of acute renal failure (ARF) is made based on specific criteria and laboratory tests. In the case of oliguria associated with ARF, several factors can help determine if it is indeed caused by ARF. These factors include elevated serum creatinine levels, reduced urine output, elevated blood urea nitrogen levels, and identification of hypokalemia.

Step-by-step explanation:

The diagnosis of acute renal failure (ARF) is made based on specific criteria and laboratory tests. In the case of oliguria (decreased urine production) associated with ARF, several factors can help determine if it is indeed caused by ARF. These factors include elevated serum creatinine levels, reduced urine output, elevated blood urea nitrogen levels, and identification of hypokalemia. By assessing these factors along with other diagnostic tests, healthcare professionals can determine if a patient's oliguria is associated with ARF.
