Question

The nurse reviewing laboratory reports on kidney function identifies a result that suggests decreased renal function, which is:

a. blood urea nitrogen (BUN), 10.5 mg/dL.
b. creatinine, 0.6 mg/dL.
c. BUN, 15 mg/dL.
d. creatinine, 2.0 mg/dL.

Answer 1

A result of BUN, 15 mg/dL suggests decreased renal function, while a result of creatinine, 2.0 mg/dL falls within the normal range and does not suggest decreased renal function.

Step-by-step explanation:

Based on the normal ranges for blood urea nitrogen (BUN) and creatinine, a result of BUN, 15 mg/dL suggests decreased renal function. The normal range for BUN is 8-20 mg/dL, and a value of 15 mg/dL falls within this range. On the other hand, the normal range for creatinine in males is 0.8-1.2 mg/dL and in females is 0.6-0.9 mg/dL. Therefore, a result of creatinine, 2.0 mg/dL falls within the normal range and does not suggest decreased renal function.
