For blood urea nitrogen (BUN) and creatinine values:
A) serum creatinine is a protein produced in the kidneys.

D) BUN values that are below normal indicate renal failure.

Question

Quizplus · Accepted Answer

BUN and serum creatinine are waste products filtered out of the blood by the kidneys. Elevated levels of these substances can indicate that the kidneys are not functioning properly, which is a sign of renal failure. Serum creatinine is actually a waste product of muscle metabolism, not produced in the kidneys. Urea is a waste product of protein metabolism, not carbohydrate metabolism. Lastly, BUN values that are below normal do not typically indicate renal failure; instead, they might be associated with other conditions, such as liver disease or malnutrition.
