D) 9.3 mg/dL

Question

Quizplus · Accepted Answer

BUN (Blood Urea Nitrogen) measures the nitrogen part of urea in the blood. Urea is roughly 46% nitrogen, so to find the total urea concentration from BUN, you divide the BUN value by 0.46. For a BUN of 10 mg/dL, the urea concentration is 10 mg/dL / 0.46 = approximately 21.7 mg/dL, which is closest to option B, 21.4 mg/dL.
