The nurse notes that a client who is scheduled for surgery the next morning has an elevated blood urea nitrogen (BUN) level. Which condition is most likely to have contributed to this finding? A. Myocardial infarction 2 months ago B. Anorexia and vomiting for the past 2 days C. Recently diagnosed type 2 diabetes mellitus D. Skeletal traction for a right hip fracture - ANSWER: Correct Answer: B Rationale: The blood urea nitrogen (BUN) level indicates the effectiveness of the kidneys in filtering waste from the blood. Dehydration, which could be caused by vomiting, would cause an increased BUN level. Option A would affect serum enzyme levels, not the BUN level. Option C would primarily affect the blood glucose level; renal failure that could increase the BUN level would be unlikely in a client newly diagnosed with type 2 diabetes. Effects of option D might affect the complete blood count (CBC) but would not directly increase the BUN level.
