The patient’s serum creatinine level is 7 mg/dL. The expected BUN level should be

  • A. 1 to 2 mg/dL.
  • B. 7 to 14 mg/dL.
  • C. 10 to 20 mg/dL.
  • D. 20 to 30 mg/dL.
Correct Answer: C

Rationale: The correct answer is C (10 to 20 mg/dL). In conditions where the serum creatinine level is elevated (7 mg/dL in this case), the BUN level is expected to also be elevated due to impaired kidney function. BUN levels are typically around 10-20 mg/dL, so this range is the most appropriate given the elevated creatinine level.

Choice A (1 to 2 mg/dL) is too low and would not be expected with a creatinine level of 7 mg/dL. Choice B (7 to 14 mg/dL) is a bit low for such a high creatinine level. Choice D (20 to 30 mg/dL) is too high as it exceeds the typical range for BUN levels. Therefore, choice C is the most appropriate range based on the given information.
