Correct Answer is C
Explanation
Choice A rationale
A BUN level of 45 mg/dL is elevated, indicating impaired kidney function. However, a serum creatinine level of 1.0 mg/dL is within the normal range, which is not consistent with chronic kidney disease.
Choice B rationale
A BUN level of 11 mg/dL is within the normal range, but a serum creatinine level of 10 mg/dL is significantly elevated, indicating severe kidney dysfunction. This combination is not typical for chronic kidney disease.
Choice C rationale
A BUN level of 35 mg/dL and a serum creatinine level of 8 mg/dL are both elevated, indicating impaired kidney function. These values are consistent with chronic kidney disease.
Choice D rationale
A BUN level of 10 mg/dL and a serum creatinine level of 0.3 mg/dL are both within the normal range, which is not consistent with chronic kidney disease.
