A nurse is reviewing the laboratory reports for a client who has chronic kidney disease Which of the following laboratory reports should the nurse expect to find?

A. BUN 11 mg/dL, serum creatinine 0.8 mg/dL: These values are normal (BUN: 7-20 mg/dL, creatinine: 0.6-1.2 mg/dL), which are not expected in chronic kidney disease (CKD). B. BUN 15 mg/dL, serum creatinine 1.0 mg/dL: Also within normal limits. C. BUN 10 mg/dL, serum creatinine 0.6 mg/dL : These values suggest normal kidney function, not CKD. D. BUN 25 mg/dL, serum creatinine 2.3 mg/dL : Both elevated BUN and creatinine indicate impaired kidney function, which is expected in CKD.
