A nurse is reviewing the BUN and creatinine levels of an older adult client who has chronic kidney disease. The nurse should expect which of the following findings?

A. BUN of 45 mg/dL and creatinine of 8 mg/dL are elevated and consistent with chronic kidney disease due to the kidneys’ reduced ability to excrete waste products. B. Creatinine of 0.3 mg/dL is below the normal range, not consistent with CKD. C. These values are within the normal range and would not indicate CKD. D. These are both normal values, not expected in a client with chronic kidney disease.
