A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value is most concerning?

  • A. Serum potassium of 5.5 mEq/L
  • B. Serum creatinine of 1.5 mg/dl
  • C. Serum creatinine of 2.5 mg/dl
  • D. White blood cell count of 8,000/mm3
Correct Answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.
