medium · NCLEX-RN Reduction of Risk Potential
A nurse reviews the following laboratory results for a client with suspected dehydration: Blood Urea Nitrogen (BUN) 36 mg/dL (Reference: 7-20 mg/dL) and Serum Creatinine 1.2 mg/dL (Reference: 0.6-1.3 mg/dL).
What is the most accurate interpretation of this laboratory trend?
- These values are expected findings for an aging client and do not require follow-up.
- The elevated BUN is likely due to a high-protein diet rather than a fluid balance issue.
- The client has developed acute intrinsic renal failure requiring immediate dialysis.
- The BUN-to-creatinine ratio is 30:1, suggesting a pre-renal cause such as volume depletion.
