Practice Question
A nurse is monitoring a client who is dehydrated. Which of the following laboratory findings should the nurse report to the provider?
Answer Choices:
Correct Answer:
BUN 25 mg/dL (10-20 mg/dL)
Rationale:
🔹 BUN is elevated in dehydration due to hemoconcentration, which causes urea nitrogen to rise.
🔹 Although the value is only slightly above normal, it indicates impaired renal perfusion or fluid deficit.
🔹 BUN is often used along with creatinine and urine specific gravity to evaluate fluid status.
🔹 This finding should be reported because it can signal pre-renal azotemia if untreated.
🔹 Prompt intervention may prevent acute kidney injury in a dehydrated client.
