Medical Surgical Glomerulonephritis and Nephrosis #2

Question

The nurse reviews the laboratory data for a client who is diagnosed with glomerulonephritis. Which finding will the nurse expect based on the client’s medical diagnosis? Select all that apply.

Answers

  1. Negative renal biopsy.
    • Rationale:

      This answer is not correct because a negative renal biopsy is not anticipated for the client who is diagnosed with glomerulonephritis. The biopsy is often positive and useful in determining treatment and prognosis for the client diagnosed with this condition.

  2. Elevated blood urea nitrogen (BUN).
    • Rationale:

      This answer is correct because an elevated BUN is expected as the client’s kidneys are not functioning properly due to the glomerulonephritis diagnosis; therefore, the nurse expects this finding.

  3. Elevated erythrocyte sedimentation rate (ESR).
    • Rationale:

      This answer is correct because an ESR measures inflammation and because glomerulonephritis is an inflammation of the kidney, the nurse anticipates this client’s ESR will be elevated.

  4. Delayed uptake and excretion of radioactive dye in renal scan.
    • Rationale:

      This answer is correct because the kidneys are responsible for filtering and flushing waste from the client’s system. When the client is diagnosed with glomerulonephritis, the kidneys are injured and unable to rid the body of wastes and extra fluid.

  5. Proteinuria.
    • Rationale:

      This answer is correct because proteinuria is a result of the kidneys leaking large amounts of protein due to the damage to the glomeruli. It causes the urine to be foamy.

Overview

Glomerulonephritis is inflammation of the tiny filters (i.e., glomeruli) in the kidneys. Glomeruli are responsible for removing excess fluid, electrolytes and waste from the bloodstream and passing them outside of the body via the urine.

Explanation

Learning Outcomes

Glomeruli are responsible for removing excess fluid, electrolytes and waste from the bloodstream and passing them outside of the body via the urine. When glomerulonephritis is diagnosed, alterations in laboratory findings are expected. These alterations include an increased BUN and ESR. Due to the poor functioning on the kidneys, the client will also experience delayed uptake and excretion of any radioactive dye that is administered for the prescribed renal scan.

Test Taking Tip

Consider the pathophysiology of glomerulonephritis to determine which options are correct for this question.
