Practice Question
A nurse is caring for a client who reports to the clinic for laboratory tests. The client has an acute injury caused by acute tubular necrosis and asks why their glomerular filtration rate keeps decreasing. Which of the following pathophysiological changes occurring in the kidney should the nurse explain as the cause of decrease?
Answer Choices:
Correct Answer:
The glomerular filtration rate decreases because there is a reduction of blood flow to the kidneys.
Rationale:
💎 In acute tubular necrosis, a reduction in renal perfusion leads to ischemic injury of tubular cells.
💎 This perfusion loss reduces glomerular filtration rate (GFR), as the kidneys prioritize autoregulation to preserve function.
💎 Early-stage ATN is often reversible if blood flow is restored.
💎 If not corrected, the renal injury worsens, leading to further decline in filtration capacity.
💎 Management involves supporting blood pressure and optimizing renal perfusion.
