A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client's urine output is 25 ml/hour. What is the most likely cause?

  • A. This is a normal finding after surgery.
  • B. Oliguria signals tubular necrosis related to hypoperfusion.
  • C. Oliguria signals dehydration and fluid loss.
  • D. Urine output of 25 ml/hour is an expected finding after splenectomy.
Correct Answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.
