Postoperative client with fluid volume deficit. Which change indicates successful treatment?

  • A. Decrease in heart rate
  • B. Increase in blood pressure
  • C. Decrease in respiratory rate
  • D. Increase in urine output
Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.
