A nurse is monitoring a 14 year old adolescent who was admitted with a severe burn injury and shock and is receiving IV fluid resuscitation therapy. Assessment findings: Temperature 36.5C, HR 122, Respirations 22, BP 108/68. The nurse should identify a decrease in which of the following findings as an indication of adequate fluid replacement?

A. Blood pressure may fluctuate but is less sensitive as an early indicator of fluid resuscitation efficacy. B. A decrease in heart rate is a sign of improved hydration status, as tachycardia is often a compensatory response to hypovolemia. C. Weight is not used as an immediate indicator for fluid resuscitation adequacy. D. Urine output should increase with adequate fluid resuscitation; a decrease in urine output would indicate worsening.
