A 10-year-old burn patient with 30% TBSA shows the following changes in since the start of your shift three hours ago: Parameter Start of shift Current Heart rate (bpm) 105 145 Blood pressure (mm Hg) 110/70 88/54 Urine output 1.2 mL/kg/hr 0.3 mL/kg/hr Which interpretation is most accurate?

A. The child is developing burn shock due to inadequate fluid resuscitation: The rising heart rate, falling blood pressure, and markedly decreased urine output indicate hypovolemia. These findings are consistent with burn shock, which results from massive fluid shifts and capillary leakage in major burns. B. The child is showing signs of fluid overload from excessive IV fluid administration: Fluid overload presents with hypertension, bounding pulses, and pulmonary edema. The child instead shows hypotension and poor urine output, which indicate fluid deficit. C. The child's low urine output is expected in the first 24 hours after burn: Oliguria is not expected if fluid resuscitation is adequate. Persistently low urine output despite fluid replacement signals hypoperfusion and inadequate circulation, requiring urgent intervention. D. The child is experiencing adequate fluid resuscitation: Adequate resuscitation would be reflected by stable vital signs and urine output around 1 mL/kg/hr. The worsening tachycardia, hypotension, and oliguria show that fluid needs are not being met.
