Which finding best indicates improvement after fluid boluses?

• A. Improved urine output
• B. Decreased heart rate
• C. Worsened mental status
• D. Persistent tachypnea

Answer: (A)

Assessing response to a fluid bolus in a child centers on perfusion; the clearest sign that perfusion has improved is an increase in urine output. When kidneys receive better blood flow, they filter more and produce urine, so a rise in urine output directly reflects improved systemic circulation and end-organ perfusion. A practical goal is roughly 0.5 mL/kg/hour in many pediatric patients after resuscitation. Other signs like heart rate, mental status, or breathing rate can be influenced by many factors. Heart rate may decrease for reasons beyond fluid response; mental status can improve or be affected by sedation, pain, or metabolic issues; tachypnea can persist due to lung pathology or acidosis. Thus, the best indicator that a fluid bolus has improved perfusion is an actual increase in urine output.
