What is the maximum volume of fluid that should be given to a neonate (per kilogram)?

• A. 10 ml/kg
• B. 60 ml/kg
• C. 5 ml/kg
• D. 20 ml/kg

Answer: (A)

In neonates, fluid management is done with extreme caution because their blood volume is small and their cardiac and renal systems are immature. When you need to expand volume, give small, controlled boluses of isotonic fluid to restore perfusion without overwhelming the heart or lungs. The standard maximum amount for a single bolus per kilogram is 10 mL. This amount helps improve circulation while keeping the risk of volume overload low. After delivering that bolus, reassess perfusion closely; if perfusion remains inadequate, a second 10 mL/kg bolus can be considered, but avoid pushing more than this per kilogram in one administration. Larger per-kilogram doses or larger total volumes in a short period raise the risk of pulmonary edema and heart failure in a neonate. The other options represent either too little to effectively treat shock in most cases, or amounts that exceed the safe single-bolus limit for a neonate.
