What is considered a critical early intervention for hypoglycemic infants?

Administering D10 IV fluids is the correct choice for a critical early intervention in hypoglycemic infants because it directly addresses the immediate need to raise blood glucose levels. Infants with hypoglycemia can exhibit symptoms like irritability, lethargy, or seizures, which can escalate if not treated promptly. D10, or dextrose 10%, is a concentrated carbohydrate solution that can rapidly increase blood sugar levels when administered intravenously, making it an effective and fast-acting treatment option.

Oral glucose can be less effective in cases where the infant is unable to swallow or is not alert enough to take anything by mouth due to their condition. High-dose insulin is inappropriate as insulin decreases blood glucose levels rather than raising them. Conducting a blood transfusion is not relevant to treating hypoglycemia, as it does not address the issue of low blood sugar and is reserved for conditions like anemia or significant blood loss. Therefore, the use of D10 IV fluids serves as a specific and critical early step in the management of hypoglycemic infants.
