What is the normal blood glucose level for a preterm infant?

The normal blood glucose level for a preterm infant is typically above 40 mg/dL. Preterm infants are at higher risk for hypoglycemia due to various factors such as immature liver function and limited glycogen stores. Blood glucose levels below 40 mg/dL can indicate hypoglycemia and may require management to prevent potential complications.

Options indicating values like 20 mg/dL or 30 mg/dL are well below the acceptable lower limit for preterm infants. It's important to maintain blood sugar levels in a safe range, as very low glucose levels can lead to significant health issues in these vulnerable populations. Therefore, a value of 40 mg/dL is recognized as the threshold that should be maintained to ensure proper metabolic functioning in these infants.
