On day one of birth for a term infant, what is a normal blood glucose level?

A normal blood glucose level for a term infant on the day of birth is indeed 40 to 60 mg/dL (2.2 to 3.3 mmol/L). This range is essential to monitor as hypoglycemia can have serious implications for neonates. Newborns, particularly those who are term, typically maintain their blood glucose levels within this range without significant intervention.

Blood glucose levels lower than this could indicate a risk of hypoglycemia, which may require additional monitoring and potential intervention. Conversely, higher levels may occur in conditions such as maternal diabetes but are less common in healthy, term infants.

The other ranges presented in the options fall outside the established norms for early neonates. For instance, the range of 50 to 80 mg/dL could be considered on the higher side for a newborn right after birth, while levels of 60 to 100 mg/dL and 30 to 50 mg/dL also do not align with the standard guidelines for appropriate blood glucose levels during this critical time. Understanding these values helps in assessing and managing the health of newborns effectively right at the start of life.
