What action should a nurse take when a newborn's blood glucose level is reported as 40mg/dL?

When a newborn's blood glucose level is reported as 40 mg/dL, it indicates a potentially critical situation requiring immediate attention. A blood glucose level below the normal range for newborns can lead to serious complications, including seizures or long-term neurological damage if not addressed promptly. Therefore, contacting the nurse-midwife or healthcare provider (HCP) is the appropriate action to ensure that the newborn receives timely intervention and treatment to stabilize their blood glucose levels.

This action allows for further evaluation and potential treatment, which may include administration of intravenous glucose or other interventions based on clinical guidelines. The urgency of addressing hypoglycemia in neonates underscores the importance of notifying a healthcare professional rather than delaying action or opting for additional tests without first seeking guidance.
