Which assessment finding should the nursery nurse report to the pediatric healthcare provider?

Central cyanosis, particularly when it occurs during crying, is a significant finding that requires immediate attention. It indicates a lack of adequate oxygenation in the blood that can lead to serious complications if not addressed. Unlike peripheral cyanosis, which can be a benign phenomenon often seen in colder temperatures or due to limited blood flow to the extremities, central cyanosis indicates that there are systemic issues that need to be investigated, such as cardiac or respiratory problems. Reporting this finding to the pediatric healthcare provider ensures that the newborn receives appropriate evaluation and intervention, as it may signal underlying congenital heart disease or other respiratory distress.

The other choices, while they may warrant assessment and monitoring, do not require reporting in the same urgent manner as central cyanosis. A blood glucose level of 45 mg/dl could be concerning depending on the context and the newborn’s symptoms, but without additional clinical signs of distress, it is commonly managed under certain protocols. A blood pressure of 82/45, although on the lower end for a newborn, is sometimes within the scope of acceptable variation based on the infant's age and clinical context. A non-bulging anterior fontanel is actually a normal finding and suggests that there is no increased intracranial pressure, which would be
