Final answer:
The nurse should report the finding of substernal retractions to the provider, as it may indicate a potential breathing problem or lung issue. Acrocyanosis is a common finding in newborns and usually resolves on its own. Overlapping suture lines and a head circumference of 33 cm are within the expected range for a newborn and do not require immediate medical attention.
Step-by-step explanation:
The nurse should report the finding of substernal retractions to the provider. Substernal retractions are a sign of respiratory distress in newborns and may indicate a potential breathing problem or lung issue. The nurse should notify the provider so appropriate interventions can be taken to ensure the newborn's well-being.
Acrocyanosis, which is cyanosis or bluish discoloration of the extremities, is a common finding in newborns and usually resolves on its own within a few hours or days. It is not considered a cause for immediate concern.
Overlapping suture lines, where the bones of the skull meet, can also be a normal finding in newborns and does not typically require medical intervention.
A head circumference of 33 cm (13 in) is within the expected range for a newborn. The nurse should continue to monitor the head circumference as part of the newborn's growth assessment.
