A newborn is delivered by vaginal birth at 40 weeks of gestation. Which of the following findings should the nurse report to the provider?

A. Acrocyanosis and caput succedaneum. Acrocyanosis is a normal finding in the first 24 to 48 hours as peripheral circulation adapts. Caput succedaneum represents localized edema of the scalp from pressure during labor. These findings are benign and do not require urgent provider notification. B. Positive Babinski reflex and negative Ortolani's sign. A positive Babinski reflex is a normal neurological finding in neonates until approximately 1 year of age. A negative Ortolani's sign indicates the absence of hip click or dislocation. Both findings reflect a healthy musculoskeletal and neurological status in a newborn. C. Head circumference 40cm and chest circumference 32cm. The head circumference typically ranges from 32 to 36 cm and should only be 2 cm larger than the chest. A 40 cm head circumference indicates macrocephaly or increased intracranial pressure. This significant discrepancy requires immediate clinical evaluation to rule out hydrocephalus. D. Heart rate 160/min and respirations 40/min. A neonatal heart rate of 160 beats per minute falls within the normal range of 110 to 160. Respiratory rates between 30 and 60 breaths per minute are expected for a term newborn. These vital signs indicate stable cardiorespiratory transition post-delivery.
