The following newborns are three hours old and are sleeping. The registered nurse should notify the provider about which newborn?

Choice A rationale A newborn's heart rate typically ranges from 120 to 160 beats/minute. A heart rate of 154 beats/minute falls within this normal physiological range, indicating adequate cardiac function and sympathetic nervous system regulation. This rate efficiently delivers oxygenated blood to developing tissues, supporting the high metabolic demands of a neonate. Choice B rationale A newborn's normal respiratory rate is typically 30 to 60 breaths/minute. A rate of 72 breaths/minute indicates tachypnea, which can signify respiratory distress, infection, or other underlying pulmonary or systemic issues. Persistent tachypnea warrants further investigation to prevent potential hypoxemia or respiratory failure. Choice C rationale A capillary hemangioma is a benign proliferation of endothelial cells forming a vascular lesion. These "strawberry marks" are common in newborns, often appearing within the first few weeks of life and typically resolving spontaneously. Their presence does not usually indicate an acute medical emergency or require immediate provider notification. Choice D rationale Whitish, hardened nodules on the gums of a newborn are commonly known as Epstein pearls or Bohn's nodules. These are benign, keratin-filled cysts that are normal developmental findings. They are remnants of the dental lamina and typically disappear within a few weeks or months without intervention, causing no discomfort to the infant.
