Final answer:
If a nurse identifies the absence of the red reflex in the eyes during a newborn assessment, the nurse should notify the practitioner.
Step-by-step explanation:
If a nurse identifies the absence of the red reflex in the eyes during a newborn assessment, the nurse should notify the practitioner. The red reflex is a normal response to light that indicates a clear pathway for light to reach the retina. Absence of the red reflex could be a sign of an underlying issue with the eyes that requires further evaluation and intervention.
