A nurse assesses a 2-day-old infant with suspected FAS. Findings include growth restriction, microcephaly, flat philtrum, and poor suck reflex. Which interpretation is most appropriate?

Rationale: A. Down syndrome presents with distinct features such as upslanting palpebral fissures, hypotonia, and single palmar crease, which differ from the findings described. B. Symptoms of Fetal Alcohol Syndrome (FAS) do not resolve spontaneously; affected infants often experience long-term neurodevelopmental and growth challenges. C. Findings such as growth restriction, microcephaly, flat philtrum, and poor suck reflex are classic signs of teratogenic alcohol exposure, making FAS the most appropriate interpretation. D. These features are not part of normal newborn transition, which typically involves temporary physiological adjustments such as mild jaundice or transient tachypnea.
