Final answer:
A nurse assessing a newborn with specific facial features may suspect the presence of Fetal Alcohol Syndrome, which is caused by maternal alcohol consumption during pregnancy. The nurse would look for evidence of alcohol use in the mother's history to confirm this and to provide the necessary care and support.
Step-by-step explanation:
When a nurse observes a newborn with a low nasal bridge, short upturned nose, flattened midface, and a long philtrum with a narrow upper lip, these physical features suggest the infant may be affected by a condition known as Fetal Alcohol Syndrome (FAS). FAS is part of a spectrum of disorders called Fetal Alcohol Spectrum Disorders (FASDs), which are caused by the mother's consumption of alcohol during pregnancy. These conditions can lead to a variety of developmental, cognitive, and behavioral problems, as well as the distinct physical characteristics noted during assessment.
The nurse would therefore suspect to find in the mother's history evidence of alcohol use or abuse during pregnancy. This information is crucial for developing an appropriate care plan for the child and may involve coordinating with child protective services and providing resources for both the infant and the mother. It is important for the well-being of both the mother and child that such concerns are handled with sensitivity and confidentiality.
