Final answer:
In assessing a newborn with suspected Down syndrome, one would expect to find distinct physical features such as a flat facial profile and slanted eyes among others, as well as an increased risk of intellectual disability and congenital health issues.
Step-by-step explanation:
Trisomy 21, also known as Down syndrome, is characterized by an extra chromosome 21 in the individual's karyotype. As a result of this chromosome abnormality, which is more likely to occur with increasing maternal age, affected newborns often present with distinctive clinical features and health issues.
When assessing a newborn with suspected Down syndrome, a nurse or healthcare provider would expect to note physical traits such as a flat facial profile, slanted eyes, a single deep crease across the center of the palm (simian crease), and a protruding tongue. Other findings can include low muscle tone (hypotonia) at birth and excessive flexibility. Beyond the characteristic physical appearance, there are medical conditions commonly associated with this disorder including intellectual disability, congenital heart defects, vision problems, and an increased susceptibility to certain types of cancer.
Although the focus during clinical assessment is often on the challenges associated with the condition, it is essential to provide balanced information. This includes discussing the full spectrum of potential developmental outcomes and highlighting that many individuals with Down syndrome can lead fulfilling lives with appropriate support and medical care.
