A nurse is assessing a newborn who has Trisomy 21 (Down Syndrome). Which of the following are common characteristics?

Choice A rationale Low birth weight is not a common characteristic of newborns with Trisomy 21 (Down Syndrome). In fact, infants with Trisomy 21 often have birth weights within the normal range or can even be slightly above average, although growth patterns after birth may vary. Choice B rationale Newborns with Trisomy 21 (Down Syndrome) typically exhibit hypotonia, which is decreased muscle tone, rather than hypertonia. This generalized hypotonia contributes to developmental delays and can affect feeding, motor skills, and overall posture. Choice C rationale A protruding tongue is a common characteristic of newborns with Trisomy 21 (Down Syndrome). This feature is often due to a combination of hypotonia of the tongue and mouth muscles, a smaller oral cavity, and sometimes a larger tongue, contributing to feeding difficulties. Choice D rationale Simian palmar creases, also known as a single transverse palmar crease, are a common characteristic found in newborns with Trisomy 21 (Down Syndrome). This distinct crease across the palm is a dermatoglyphic anomaly associated with chromosomal abnormalities. .
