The nurse is caring for an infant following the surgical repair of an atrial septal defect. Which nursing interventions are appropriate for this infant? (Select All that Apply.)

A. Offer the newborn a pacifier. This can help soothe the newborn and provide comfort, as infants exposed to opioids in utero often exhibit increased need for sucking.
B. Observe the newborn in a well-lit nursery. This is not appropriate as bright lights can overstimulate and distress the newborn.
C. Maintain a low stimulation environment. This helps reduce stress and irritability in newborns undergoing withdrawal, who can be hypersensitive to stimuli.
D. Administer oral glucose for comfort. Glucose is not typically used for comfort in NAS management; comforting measures like swaddling and pacifiers are preferred.
E. Swaddle the newborn tightly. Tight swaddling can provide a sense of security and help manage symptoms of neonatal abstinence syndrome (NAS) by reducing irritability and promoting sleep.
F. Feed the infant half-strength formula. Infants with NAS usually require regular, full-strength formula to meet nutritional needs unless otherwise indicated by specific feeding issues.

Answer: C, D

A. Hypertonia
Hypertonia, or increased muscle tone, is not a common characteristic of Trisomy 21. In fact, many infants with Down's Syndrome typically exhibit hypotonia, or decreased muscle tone, which can affect their overall strength and development.

B. Large ears
While individuals with Down's Syndrome may have unique ear shapes, "large ears" are not specifically characteristic of Trisomy 21. Instead, the ears may appear small or have a different shape compared to those of typically developing children.

C. Transverse palmar creases
Transverse palmar creases, also known as simian lines, are commonly seen in individuals with Down's Syndrome. This feature is a characteristic finding that can help in identifying the condition during physical assessment.

D. Protruding tongue
A protruding tongue is a common feature in individuals with Down's Syndrome. This occurs due to hypotonia of the oral muscles, which can lead to difficulties in tongue control and positioning.

E. Low birth weight
Low birth weight is not a defining characteristic of Trisomy 21. In fact, newborns with Down's Syndrome can have varying birth weights; they are often average weight or slightly above average, although some may be below average due to other factors related to maternal health or gestational issues.
