A nurse is assessing a newborn who has Trisomy 21 (Down's Syndrome). Which of the following are common characteristics? (Select All that Apply.)
Hypertonia
Large ears
Transverse palmar creases
Protruding tongue
Low birth weight
Correct Answer : C,D
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.

Correct Answer is ["B","C","E"]
Explanation
A. Chronic fatigue. While chronic fatigue can occur in muscular dystrophy due to muscle weakness, it is not a direct side effect of corticosteroids.
B. Weight gain: Corticosteroids commonly cause weight gain due to increased appetite and fluid retention.
C. Mood changes: Mood swings and changes in behaviour are well-documented side effects of corticosteroid use.
D. Weight loss. Corticosteroids typically cause weight gain rather than weight loss.
E. Osteoporosis: Long-term use of corticosteroids can lead to decreased bone density and osteoporosis, making bone fractures more likely.
Correct Answer is D
Explanation
A. Sole creases on heels. Sole creases are a sign of maturity and are usually present in full-term infants, not preterm.
B. Ruddy skin color. This is more common in infants with polycythemia or those who are small for gestational age, not specifically linked to prematurity.
C. Flexion of all four extremities. Premature infants typically have less muscle tone and may exhibit less flexion, often appearing more limp or having extended extremities.
D. Scant amount of vernix caseosa. Premature infants typically have more vernix caseosa, which protects their delicate skin in utero. The amount decreases closer to full term, but at 31 weeks, there may still be a moderate amount.
