A nurse is assessing a newborn's gestational age using the New Ballard Scale.
Which of the following signs would indicate prematurity?
Thin and transparent skin
Well-developed breast buds
Creases on the bottom of feet
Developed labia.
The Correct Answer is A
Thin and transparent skin is a sign of prematurity in newborns. The New Ballard Scale is a scale that estimates the gestational age of a newborn infant based on physical and neuromuscular characteristics.
The other choices are signs of maturity or postmaturity in newborns:
• Choice B: Well-developed breastbuds indicate a gestational age of 38 to 44 weeks.
• Choice C: Creases on the bottom of feet indicate a gestational age of 32 to 44 weeks.
• Choice D: Developed labia indicate a gestational age of 40 to 44 weeks.
The normal range for gestational age is 37 to 42 weeks. Premature infants are those born before 37 weeks, and postmature infants are those born after 42 weeks.
