Question

In newborn gestational age assessment, which of the following areas is considered when assigning points, with a range from -1 to -2 for extreme immaturity and as high as 4 or 5 for postmaturity?

A) Lanugo coverage on the body

B) Presence of plantar creases on the anterior two thirds of the sole

C) Length of eyelashes and eyebrow hair

D) Thickness of fingernails

Answer 1

In newborn gestational age assessment, points are assigned based on the presence of plantar creases on the anterior two-thirds of the sole. This, along with other physical features like lanugo and fingernail thickness, helps in determining the maturity of the newborn.

Step-by-step explanation:

In newborn gestational age assessment, the area considered when assigning points, with a range from -1 to -2 for extreme immaturity and as high as 4 or 5 for postmaturity, is B) Presence of plantar creases on the anterior two-thirds of the sole. These creases develop at specific times during fetal growth and can provide a visual clue about the maturity of a newborn. In addition, the presence of lanugo, the thickness of fingernails, and the overall body proportions, including the size of the head relative to the body, can provide information about the neonate's developmental stage.

For example, a fully mature newborn would typically have plantar creases that cover the entirety of the soles of their feet. Lanugo is usually shed before birth, and fingernails will have grown to the tips of the fingers. In contrast, a premature newborn may still exhibit lanugo and less developed plantar creases, and their nails might not fully cover the nail bed.
