newborn. b.
Sebaceous glands are overproductive in the
newborn. c.
The newborns skin is more permeable than that of the
adult. d.
The amount of vernix caseosa dramatically rises in the newborn. - CORRECT ANSWER -ANS: C
The newborns skin is thin, smooth, and elastic and is relatively more permeable than that of the
adult; consequently, the infant is at greater risk for fluid loss. The subcutaneous layer in the
infant is inefficient, not thick, and the sebaceous glands are present but decrease in size and
production. Vernix caseosa is not produced after birth.
