Unformatted text preview: 1 THE NEWBORN BABY The first 4 weeks of life is known as the neonatal period. 9 An average newborn is about 20 inches long and weighs about 7 ½ (7.5) pounds 9 95% of full-term babies weigh between 5 ½ and 10 pounds and are between 18 and 22 inches long 9 Boys tend to be slightly longer and heavier than girls 9 Firstborn child is likely to weigh less at birth than later born. Size at birth is related to: ¾ Race ¾ Sex ¾ Parent’s size ¾ Mother’s nutrition ¾ Mother’s health And tends to predict relative size later in childhood In the first few days… ¡ Neonates lose as much as 10% of their body weight, primarily because of loss of fluids. ¡ They begin to gain weight again at about the 5 th day and are generally back to birthweight by the 10 th to the 14 th day. ¡ Light full term infants lose less weight than heavy infants, and firstborns lose less than later-borns. 2 ¡ Large head (one-fourth the body length in comparison to the trunk and legs) ¡ Receding chin (which makes it easier to nurse). ¡ Neonate’s head may be long and misshapen ¢ Temporary “molding” is possible because an infant’s skull bones are not yet fused; they’ll not be completely joined for 18 months. The places on the head where the bones have not yet grown together – the soft spots, are covered by a tough membrane Frontal suture Anterior fontanel Posterior fontanel 9 Since the cartilage in the baby’s nose also is malleable, the trip through the birth canal may leave the nose looking squashed for a few days. 9 Newborn babies’ skin is soft and smooth (although temporary rashes may appear on the face) 9 Many newborns have a pinkish cast – their skin is so thin that it barely covers the capillaries 3 Lanugo A white downy hair that covers the entire body of the fetus, helping the vernix caseosa stick to the skin Vernix caseosa Is a white cheese-like substance that covers the fetus and protects its skin from becoming chapped in the amniotic fluid. It will dry within the 1 st few days after the baby is born Assessing the Newborn’s Physical Condition: It is used to assess the infant’s physical condition on 5 criteria: 9 Heart rate 9 Respiratory effort 9 Reflex irritability (such as sneezing, coughing, and grimacing) 9 Muscle tone 9 Color Each of these criteria is rated from 0 to 2. Color is the least dependable of the Apgar ratings ¡ An Apgar score of 7 or better indicates that the infant is in good physical condition....
