1
Q

What factos affect fetal growth?

A

1) maternal nutrition
2) genetics
3) placental function
4) environment

2
Q

What are the different terms for birthweight variations?

A

1) AGA (appropriate) about 80%
2) SGA (small)
3) LGA (large)

3
Q

What are the premature birthrrates?

A

1) LBW
2) VLBW
3) ELBW

4
Q

What is an early and late insult?

A

Earl: less than 28 weeks, leads to overall growth restriction and never catch up, always smaller

Late insult: greater than 28 weeks, lag for a little bit but then catch up usually

5
Q

what is IUGR? asymmetric vs symmetric?

A

intra-uterine growth retardation

asymmetric: head and long bones are growing normally/better compared to their abdomen and internal organs
symmetric: everything growing with a poor rate

6
Q

Look up Placenta Previa

A

has something to do with placenta not rising/growing with uterus or something, causes SGA

7
Q

Characteristics of SGA newborns

A

1) head disproportionately large
2) wasted appearance of extremities
3) low subq fat
4) scaphoid abdomen (sunken appeareance)
5) wide skull sutures
6) thin umbilical cord

8
Q

If a baby has yellowy colored staining, what is it? is this a common problem with SGA newborns?

A
  • meconium staining of vernix, yes
9
Q

Problems of SGAs

A

1) perinatal asphyxia (can cause meconium staining)
2) thermoreg difficulty
3) hypoglycemia
4) polycythemia (hypercoag problems)
5) meconium aspiration
6) hyperbilirubinemia
7) birth trauma

  • remember polycethemia = lots of RBCs and trauma releases heme group causing hyperbilirubinemia, opposite of hyper is hypo + glycemia (good way to remember a lot of this stuff)
10
Q

Nursing Management of SGAs

A

1) measurements
2) BG/vitals monitoring
3) early feedings; IV dextrose 10%

no, some do but not all

14
Q

What are the risk factors for LGAs?

A

1) maternal DM or glucose intolerance
2) prior history of a macrosomic infant
3) multiparity: as mom has more and more pregnancies, babies tend to get larger
4) post-dates gestation
5) maternal obesity
6) male fetus
7) genetics

so if mom’s obese with DM having a late-term male

15

with an LGA, what should we check right away?

A

blood sugars, monitor for hypoglycemia (extra, another one::: look at Hct b/c of polycthemia)

17
