Chapter #53: Fetal Growth Assessment by Sonography
(Correctly solved)
intrauterine growth restriction correct answers decreased rate of fetal growth, fetal weight at or
below 10% for given gestational age
maternal factors for IUGR correct answers previous history of fetus with IUGR, significant
maternal hypertension, history of tobacco use, presence of uterine anomaly, significant placental
hemorrhage, placental insufficiency
IUGR vs SGA correct answers SGA describes fetus with weight below 10th percentile without
reference to cause
basic classifications of IUGR correct answers symmetric and asymmetric
symmetric IUGR correct answers result of first trimester insult such as chromosomal
abnormality or infection, results in fetus proportionately small throughout pregnancy. all
measurements will be measuring 2 weeks behind expected gestational age
asymmetric IUGR correct answers begins in late second or third trimester and usually results
from placental insufficiency. asymmetry of head to body ratio or limb ratio
clinical signs of IUGR correct answers decreased fundal height and fetal motion
key IUGR sonographic markers correct answers grade 3 placenta before 36 weeks or decreased
placental thickness
IUGR sonographer action correct answers alert physician, determine cause. carefully evaluate
placenta and fetal anatomy, assess umbilical artery doppler for increased resistance to flow
estimated fetal weight correct answers incorporate several fetal parameters (BPD, HC, AC and
FL)
EFW below 10th percentile considered correct answers to most be IUGR
biophysical profile parameters correct answers cardiac nonstress test, fetal breathing, gross body
movement, fetal tone, amniotic fluid volume
biophysical profile guidelines correct answers BPP has time limit (30 min) to observe
parameters, each variable signed a score of 2 when normal and 0 when abnormal
normal BPP score correct answers 8-10
intermediate BPP score correct answers 4-6
