2 - Chapter 51 - Fetal Growth Assessment by Sonography

Question 1

sum of the four quadrants of amniotic fluid

Answer 1

amniotic fluid index (AFI)

Question 2

assessment of fetus to determine fetal well-being; includes evaluation of cardiac nonstress test, fetal breathing movement, gross fetal body movements, fetal tone, and amniotic fluid volume

Answer 2

biophysical profile (BPP)

Question 3

incorporation of all fetal growth parameters (biparietal diameter, head circumference, abdominal circumference, femur and humeral length)

Answer 3

estimated fetal weight (EFW)

Question 4

decreased rate of fetal growth; may be symmetric (all growth parameters are small) or asymmetric (may be caused by placental problem; head measurements correlate with dates; body disproportionately smaller); formerly referred to as intrauterine growth retardation

Answer 4

intrauterine growth restriction (IUGR)

Question 5

fetus measures larger than dates (diabetic fetus)

Answer 5

large for gestational age (LGA)

Question 6

birth weight greater than 4000 g or above the 90th percentile for the estimated gestational age

Answer 6

macrosomia

Question 7

uses Doptone to record the fetal heart rate and its reactivity to the stress of uterine contraction

Answer 7

nonstress test (NST)

Question 8

technique of grading the placenta for maturity

Answer 8

placental grade

Question 9

fetus born later than the 42-week gestational period

Answer 9

postterm

Question 10

fetus born earlier than the normal 38- to 42-week gestational period

Answer 10

preterm

Question 11

type of Doppler used in most fetal examinations; the transducer has the ability to both send and receive Doppler signals

Answer 11

pulsed wave Doppler

Question 12

fetus measures smaller than dates

Answer 12

small for gestational age (SGA)
