1

sum of the four quadrants of amniotic fluid

amniotic fluid index (AFI)

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

biophysical profile (BPP)

3

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

estimated fetal weight (EFW)

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

intrauterine growth restriction (IUGR)

5

fetus measures larger than dates (diabetic fetus)

large for gestational age (LGA)

6

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

macrosomia

7

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

nonstress test (NST)

8

technique of grading the placenta for maturity

placental grade

9

fetus born later than the 42-week gestational period

postterm

10

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

preterm

11

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

pulsed wave Doppler

12

fetus measures smaller than dates

small for gestational age (SGA)
