Chapter 32: Fetal Growth Restriction Flashcards
chemical substance that is the subject of analysis
analyte
abnormal chromosome number
aneuploidy
combined observation of four separate fetal biophysical variables (fetal breathing, fetal body movement, fetal tone, amniotic fluid index? obtained via ultrasound. This can be done with or without NST
Biophysical profile
Noninvasive ultrasound test that assesses blood flow velocity profiles from which indices of impedance can be obtained or flow volumes can be calculated.
Doppler velocitremy
estimated fetal weight or abdominal circumference less than the 10th percentile for gestational age
fetal growth restriction (FGR) or IUGR
low oxygen blood level
hypoxemia
without known cause
idiopathic
birth weight below 2500 g or 5 lbs 8 ox
low birth weight
incidence of a specific disease in a population for a set amount of time
morbidity
frequency of deaths in a specific population
mortality
method of assessing fetal well-being by observing fetal heart rate accelerations
nonstress test
low amniotic fluid levels
oligohydramnios
condition characterized by the discrepancy between the chromosomal makeup of the fetus and placenta
placental mosaicism
hypertension, and protein in the urine, occurring during second half of pregnancy
preeclampsia
the proportion of people who test positive for a disease who actually have the disease
sensitivity
diagnosis used to describe an infant that is smaller than expected for the gestational age
small for gestational age
having three copies of a specific chromosome
trisomy
A newborn’s _____ closely relates to risks for early death and long-term morbidity
birth weight
Stillbirth rates _____ as fetal weight increases.
decrease
premature infant
37 weeks or earlier
LBW infants are likely a result of:
fetal growth restriction
a sonographic estimated fetal weight or abdominal circumference that is less than the 10th percentile for gestational age
fetal growth restriction
newborns identifying a neonate with a birth weight less than 2500 g or 5 lbs 8 oz
small for gestational age
Growth restricted fetuses are at an increased risk of _____, ______, and ______.
intrauterine demise
neonatal morbidity
neonatal death
