FHR Reactivity – Test 8
The key terms of Test 8 include, FHR Reactivity.
FHR reactivity with__________ is a reassuring sign associated with adequate fetal oxygenation and intact neural pathway from the fetal brain to the heart.
Accelerations
The NST is noninvasive, painless, and believed to be without risk to mother or fetus. For these reasons, it is the primary means of fetal surveillance in pregnancies that are at increased risk for _____________ and consequent fetal hypoxia and acidosis.
Uteroplacental insufficiency
—————— levels of MSAFP are associated with chromosomal anomalies, such as trisomy 21 (Down syndrome).
Low
Consists of a woman lightly brushing her palm across her nipple for 2 min, which causes the pituitary gland to release endogenous oxytocin, and then stopping the nipple stimulation when a contraction begins. The same process is repeated after a 5-min rest period.
Nipple-stimulated contraction test
A CST, or ———- ———– ———– (OCT) may be done if NST findings are nonreactive, although the next step is usually an ultrasound examination for a BPP.
Oxytocin challenge test (OCT)
Pregnant women should be offered MSAFP screening, ideally between ———— and ———— weeks of gestation
16, 18
A technique of prenatal diagnosis in which amniotic fluid, obtained by aspiration from a needle inserted into the uterus, is analyzed to detect certain genetic and congenital defects in the fetus.
Amniocentesis
High frequency sound waves to visualize internal organs and tissues by producing real-time 3D image of the fetus and maternal structures. Early diagnosis of complications, earlier interventions
Ultrasound
CVS can be performed as early as ———– weeks of gestation to provide parents with information about many chromosomal defects in the first trimester of pregnancy.
10
The NST identifies whether an increase in the ———- occurs when the fetus moves, indicating adequate ————-
FHR, oxygenation
The AFP concentration ——————- with advancing gestational age of the fetus
Increases
Pregnant women should be offered MSAFP screening, ideally between ———— and ———— weeks of gestation
