Fetal Heart – Test 7
The key terms of Test 7 include, Fetal Heart.
CSTs are used to determine how the fetal heart responds to _________ _________ that temporarily decrease placental blood flow. The CST cannot be done if stimulated uterine contractions are contraindicated.
Uterine contractions
Tests to determine fetal lung maturity
A test for fetal lung maturity is recommended when non-emergency delivery is being considered before ————- weeks of gestation.
38
Swab vaginal secretions at 24 to 34 weeks; indicates loss of fetal membrane integrity; USED TO DETERMINE PTL
Fetal fibronectin
A stress test used to evaluate the ability of the fetus to tolerate the stress of labor and delivery
Contraction stress test
A procedure used to examine the vagina, uterus, fallopian tubes, and bladder.
Invasive, probe vaginally
Doesn’t require full bladder
Obese clients
Detect ectopic pregnancy, abnormalities, est. gestational age
Transvaginal ultrasound
CVS is usually performed between ——— and ———- weeks of gestation to diagnose fetal chromosomal, metabolic, or DNA abnormalities.
10, 13
Second-trimester amniocentesis for fetal genetic abnormalities is best performed between ———- and ———– weeks because the amniotic fluid is of adequate volume and contains many viable fetal cells.
15, 20
Positive
Late decelerations follow 50% or more of contractions, even if fewer than three contractions occur in 10 minutes.
Non-reassuring CST
NST, fetal breathing movements, gross fetal movements, fetal tone, amniotic fluid volume
BPP components
Blood test that ascertains info about likelihood of fetal birth defects. Includes AFP, hCG, Estriol, Inhibin-A
DOES NOT ACTUALLY DIAGNOSE DEFECT
Quad marker screening
Pregnancies complicated by hypertension or fetal growth restriction caused by placental insufficiency can be assessed using
Doppler ultrasound
CSTs are used to determine how the fetal heart responds to _________ _________ that temporarily decrease placental blood flow. The CST cannot be done if stimulated uterine contractions are contraindicated.
Uterine contractions
