NUR 106 Module B Study Set with
Questions and Correct Answers
Alpha-fetoprotein (AFP) ✅plasma protein produced by the fetus
Amniocentesis ✅needle puncture of the amniotic sac to withdraw amniotic fluid for
analysis
-Can diagnose chromosomal abnormalities
-rh compatibility
-Lung function/maturity
Contraction Stress Test ✅a stress test used to evaluate the ability of the fetus to
tolerate the stress of labor and delivery
L/S ratio (lecithin/sphingomyelin) ✅- Used to evaluate lung maturity
- LS stabilizes neonatal alveoli to prevent collapse on expiration
- Lecithin in amniotic fluid is ↓ than Sphingomyelin until 26wks
- At 30-32wks the two lipids are equal
- At 35wks lecithin levels rise sharply
- Normal value is 2:1 or ↑
- If mom has DM the ratio should be 3.5:1 or ↑
Neural Tube Defect ✅malformations of the brain, spinal cord, or both during embryonic
development that often results in lifelong disability or death
Nonstress Test ✅A method for evaluating fetal status during the antepartum period by
observing the response of the fetal heart rate to fetal movement.
Abortion ✅termination of pregnancy before the embryo or fetus is capable of surviving
outside the uterus
-Intentional or Circumstantial

What do low levels of AFP indicate? ✅Down syndrome or Molar Pregnancies
What do High Levels of AFP indicate> ✅-Neural Tube Defects
-Ancephaly
-Spina bifida
Multiple Marker Screening ✅Analysis of maternal serum for abnormal levels of alpha-
fetoprotein, human chorionic gonadotropin, and estriols that may predict chromosomal
abnormalities of the fetus
-Multiple types of screens
-Most common run is Quad Screen
What is ALWAYS used with amniocentesis ✅Ultrasound guidance
Good Fetal Lung Ratio ✅2:1
What are the ways a CST can be induced? ✅-Nipple stimulation
-Pitosin
Variable Decelerations ✅HR up or down with contractions
-Indicates cord compression
Early Decelerations ✅HR decreases right before uterine contraction
-Indicator of head compression
-Good sign if nearing end of labor
Late Decelerations ✅HR decelerates after contraction
-Medical Emergency
-Indicated Utero-Placental Insufficiency
