Transvaginal Ultrasound can be used to measure crown rump length of the fetus in first
trimester which helps determine approximate gestational age +/- one ________ ✔Correct
Answer-Week
________ is performed by inserting a catheter into the uterus to obtain placental villi for
testing . The tissue may also be obtained through abdominal wall if needed to safely reach the
placenta ✔Correct Answer-CVS
CVS can be used to do chromosomal, DNA, and enzyme analysis on placental tissue and is
usually performed at _________weeks. One of the earliest tests to reassure parents provide
information needed to decide whether to continue the pregnancy ✔Correct Answer-10-13
Uterine fundus can be palpated above the symphysis pubis by _______ weeks ✔Correct
Answer-10-12
From gestation 16-36 weeks, fundal height can be used to estimate weeks of gestation. By week
______, fundus is usually at umbilicus. ✔Correct Answer-20
During first trimester, the procedure most commonly used to confirm fetal viability is
______________ ultrasound ✔Correct Answer-Transvaginal
SGA infants are those whose weight places them below the ____th percentile for gesatational
age ✔Correct Answer-10
When fetus does not fulfill his/her growth potential for any reason, diagnosis is _________. This
is associated with oligohydramnios and PreE ✔Correct Answer-IUGR
___________ IUGR babies have both head and body that are small. ✔Correct Answer-
Symmetric
Symmetric IUGR tends to occur _________ in pregnancy and is commonly caused by
chromosomal abnormalities and infections ✔Correct Answer-Early
, ____________ IUGR babies have small body, but head is normal size. ✔Correct Answer-
Asymmetric
Asymmetric IUGR occurs _________ in pregnancy and is commonly caused by placental
insufficiency and PreE ✔Correct Answer-Late
LGA babies are those whose weight places them above the ______th percentile for gestational
age ✔Correct Answer-90
The main pathological cause for LGA is maternal ______ ✔Correct Answer-Diabetes
Infants exposed to elevated levels of glucose produce elevated amounts of _________ which
has an anabolic effect on the growing fetus leading to macrosomia ✔Correct Answer-Insulin
LGA babies are most likely to develop hypoglycemia _______ hours after birth ✔Correct
Answer-1-2
_____ babies are more at risk for hypoglycemia, hyperbilirubinemia, hypocalcemia,
hypomagnesemia, hyperviscocity d/t polycythemia, lethargy, RDS, and birth defects ✔Correct
Answer-LGA
_________is the insertion of a 20-22 gauge spinal needle through abdominal wall to obtain
amniotic fluid for analysis. Fluid is cultured and genetic studies can be done. Biochemical
disorders, CNS anomalies, ventral wall defects and other disorders can be diagnosed.
✔Correct Answer-Amniocentesis
If an amniocentesis is done before ______ weeks, the sample can only contain 1 mL per week of
gestation. Early amniocentesis is much more difficult and carries higher risk of fetal death, ROM,
and club feet ✔Correct Answer-14
Most amniocentesis procedures are done at _________ gestation ✔Correct Answer-14-20
_________ is AKA cordocentesis. It is a procedure to obtain fetal blood cells in order to assess
RBC and platelet status. A 22 gauge spinal needle is inserted into umbilical vein at or near place
where it joins placenta while using ultrasound. May be done to verify results from other tests
✔Correct Answer-PUBS
After PUBS, fetal blood cells are used for genetic analysis with karyotyping with results available
within ________ hours. Immunological, hematological, and metabolic studies can be done. Fetal
acid-base status can be determined. ✔Correct Answer-24-48
This vessel carries oxygenated blood from the placenta to the baby ✔Correct Answer-
Umbilical vein
