Early sampling of the exocoelomic cavity fluid via placenta-free areas
What is a petri dish?
Round dish used to culture fetal tissue or cells
What is an amniocentesis?
Sampling of the amniotic fluid
What is an exam done through the cervix called?

What is multifetal?
More than one fetus
What is considered advanced maternal age?
Woman aged 35 years or older
What is a chorionic villus sampling?
Sampling of the chorionic villus of the placenta
What is percutaneous umbilical blood sampling?
Sampling of fetal blood via the umbilical cord
What is another name for cordocentesis?
Percutaneous umbilical blood sampling
A common clinical technique for retrieving living fetal cells/cell products from the pregnant uterus is
Amniocentesis
An ultrasound procedure that obtains fetal blood via a needle inserted into the maternal abdomen is:
Percutaneous umbilical blood sampling
Amniocentesis testing is recommended at:
14-20 weeks
Fetal blood sampling occurs at what site?
Venous cord insertion site
Vaginal coelocentesis can provide a sample of extra-amniotic fluid as early as:
6 weeks
Women whose maternal serum alpha-fetoprotein (MSAFP) screening results reveal a value below the mean levels for a given gestational age have been associated with an increased risk for:
Trisomy
The average waiting period for amniocentesis test results, prior to molecular probe use, for chromosomal abnormalities was:
7-10 days
The main purpose of multifetal pregnancy reduction is to:
Reduce the number of embryos to improve survival for the remaining ones
Hysterosonosalpingography should always be performed during the ______________ of the menstrual cycle.
Early follicular phase
What is the most common endovaginal ultrasound puncture procedure?
Oocyte retrival
Culdocentesis is performed to:
Acquire fluid posterior to the lower uterus
Ultrasound is used to guide local treatment of the drug _________ for ectopic pregnancy resolution.
Methotrexate

Color Doppler ultrasound
The gold standard procedure for establishing tubal condition is:
Laparoscopy
Prior to pelvic radiotherapy, tumor invasion of the _______________ should be searched for with transabdominal and/or transvaginal ultrasound.

Genetic counseling
Maternal age–related chromosome abnormality risk increases after the age of:
35
Hysterosonography and hysterosonosalpingography are frequently preferable to laparoscopy because:
Ultrasound procedures are less invasive and more affordable
When is chorionic villus sampling indicated?
Advanced maternal age, previous pregnancy with chromosomal abnormalities, parental chromosomal abnormalities, positive first trimester screening, and abnormal ultrasound
What are chorionic villi?
Derivatives of the early embryo and reflect genetic makeup of the fetus
At how many weeks is CVS trans cervical approach performed?
10-14 weeks gestation
What does amniocentesis look for?
Genetic testing, lung maturity, therapeutic, and isoimmunizations
