RECENT UPDATE
When is Magnetic Resonance Imaging used? - ANSWER ✔ - To visualize
maternal or fetal structures for detailed imaging when screening tests indicate
possible abnormalities
- Detect Placenta Accreta Spectrum (Placenta implants too deeply into uterine
muscle, attaching to other organs)
What is anencephaly? - ANSWER ✔ - Neural tube defect where part or all of the
brain stem do not develop
- Usually not compatible with life
What are MRI indications? - ANSWER ✔ - Complex fetal anomalies (brain
related) and placental abnormalities
What is the purpose of an umbilical artery doppler flow? - ANSWER ✔ - When a
baby is diagnosed with intrauterine growth restriction
What is intrauterine growth restriction? What does it indicate a lack of? -
ANSWER ✔ - Baby was measured and found to be less than the 10th percentile of
what it is supposed to be
- Indicates a lack of blood flow, restricting nutrients to the baby
- Doctor may recommend delivery to allow baby to grow on the outside because it
is not getting what it needs on the inside
, How do you interpret Umbilical Artery Doppler Flow? - ANSWER ✔ - Calculate
the difference between systolic and diastolic flow
- Increased peripheral resistance decreased diastolic blood flow
What are advantages of using umbilical artery doppler flow? - ANSWER ✔ -
Assess placenta perfusion, non-invasive
What are risks of umbilical artery doppler flow? - ANSWER ✔ - No risks
What are some examples of biochemical assessment tests? - ANSWER ✔ -
Chorionic Villi Sampling
- Amniocentesis
- Percutaneous Blood Sampling
- Maternal Assays
What is Chorionic Villi Sampling? - ANSWER ✔ - A diagnostic tests done via the
aspiration of placental tissue
- Uses ultrasound transducer to aspirate a piece of the placenta
- Can be done at 10 to 13 weeks
When is chorionic villi sampling used? - ANSWER ✔ - Performed when Maternal
Assay indicates an increased risk for abnormalities (i.e. Down's Syndrome)
- Used for chromosomal, metabolic and DNA testing
- At 10-13 weeks to assess for anomalies caused by genetic disorders
- Processess in 5-7 days
What are risks for chorionic villi sampling? - ANSWER ✔ - Infection
- Spontaneous abortion
- chorioamnionitis
- rupture of membranes
- fetal limb injury or loss
What are nursing actions for chorionic villi sampling? - ANSWER ✔ - Assess
fetal well-being with Doppler twice in 30 minutes
What is amniocentesis? - ANSWER ✔ - Diagnostic test, most common
- Uses ultrasound transducer to examinin amniotic fluid
,- 15 to 18 weeks, 95% accurate
- Can be done in third trimester to examine lung function
What are indications for amniocentesis? - ANSWER ✔ - Patient is over age 35
- History of genetic disorders
- Positive screening for alpha-fetoprotein
- Suspected hemolytic disease
What are complications for amniocentesis? - ANSWER ✔ - Infection,
miscarriage, rupture of membranes, maternal/fetal hemorrhage
What is percutaneous umbilical blood sampling? - ANSWER ✔ - Diagnostic test,
abdominal ultrasound needle
- Aspirate fetal blood from where the placenta and umbilical cord meet
- Used for identifying genetic issues or fetal blood complications (i.e. anemia, Rh
incompatibility)
- Can also be used as a transfusion technique
What is a Kleihaucer-Betke teste? - ANSWER ✔ - Test to see if maternal and fetal
blood mixed
What are risks of Pecutaneous umbilical blood sampling? - ANSWER ✔ -
Infection
- Umbilical cord injury
What is Maternal serum alpha-fetoprotein? - ANSWER ✔ - Done first in prenatal
care, screening tool, so it does not mean the baby has something, just that i has an
increased risk
- A glycoprotein produced in the fetal liver, GI tract and yolk sac in early
pregnancy
- Recommended for all pregnant patients
What does an increased alpha-fetoprotein indicate? - ANSWER ✔ - Neural tube
defects
What does decreased alpha-fetoprotein indicate? - ANSWER ✔ - Down syndrome
, What are advantages of using alpha-fetoproteins? - ANSWER ✔ - Can detect 80-
85% of NTD and 90% of ABD wall defects in early pregnancy
What are risks of fetoprotein? - ANSWER ✔ - High false positive rates, increased
maternal anxiety, need for further testing that may be invasive
Which test is more reliable, MSAFP or Quad Marker Screening - ANSWER ✔
Quad Marker Screening
What is Quad marker screening? - ANSWER ✔ - Screening tool that examines:
> Alpha-fetoprotein
> Inhibin- A
> Human chorionic gonadotropin
> Estriol levels
What percentage of Down's Syndrome can be detected via quad marker screening?
- ANSWER ✔ 60-80%
What percentage of NTD can be detected via quad marker screening? - ANSWER
✔ - 85-90%
At what gestational week is quad marker screening performed? - ANSWER ✔ -
15 to 22
What is NIPT/Cell-free DNA used for? What gestational week is it used? -
ANSWER ✔ - Cell-free DNA test
- It is used for identifying fetal sex and sex-linked defects by examining X and Y
chromosomes
- Week 9-10
What is Daily Fetal Movement Count? - ANSWER ✔ - Earliest and easiest way to
monitor fetal well-being
What gestational week is daily fetal movement count used? - ANSWER ✔ - 28
Weeks
How many movements should be detected during daily fetal movement count? -
ANSWER ✔ - 10 movements in 2 hours or 4 movements in one hour
