Prenatal ASSESSING & genetic testing

What is a screening?

A test used to detect something

What is a diagnostic test

A test used to DIAGNOSE

What is the name of the prenatal Assessment where you COUNT the kicks of your baby?

What is a BAD result?

What is a Good result?

counting fetal kicks within 1 hour

• BAD = less than 10 in 2 hours

• GOOD = more than 10 in 2 hours

What is a NON-stress test? What two things are you looking for?

You look at the Fetal HR monitor and r reactive or Non-reactive

What is the difference between NON-reactive and a REACTIVE showing on a non-stress test?

REACTIVE = there are 2 acceleration and moderate variability

NON-REACTIVE = there are NO accelerations & NO moderate

What is a biophysical profile? Is it a screening or diagnostic? what FOUR things are you looking for?

ultrasound of baby; screening

tone

movement

amount of amniotic fluid,

breathing

How is a biophysical profile scored? what gets an added 10 points? (if present)

0-2 pts and if there is a reactive on fetal HR

What is a contraction stress test? How does it work?

Looking at fetal Hr during contractions

what is a BAD contraction stress result?

What is a GOOD contraction test result?

BAD - late decel

Good - NO Decels

Genetic testing, tests for which types of chromosomes?

21, 18 & 13

an extra chromosome on 21 means what?

DOWN syndrome

What does a “soft marker” mean in a screening?

it COULD be there but needs a diagnostic test to confirm

Dominant genetic disorder, means only ________ gene is needed to have the genetic disorder.

ONE

Recessive menas ________ genes are needed to have the genetic disorder

TWO

list the FOUR genetic SCREENING tests?

Cell-free DNA

Fetal Translucency

Quad screenings

Biophysical profile

How is a cell-free DNA test completed?

Take the mom’s blood and test i

How is a fetal Nuchal translucency test completed? Is this a screening or diagnostic test?

How many weeks gestation is this completed?

An ultrasound of baby. measures the amount of amniotic fluid in neck; Screening

How is a Quad screening completed? What are you specifically testing for?

h

Take mom’s blood and test it for neural tube defects

How is the CVS (chronic) Villus Sampling completed? Is this diagnostic or Screening?

Take a sample of placental DNA and test it

Say, mom tests neg for Rh factor, what must you add to a CVS or Aminocentesis?

RHOGAM

When is the ONLY instance a diagnostic test is used?

When a screening test is positive

How is an aminocentesis done?

Take a sample of amniotic fluid and test it

Is an amniocentesis a SCREENING or DIAGNOSTIC test?

Diagnostic

What does free-cell DNA test for? What do these indicate?

Hint: answer has to do w/ DNA

Trisonomal 13, 21, & 18 (genetic disorders)

What does a quad screening test for? If the mom is not enough gestation, what is an alternative screening test they can do?

Neural tube defects: Fetal ultrasound

What are TWO major complications from diagnostic tests (CVS & amniocentesis) to look out for?

Miscarriage and infection

What may happened first to indicate the NEED for a Biophysical profile of a baby?

(hint: THIS is why 10 points are added to this based on reactive non-stress test)

a non-reactive, non-stress test

What is something. Else you can find out if you have an aminiocentisis?

The Gender of baby

Almond shape eyes With UPWARD, transverse PALMAR crease, & protruding tonnage are all signs of what genetic condition?

Down syndrome

If you perform a non-stress test and everything is normal apart from no fetal movement. Why would this be? What can you do to intervene? And why?

Because the baby Is sleeping; Give mom some food because increase your mom’s blood sugar could wake baby up
