Question 1

Screening

Answer 1

ID if someone has an abnormality or disease (BP screening, Cholesterol Screening)
-Multiple marker screening, AFP screening

Question 2

Diagnostic Testing

Answer 2

More precise to confirm and provide a “yes” or “no” about a condition
-done after screening
-Ex: amniocentesis, Chorionic Villus Testing

Question 3

Examples of Screenings

Answer 3

-Ultrasound
-Doppler flow studies
-Alpha-fetoprotein analysis (AFP): 16-18 wks; open neural defects; protein leaked into the amniotic fluid
-Marker Screening Tests: in 2nd trimester (16-18 wks); predics chromosomal abnormalities & neural def.

Question 4

gastroschisis

Answer 4

bowel that is outside of abdomen

Question 5

causes of open neural (neural tube) defects

Answer 5

anti-seizure meds; uncontrolled DM; hot tub/ sauna use (bacteria); folic acid deficiency

Question 6

Examples of NTD (neural tube defects)

Answer 6

Spina Bifida Occulta; Meningocele; Myelomeningocele

Question 7

Prenatal Diagnostic Tests

Answer 7

*Chorionic Villus Sampling (CVS): 10- 12 wks; invasive- the back of the placenta
*Amniocentesis: after 20 wks- chromosomal abnormalities (1-2 wks for results)
*Biophysical profile: BPP- type of ultrasound

Question 8

BPP (Biophysical Profile)

Answer 8

assessment of specific fetal behavioral and physiologic characteristics. These include FETAL MOVEMENT, FETAL TONE, FETAL BREATHING movement, and amniotic fluid amount/ assessment; FHR
objective: reduce stillbirths and detect hypoxia early enough to avoid perm. fetal damage

Question 9

Types of Antepartum Fetal Testing

Answer 9

*Fetal Movement Counting
*Non-stress Test
*Contraction Stress Test or Oxytocin Challenge Test

Question 10

Fetal Movement Counting

Answer 10

-done at home
-10 movements/ 1-s hrs
-active at night? active during day?

Question 11

Non-stress Test

Answer 11

Stimulates baby for a response
-reactive is 2 or more accelerations in 20 min. (15 bpm x 15 seconds)
-non reactive

Question 12

Contraction Test or Oxytocin Challenge Test

Answer 12

the goal is a negative stress test

Question 14

BPP (Biophysical Profile) Scoring and Interpretation

Answer 14

-each parameter met is a 2, not a zero. Total 10 pts possible. 8-10 normal if amniotic fluid is adequate, 6 or less suspicious and further investigation is nec. 30 min are allotted for testing
