Answers

1
contraction Stress Test
kidney-stimulated contraction test or tocolytic stimulants
non-invasive
at least 3 contractions in 10 min. lasting 35 seconds-CST
standardized
2
Amniocentesis
empty bladder after 20 weeks
full bladder in 3rd trimester
10 weeks; sterile needle aspiration into amniotic fluid
non-invasive
3
Maternal Vaginal Secretions
pap smear cystitis
Group B Strept
group A street
Lead paint
4
Non-Stress Test
reports fetal heart rate accelerations up 15 beats/15 sec. 2x in 20 minutes
1st trimester procedure for GDM
FHR decelerations
nonreactive NST best results
5
Percutaneous Umbilical Blood Sampling
clean procedure
preterm labor, umbilical cord laceration risk
no complications
Maternal blood sampling
6
Quad Marker
urine sample at 16-18 weeks
HCG, AFP, Estriol ,Inhibin A screening
Multiple Permanent Marker
blood sample at 10 weeks
7
Multiple Marker Results
Noninvasive lab
High AFP: Downs Risk
Low AFP : cardiac defect
High AFP: NEURO Tube Defect
8
Maternal Serum Blood Tests
screenings
No necessary
diagnostics
only 2 tests
9
Chorionic Villus Sampling(CVS)
empty bladder
low risk for spontaneous abortion or limb loss if < 9 weeks
Full bowel
10-13 weeks diagnostics for fetal abnormalities
10
Biophysical Profile
Abdominal Ultrasound to visualize fetus physically and physiologically
follow-up negative contraction test
vaginal US
follow-up reactive stress test
11
What is the purpose of an standard ultrasound?
confirm pulmonary blood flow
diagnose chromosomal defects
Locate a figure of a fetus or find placental location
assess cranial abnormalities
12
Purpose of doppler ultrasound
assess fetal position
assess fundal height
invasive diagnostic
determine maternal-fetal blood flow
13
Maternal Serum AFP
High AFP results-Downs
screens for Nerol Tube Defect at 16-18 weeks
low results AFP -NTD
urine sample
14
Clean catch urine
liver disease
infection
protein and glucose
