P _ _ _ _
# of term infants # of premature deliveries # of abortions # of living children
frequency of prenatal visits
- initial visit 6-8 weeks after LMP
- examined every 4 weeks until 32nd week
- every 2 weeks up to 36 weeks
- weekly after
fundal ht checked first when
20 wks
check fetal hrt movement when
-nml rate
10 weeks
- 120 to 160 bpm
UA for what
glucosuria, ketonuria, proteinuria
what is quickening
first awareness of fetal movement; usually occurs 18-20 weeks in primigravida; 14-18 wks in multigravada
bleeding gums, profuse salivation, increasing varicositis, heartburn, hemorrhoids, fatigue
common complaints of PG
Advanced maternal age
35 y.o
chadwicks sign
6-8 weeks after conception
bluish cervix, vagina, labia due to venous congesion secondary to increase in estrogen
hegars sign
4-12 weeks after conception
softening of the uterine isthmus allowing palpation or compression of the connection between the fundus and cervix
ultrasound can detect fetal heart activity as early as when
5-6 weeks after LMP
what can indicate increased risk of trisomy 21
abnormally low PAPP-A and abnormally high free B-hCG
nuchal scan
-when
screen for trisomy 13, 18, 21, turner syndrome
- 10-13 weeks
b hCG peaks ..
- 100,000 by 10 weeks, decreases in 2nd trimester, then levels off in 3rd trimester
- it doubles every 48 hrs during early pregnancy
- ectopic
- monitor trophoblastic disease
- screen for fetal aneuploidy
get a quantitative b hCG when (3)
CVS advantage
- diagnostic or screening
adv: can be performed in 1st trimester, results back within 48 hrs
* * diagnositc not screening
CVS disadvantages
disadv: cannot be used in AFP testing for neural tube defects; infections, miscarriages, can get limb defects < 9wks
quadruple screen
15-18 wks; estriol, AFP, inhibin A, b hCG
CVS when. results when
10-13 wks; 48 hrs
amniocentesis when; results when
15-18 wks; 7 days
high AFP; %
risk of neural tube defects; 75-85%
estriol, AFP, and inhibin A shows risk for trisomy 21
high estriol and AFP, low inhibin A
