Klepper - Lecture 1 Flashcards
dx for pregnancy
amonorrhea and (+) urine pregnancy test (UPT)
any woman of childbearing age w. new onset amenorrhea should get
UPT
gs to confirm EDD (estimated due date)
US
6-12 weeks __ is measured on US
crown rump length (CRL)
13-20 weeks __ is measured on US
biparietal diameter (BPD)
other important factors when pt presents late in pregnancy (5)
first measurable serum hcg
first urine hcg
fetal heart tones
uterine size
quickening → baby movements
first measurable serum hcg
3 weeks
first measurable urine hcg
4 weeks
fetal heart tones by doppler
10 weeks
fundal height =
gestational age (GA) starting 20 weeks gestation
how do we measure GA
time elapsed since LMP
NOT calculated from time of conception
term =
40 weeks
280 days
embryo
2-10 weeks
oogenesis happens
fetus
11-40+ weeks
lung development
brain development
why is distinction btw embryo vs fetus important
for considering teratogenesis of toxin exposure
t/f: the further a pregnancy progressed, US becomes more accurate in predicting due date
F
a pt’s lmp was 11/18/19; using naegle’s rule, what was her due date
8/25/2020
toxin exposure in fetal period poses less risk of congenital malformations bc
fetal organs have already formed (for the most part)
naegele’s rule
lmp + 7 days - 3 mo + 1 year
gavida/para
g: total # of pregnancies
p = term, preterm, abortion, living
Gx = P a b c d
when does bp return to normal in pregnancy
at term → ⅓ of all cardiac output goes to uterus
early US measurement of CRL helps establish EDC w.in
5-7 days
US becomes less accurate as
pregnancy progresses
embryonic period is from
conception - 10 weeks
fetal period is
between 10 weeks and birth
gravida refers to
total # of pregnancies, including current pregnancy
physiologic changes of pregnancy include
increased: blood volume, cardiac output
decreased: peripheral vascular resistance, ventilation, GI slowing
t/f pregnancy increases risk for VTE more than birth control
