Multi Gravida EDC
Date of Quickening + 5 mos + 4 days
solve for EDC - primigravida
Date of quickening + 4 mos & 20 days
Uses fundal height to determine duration of pregnancy
Mc Donalds Rule
Distance from fundus to symphysis pubis in cm is equal to the week if gestation between 20th - 31st week
mc donalds rule
aog formula using mcdonalds
FH x 8/7
measures age of gestation by determining the position of the fundus in the abdominal cavity
bartholomew’s rule of fours
normal length

trimester 3
a fetus usually moves a minimum of 2x energy 10 mins or an average if 10-12 times
SADOVSKY METHOD
within 60 mins
cardiff method
heart rate should be 120-160 bpm
fetal heart rate sounds/ rate
how many beats per minute mo taas everytime baby moves
15bpm
baseline, short term variability / flower /beat to beat
Rhythm strip testimg
measures response of the FHR to fetal movement, REACTIVE & NON
Non-stress test
0.5u min of 15-20 mins interval until 3 high wuality uterine contractions are obtained within 10 mins. used 32-44 week of contraction
stress test (ontraction stress test)
oxytocin challenge test
facikitate lroduction if milk
Nipple stimulation stress test (breast self stim)
- assess several variables
~.fetal breathing movements - fetal body movements
fetal muscle tone
placental grades
biophysical profile
non invasive and painless, done by intravaginal technique
ultrasound
widest transcerse diameter of the fetal head
8.5cn or more then fetuks will weigh
bipara (biparietal diameter, fetals head)
turbulence of blood in uc
dopper umbilical velocimetry
placentas can be graded
placental grading
complement ultrasound as a fetal assessment technique
MRI
-2.5 median of N <2.5 neural tube
requires blood sample obtained theu venipuncture
maternal serum alpha = fetoprotein
blood sample that tests 3 paraneters maternal serum for alpha pregnancym on cojugated ove it alr some
triple screening
-12wks of pregnancy
-foelocentesis, alternative
chorionic villi sampling (vs)
