Presumptive Signs of Pregnancy ( 7 ) - ANSWER "changes that might make a woman think
shes pregnant"
-amenorrhea
-breast fullness/tenderness
-skin changes
-nausea/vomiting
-urinary frequency
-fatigue
-enlarged abdomen (12-20w) and precieved fetal movment
Probable Signs of Pregnancy ( 4 ) - ANSWER "highly suggestive of the diagnosis of
pregnancy (but don't differentiate between ectopic and intrauterine)
-uterine enlargement
-softening of uterine isthmus HEGAR SIGN
-vaginal and cervical cyanosis CHADWICK SIGN
-pregnancy tests:
~urine (pos as early as 5 days)
~radioimmunoassay for serum testing for hCG (accurate 2-3days after implantation for a
max of 60-70 days)
Positive Diagnostic Signs of Pregnancy (3) - ANSWER -fetal heart tones (7 weeks with
doppler, 18-20 weeks with nonelectronic fetoscope)
-fetal movements/"quickening" (16-18 weeks felt by pt)
-ultrasound (5-6w intrauterine gest' sac but fetal pole with movement and cardiac activity 6-
8w)
1
, 1st tri: fetal age can be estimated by CROWN to RUMP length early on and number of
fetuses
after 12-14w fetal bio-metric measurements (biparietal diameter adn femur length with be
used to do gest age accurately)
2nd trimester-fetal anatomy, placental location, amniotic fluid can be measured
EDD - ANSWER EDD: LMP plus 280 days (or 40weeks)
Neagele's Rule - ANSWER LMP + 7 days - 3 months
vaginal pH - ANSWER under normal pregnancy hormones the vaginal pH is slightly
increased (normal is 3.8-4.5)
morphologic cervical changes (ridges, hood, or collar) OR vaginal adenosis may indicate DES
exposure in utero...this makes them at higher risk for what? - ANSWER preterm labor
Uterus during pregnancy (size) - ANSWER will not change in size/consistency until 5-6
weeks
8 weeks: twice normal size
10 weeks: three times normal size
12 weeks: four times normal size, palpable at this time
McDonald measurement: height of fundal curvature to pubic symphysis
Routine Prenatal labs for first visit - ANSWER blood count
ABO blood typing and Rh factor
red blood cell antibody screen
