pregnancy and by when does it usually resolve?
Begins @ 6 weeks
Resolves between 14 - 16 weeks gestation

Herf BBB
Definition of hyperemesis gravidarum
Extreme form of pregnancy-related nausea/vomiting, characterized by:
+ Dehydration
+ Weight loss (up to 5% of pre-pregnancy weight)
+ Ketonuria
Symptoms usually begin 3-5 weeks into pregnancy and resolve by 20
weeks
Herf BBB

pronounced?
+ Portion of areolar gland visible on skin surface
+ Become more pronounced as early as 6 - 8 weeks gestation.
How early can breast begin secreting colostrum?
As early as 16 weeks gestation, but should definitely be in by 28 weeks.
,Breastfeeding PPT
What is quickening and when can it occur?
"Quickening" refers to the mother's perception of fetal movement.
Primiparidas - At 18 - 20 weeks' gestation
Multiparidas - As early as 14 weeks' gestation
Definition of chloasma
"Mask of pregnancy" or skin darkening of forehead, bridge of nose or
cheek bones.
Usually occurs after 16 weeks' gestation
Exacerbated by sunlight What
is Chadwick's sign?
Bluish discoloration of vagina and cervix. A presumptive sign of
pregnancy.
What is Hegar's sign?
Widening and softening of the body or isthmus of uterus. Occurs at 6 - 8
weeks' gestational age.
When do Braxton Hicks contractions begin to occur?
At approx. 28 weeks' gestation.
Difference between how exercise affects BH contractions vs. true labor
contractions
+ BH contractions disappear with walking or exercise
+ True labor contractions become more intense with walking or exercise
Normal fetal heart rate
110 - 160 BPM (higher in early pregnancy)
After how many weeks are fetal heart tones detectable by handheld
Doppler?
After 10 weeks' gestation
After how many weeks can the fetus be palpated through the maternal
abdominal wall?
, After 22 weeks
Sonogram detection of the following:
+ Cardiac activity
+ Limb buds
+ Finger and limb movements
+ Cardiac activity: 5-6 weeks by transvaginal sonogram
+ Limb buds: 7 - 8 weeks
+ Finger and limb movement: 9 - 10 weeks
When and how can sonogram be used to determine gestational age of
fetus?
+ WHEN: Between 6 - 13 weeks gestation
+ HOW: Measure the crown-rump length
Uses of ultrasound in pregnancy
1) Determine viability
2) Estimate gestational age
3) Screen for aneuploidy
4) Evaluate fetal anatomy
From 13 - 20 weeks, the most accurate way to assess gestational age via
ultrasound is:
Biparietal diameter of skull
Palpable location of uterine size at:
8 weeks
12 weeks
16 weeks
20 weeks
8 weeks - @ symphysis pubis
12 weeks - in abdomen
16 weeks - Halfway between symphysis pubis and umbilicus
20 weeks - @ umbilicus
At how many weeks might the fundal height begin to decrease and why?
+ At 36 weeks the fundal height can begin to decrease as the head
descends into the pelvis.
