OB - Enhancement Notes Flashcards
ESTROGEN
- responsible for maturation of ovum
- increases quantity and pH of the cervical mucus
- inhibits secretion of FSH
PROGESTERONE
- increases basal body temperature
- inhibits secretion of LH
Placenta functions
- Passing nutrients from the mother’s blood to the fetus
- excreting wastes from fetal metabolism into the maternal
blood - transmission of oxygen from the maternal to the fetal
circulation - production of hormones required for the sustenance of
pregnancy
Placenta is complete at
12 weeks
takes charge of nutrients while placenta is not yet formed
Corpus luteum
First fetal movement
- Primi: 5 months
- Multi: 4-5 months
Position to check fetal kicks:
left side-lying to prevent compression of vena cava
Weight gain in pregnancy
1st tri: 1 lb per month
2nd tri: 1 lb per week
3rd tri: 1 lb per week
Average weight: 25-35 lbs
Normal changes in 20th week of pregnancy
- pigment changes of skin
Visual disturbances in pregnancy is a sign of
Hypertension = PIH, eclampsia
Non-stress test
measuring movement of baby; increase of HR in relation to movement; normal increase HR of 15bpm ; no oxytocin
Stress test
stimulate uterine contraction; with oxytocin then measure HR
VEAL CHOP MINE
V – Variable decelerations
Sudden drops in the baby’s heart rate.
E – Early decelerations
The baby’s heart rate slows down in sync with contractions.
A – Accelerations
The baby’s heart rate goes up briefly.
L – Late decelerations
The baby’s heart rate slows down after a contraction ends.
CHOP (Causes of FHR Patterns)
C – Cord compression
The umbilical cord is squeezed, reducing blood flow to the baby.
H – Head compression
The baby’s head is pressed, usually during labor (normal response).
O – Okay (or Oxygenation)
Accelerations mean the baby is getting enough oxygen.
P – Placental insufficiency
The placenta isn’t delivering enough oxygen to the baby.
MINE (Actions to Take)
M – Move the mother
Change position to relieve cord pressure.
I – Inspect (or identify labor progress)
Check if the baby’s head is descending.
N – No action needed
Accelerations are normal and healthy.
E – Execute interventions
Provide oxygen, fluids, or prepare for delivery if necessary.
stops labor
Tocolytic
True Labor
cervix is dilated and 90% effaced
Criteria to allow mother to walk during labor
- fetal station
Administering RhoGAM
1st Pregnancy: 28 weeks; within 72 hrs after delivery
Abruptio Placenta
- Separation of Placenta
- PAINFUL Bleeding
Causes of Abruptio Placenta
- History of AP
- PROM
- Trauma
- Hypertension
- Anything that causes vasoconstriction
Schultze AP
- central separation; bleeding in the uterus
Duncan AP
- marginal separation; bleeding outside the uterus
Placenta Previa
- can be diagnosed as early as 2nd trimester (16-20wks)
- PAINLESS Bleeding
Common Site in Ectopic Pregnancy
Ampullar
Most Fatal: Interstitial (Inside the uterus but within the walls of the uterus)
What to expect in laboratory in ectopic pregnancy
- Low hcg, low progesterone
