What is the placenta?
"Pancake" - It is the tissue attached to the uterine wall that nourishes the fetus through
the umbilical cord.
What does the umbilical cord consist of?
2 arteries and one vein
What is the amniotic membrane?
-Underneath the chorionic membrane
-This membrane has no nerve supply, so when it ruptures the mother nor fetus feel any
pain
-Produces amniotic fluid
Describe the amniotic fluid
The liquid surrounding the fetus in utero. It absorbs shocks, permits fetal movement,
and prevents heat loss.
Volume of amniotic fluid changes constantly (10wks: 30cc; Term: 1000-2000 cc)
Fetus swallow fluid
, Fluid flows into and out of the fetal lungs
Fetus urinates (adds to amniotic volume)
What is hydramnios?
Excessive amniotic fluid (>2000mL fluid or >8oz fluid pocket on US) that occurs when
fetus is not swallowing the fluid.
Why can hydramnios occur in women with gestational diabetes?
Hyperglycemia can cause excessive fluid shifts into the amniotic space
What is oligohydramnios?
Too little amniotic fluid (<300mL or <1cm fluid pocket on US)
-Caused by impaired fetal kidney fxn
What is the normal FHR?
110-160 bpm
What is surfactant and what does it do?
A phospholipid substance that is formed and excreted by fetal lungs.
-Prevents lungs from sticking together
Describe Naegele's Rule for estimated due date:
1st day of LMP - 3 months + 7 days
(EX: if LMP was May 14, subtract 3 months = February 14 + 7 days = February 21)
[estimated due date is +/- 2 weeks)
Calculate Naegele's Rule for a client whose first day of their LMP was May 15.
February 22
Describe McDonald's Rule
