NUR 234 Exam 1 – Solid 1/4 Questions With Complete
Solutions
amniotic membranes
Two membranes that encase the fetus, amniotic fluid, and
placenta during pregnancy
chorionic membrane- the outermost fetal membrane
amniotic membrane or amnion- forms beneath the chorion,
offers support to amniotic fluid, and also produces the fluid
amniotic fluid
fluid within the amniotic sac that surrounds and protects the
fetus
fluid never becomes stagnant because it is constantly being
formed and the fetus continually swallows fluid
normal fluid at term is 800-1200 ml
Polyhydramnios: more than 2000 ml
oligohydramnios: less than 300 ml (disturbance of kidney
function in baby)
umbilical cord
a tube containing the blood vessels connecting the fetus and
placenta
made of Wharton's jelly
fetal circulation
,fetal circulation differs from extra-uterine circulation because
the fetus derives oxygen and excretes carbon dioxide not from
gas exchange in the lungs, but from exchange in the placenta
foramen ovale
connects the two atria in the fetal heart
ductus arteriosus
a blood vessel in a fetus that bypasses pulmonary circulation by
connecting the pulmonary artery directly to the ascending aorta
meconium
the greenish material that collects in the intestine of a fetus and
forms the first stools of a newborn
what is the main cause of neural tube disorders in fetuses?
lack of folic
what is one of the few substances that doesnt cross the placenta?
insulin
when can movement be seen on ultrasonography?
as early as the 11th week
quickening
fetal movement the mother can feel
starts at week 16-20
fetal urinary system
formed by the 12th week
, lanugo
fine, soft hair, especially that which covers the body and limbs
of a human fetus or newborn.
vernix caseosa
Waxy or "cheesy" white substance found coating the skin of
newborn
naegele rule
a formula used to determine the pregnancy due date by adding 7
days to the date of the first day of the last menstrual period
(LMP), then subtracting 3 months.
estimating fetal growth
as a fetus grows, the uterus expands to accommodate its size
typical fundal measurements:
over the symphysis pubis at 12 weeks
at the umbilicus at 20 weeks
at the xiphoid process at 36 weeks
mcdonald rule
Measuring uterine fundal height in cm from symphysis pubis to
the top of uterine fundus
when can we start to hear fetal heart sounds?
as early as the 10th to 11th week
fetal heart rate should be 110-160
Daily fetal movement count (kick counts)
