Hegar's sign
6th week of pregnancy, the lower uterine segment is so soft that it can be compressed to the thinness of paper, allowing the uterine segment to be flexed against the cervix
35
Chadwick's sign
bluish, purple discoloration of the mucous membranes of the cervix/vagina; caused by increased vascularity of the pelvic organs, one of the earliest signs of pregnancy
36
Fetal outline
can be palpated by an experienced practitioner by the 2nd half of pregnancy
37
Ballottment
when a sudden tap on the cervix during vaginal examination near mid-pregnancy causes the fetus to rise in amniotic fluid and rebound to its original position
38
Braxton hicks
contractions that occur throughout pregnancy and are usually irregular and painless, most women do not notice until the 3rd trimester
39
Pregnancy tests
based on the presence of hCG in maternal urine and may be used as early as 3 days after a missed period (home kits are 97% accurate if used correctly)
40
Radioimmunoassay tests
use radioactive markers to detect antibodies against hCG in the blood or urine, done in a lab and are accurate as early as 1 week after ovulation
41
ELISA enzyme

weighs about 20 ounces, 6 inches long, the uterus is at belly button level, the fetus can yawn/suck a thumb/stretch/make faces
78
What are the fetal membranes (2)
Amnion (inner), chorion (outer)
79
Amnion
inner membrane, the developing embryo draws amnion around itself to form a fluid-filled sac, becomes the covering of the umbilical cord and covers the chorion on the fetal surface of the placenta
80
Chorion
outer membrane, becomes the covering of the fetal side of the placenta, contains major umbilical blood vessels
81
Amniotic fluid
protects the fetus and promotes development, derived from fetal urine (cause of kidney problems), fetus breaths in amniotic fluid while in utero
82
Umbilical cord veins and arteries
2 arteries that carry non-oxygenated blood to the placenta from the fetus, 1 vein that carries oxygenated blood to the fetus
83
What is involved in the 5 adaptions made during fetal circulation
umbilical vein, ductus venosus, foramen ovale, ducts arteriosus, umbilical arteries
84
What does the umbilical vein turn into
the ligamentum teres after the cord is clamped because it is functionally closed
85
Ductus venosus
Most of the blood passes through here into the inferior vena cava. There mixing with deoxygenated blood from the fetal legs and abdomen on its way to the right atrium
86
What does the ductus venosus turn into
the ligamentum venosum after the cord is clamped because it is functionally closed
87
Foramen ovale
most of the blood passes straight through the right atrium and through the foramen ovale, an opening into the left atrium. There mixing with the small amount of deoxygenated blood returning it from the fetal lungs through the pulmonary veins
88
What happens to the foramen ovale
closes at birth because there is an increased pulmonary blood flow from the left side, causing increased pressure in the left atrium
89
Ductus arteriosus
fetal lungs do not function for respiratory gas exchange, so the pathway bypasses the lungs, blood flows from the pulmonary artery to the aorta
90
What does the ductus arteriosus turn into
the ligamentum arteriosum after the cord is clamped because it is functionally closed
91
What happens to the PO2 level when the ductus arteriosus closes
increases
92
What has an important role in closing the ductus arteriosus
circulating prostaglandin E
93
What does the umbilical artery turn into
medial umbilical ligament after the cord is clamped because it is functionally closed
94
What does clamping of the umbilical cord cause
a rise in blood pressure which increases circulation and lung perfusion
95
Vena cava syndrome
when the gravid uterus rests on top of the vena cava, maternal blood flow is diminished or cut off, causing maternal hypotension and dizziness
96
Human chorionic gonadotropnin (hCG)
early pregnancy hormone that stimulates the corpus lutem to produce progesterone and estrogen to maintain pregnancy, causes a positive pregnancy test
97
Human placental lactogen (hPL)
antagonist to insulin, freeing fatty acids for energy so glucose becomes available for fetal growth
98
Estrogen
stimulates uterine and breast (duct) development, produced by the placenta after the 7th week
99
Progesterone
maintains uterine lining for implantation, relaxes all smooth muscles preventing contractions, develop breasts (lobules) for lactation, facilitates deposits of maternal fat stores for energy, inhibits oxytocin
100
Relaxin
inhibits uterine activity diminishing the strength of uterine contractions, aids in softening of the cervix, relaxes muscles and joints in the body
101
Prolactin
prepares the breasts to produce milk
102
Oxytocin
stimulates contractions of the uterus to help birth occur, helps to keep the uterus contracted to prevent hemorrhage after birth
103
First trimester discomforts of pregnancy (7)
nausea/vomiting, urinary frequency, fatigue, breast tenderness, increased vaginal discharge, nasal stuffiness and epistaxis
104
What is the cause of nausea and vomiting in the first trimester
unknown but believed to be elevated hCG/estrogen levels, decreased blood sugar
105
What is the cause of urinary frequency in the first trimester
the bladder is being squeezed by an enlarging uterus
106
What is the treatment for urinary frequency
urinate frequently, Kegel exercises
107
What is the cause of fatigue in the first trimester
effects of relaxin, hypoglycemia, anemia
108
What is the cause of breast tenderness in the first trimester
effects of estrogen and progesterone
109
What is the cause of increased vaginal discharge in the first trimester
increased production of mucus due to increased estrogen levels
110
What is the cause of nasal stuffiness and epistaxis in the first trimester
elevated estrogen levels
111
Second-trimester discomforts of pregnancy (7)
heartburn (pyrosis), constipation, hemorrhoids, varicose veins, leg cramps, ankle edema, backache
112
What is the cause of heartburn in the second trimester
diminished gastric motility, displacement of the stomach by the enlarging uterus, relaxation of the cardiac sphincter
113
What is the cause of hemorrhoids in the second trimester
vascular engorgement of the pelvis, constipation, prolonged standing, straining during stool
114
What is the cause of constipation in the second trimester
decreased bowel motility due to increased progesterone levels, diet, decreased fluids, lack of exercise
115
What is the cause of varicose veins in the second trimester
family history, obesity, the weight of the uterus compresses venous return causing stasis, prolonged standing
116
What is the cause of leg cramps in the second trimester
imbalance of calcium/phosphorus ratio, low magnesium levels, increased pressure of the uterus on nerves
117
What is the cause of ankle edema
prolonged sitting/standing, increased levels of sodium due to hormonal influences, circulatory congestion
118
What is the cause of backaches in the second trimester
increased curvature of the lumbosacral spine as the uterus enlarges, softening of cartilage from increased hormone levels, poor body mechanics, preterm contractions
119
How does a doppler transducer work
high frequency sound waves reflect the mechanical movement of the fetal heart, need to use gel
120
Tocotransducer (toco)
pressure-sensitive device that detects changes in abdominal contour to measure uterine activity (non-invasive), assess the frequency and duration of contractions and relative intensity and uterine resting tone
121
Baseline variability
