What is shortening fraction?
Index of ventricular systolic function.
One of the most important cardiac measurements
Should be >25%
Gallbladder
Fills at about 17 wks gest when bile is being produced
Termination point of the left umbilical vein
Portal sinus
What is the ratio of the kidney circumference to the abdominal circumference?
.27-.30
There is a higher incidence of umbilical cord herniation when the fetus is in a:
Footling breech
If the foot and lower leg are seen on the same plane, what is the condition?
Clubfoot
In the 3rd trimester, a small amount of fluid in the renal collecting system may be a normal finding
True
Measurement in the collecting system that may be associated w an increased incidence of urinary tract obstruction
> 10mm

The major functioning unit of the placenta is the:
Chorionic villi
Another name for succenturiate lobe
Placenta membranacea
The maternal blood supply to the placenta is via the:
Spiral arterioles
The spiral arterioles are branches of the:
Uterine arteries
What hormones does the placenta produce?
HCG
Estrogen
Progesterone
What is associated with an abnormally thick placenta?
Rh sensitivity
Gest diabetes
Congenital neoplasm
The outer membrane of the placenta is the
Chorionic membrane
Spontaneous rupture of the amniotic membrane may result in:
Placental abruption
Oxygenated blood is carried to the fetus via the:
Umbilical vein
What is associated with 2-vessel cords
Congenital anomalies
Chromosomal anomalies
IUGR
Premature delivery
Hemangiomas of the umbilical cord are usually located:
At the placental end of the cord
When there is a marginal insertion of the umbilical cord it is referred as:
Battledore placenta
What is associated with a short cord?
Placental abruption
Abd wall defects
Intrafunicular hemorrhage
False nots of the umbilical cord are not clinically significant
True
A high systolic to diastolic ratio on the Doppler study of the cord is associated with:
IUGR
Maternal diabetes
Maternal HTN
Rh sensitivity
A high pressure bleed of the placenta or rupture of the spiral arteries is a:
Retroplacental abruption
A grade 3 placenta prior to 35 weeks may be associated with:
IUGR
Placental insufficiency
Smokers
HTN
Most common cause for a marginal abruption:
Decidual necrosis caused by cigarette smoking
Breu’s mole
A massive subchorial thrombosis
Placenta accreta
When the chorionic villi directly contact the myometrium
Grade 3 placenta is not usually seen until after:
35 weeks gest
Associated findings of a grade 0 placenta throughout the pregnancy
Rh factors
Gestational diabetes
Placental abruptions can be ruled in but not ruled out with sonography
True
