Central
The normal umbilical insertion portion into he placentae is:
>4cm
The placenta is considered too thick when it measures?
Human Chorionic Gonadotropin

Red Blood cells
What Rh isoimmunization, the maternal antibodies cross the placenta and destroy the fetal:
Leiomyoma
What is NOT associated with immune hydrops: a. fetal hepatomegaly b. fetal splenomegaly c. anasarca d. leiomyoma
low-lying placenta
What is it when the placental edge extends into the lower uterine segment but ends more than 2cm away from the internal os.
myometrial contrations
What would be most likely confused for a uterine leiomyoma?
Total Previa
When the placenta completely covers the internal os, it is referred to as:
previous cesarean section
Which of the following would increase the likelihood of developing placenta previa a. vaginal bleeding b. previous caesarean section c. corpus albicans d. chorioangioma
Allantoic cysts
increased S/D ratio is associated with all of the following except: a. placenta increate b. placental abruption c. vasa previa d. circumvallate placenta
Decidua basalis
maternal contribution to the placenta
Accessory Lobe
A succenturiate lobe of the placenta refers to a:
Vasa previa
A velamentous cord insertion is associated with:
placental insufficiency
All of the following are asso. with a thick placenta except: a. fetal infectons b. Rh isoimmunization c. Placental insufficiency d. Multiple gestations
fetal hydrops
All of the following are associated with a thin placenta EXCEPT: a. preeclampsia b. IUGR c. fetal hydrops d. long standing diabetes
Duodenal atresia
All of the following are associated with oligohydramnios EXCEPT: a. Bilateral renal agenesis b. IPKD c. premature rupture of membranes d. duodenal atresia
bilateral Multicystic dysplastic kidney disease
All of the following are associated with polyhydramnios except: a. omphalocele b. gastroschisis c. esophageal atresia d. Bilateral Multicystic dysplastic kidney disease
Funneling of the cervix
All of the following are clinical features of placental abruption except: a. vaginal bleeding b. uterine tenderness c. abd pain d. funneling of the cervix
Allantoic Cyst
An anechoic mass is noted within the umbilical cord during a routine sonographic examination. What is most likely the diagnosis?
Hypoxia
Doppler assessment of the middle cerebral artery can evaluate the fetus for ________________.
Vasa Previa
Doppler sonography reveals vascular structures coursing over the internal os of the cervix. This finding is indicative of: A. Vasa previa B. Placenta previa C. Placenta increta D. Abruptio placentae
Gastrointestinal System
Evidence of polyhydramnios should warrant a careful investigation of the fetal ___________________________ system.
Intracranial calcification
Fetal TORCH is frequently associated with:
Below the 10th percentile
IUGR evident when the EFW is:
Marginal cord insertion
Insertion of umbilical cord at edge of placenta
Macrosomic
Mothers with gestational diabetes run the risk of having fetuses that are considered:
Neural tube defects
Mothers with pregestational diabetes, as opposed to gestational diabetes, have an increased risk of a fetus with?
Pleural effusion, Turner syndrome, & Fetal infections
Nonimmune hydrops is associated with:
Decreases
Normally the S/D ratio __________________________ with advancing gestation.
Placenta previa
One of the most common causes of painless vaginal bleeding in the second and third trimester
Placenta percreta
Penetration of the placenta beyond the uterine wall would be referred to as:
Maternal leakage
Pools of maternal blood noted within the placental substance are refereed to as:
preeclampsia
Pregnancy-induced maternal high blood pressure and excess protein in the urine after 20 weeks gestation is termed.
