Ch. 32 The Fetal Face and Neck Flashcards
The maternal contribution to the placenta is the: Chorionic vera Decidua vera Decidua basalis Chorion frondosum
Decidua basalis
The placenta releases _________ to maintain the corpus luteum.
- hCG
- FSH
- LH
- Gonadotropin-stimulating hormone
hCG
An anechoic mass is noted w/in the umbilical cord during a routine sonographic exam. What's the most likely diagnosis? Hemangioma Vasa previa Chorioangioma Allantoic cyst
Allantoic cyst
Mothers w/ pregestational diabetes, as opposed to gestational diabetes, have an increased risk of a fetus w/: Neural tube defects Proteinuria TORCH DES
Neural tube defects
A succenturiate lobe of the placenta refers to as:
- Bilobed placental lobe
- Circumvallate placental lobe
- Accessory lobe
- Circummarginate placental lobe
Accessory lobe
Pools of maternal blood noted w/in the placental substance are referred to as: Accessory lobes Decidual casts Chorioangiomas Maternal lakes
Maternal lakes
The fetal contribution to the placenta is the: Chorionic vera Decidua vera Decidua basalis Chorion frondosum
Chorion frondosum
The placenta is considered too thick when it measures: >4mm >4cm >8mm >3.5cm
> 4cm
All of the following are associated w/ a thin placenta except: Preeclampsia IUGR Fetal hydrops Long-standing diabetes
Fetal hydrops
When the placental edge extends into the lower uterine segment but ends more than 2 cm away from the internal os, its referred to as:
- Low-lying previa
- Marginal previa
- Partial previa
- Total previa
Low-lying previa
One of the most common causes of painless vaginal bleeding in the 2nd and 3rd trimester is:
- Spontaneous abortion
- Abruptio placentae
- Placenta previa
- Placenta accreta
Placenta previa
All of the following are associated w/ a thick placenta except:
- Fetal infections
- Rh isoimmunization
- Placental insufficiency
- Multiple gestations
Placental insufficiency
Placenta accreta denotes:
- The abnormal attachment of the placenta to the myometrium
- The premature separation of the placenta from the uterine wall
- The invasion of the placenta into the myometrium
- The condition of having the fetal vessel rest over the internal os
The abnormal attachment of the placenta to the myometrium
Doppler sonography reveals vascular structures coursing over the internal os of the cervix. This finding is indicative of: Vasa previa Placenta previa Placenta increta Abruptio placentae
Vasa previa
All of the following are clinical features of placental abruption except:
- Vaginal bleeding
- Uterine tenderness
- Abdominal pain
- Funneling of the cervix
Funneling of the cervix
All of the following are associated w/ oligohydramnios except:
- Bilateral renal agenesis
- Infantile polycystic kidney disease
- Premature rupture of membranes
- Duodenal atresia
Duodenal atresia
The most common placental tumor is the: Choriocarcinoma Maternal lake Chorioangioma Allantoic cyst
Chorioangioma
The normal umbilical cord has:
- One vein and one artery
- Two veins and two arteries
- Two veins and one artery
- Two arteries and one vein
Two arteries and one vein
Insertion of the umbilical cord at the edge of the placenta is referred to as:
- Velamnetous cord insertion
- Partial cord insertion
- Marginal cord insertion
- Nuchal cord insertion
Marginal cord insertion
Increased S/D ratio is associated w/ all of the following except: IUGR Placental insufficiency Allantoic cysts Perinatal mortality
Allantoic cysts
A velamentous cord insertion is associated w/ which of the following? Placenta increta Placental abruption Vasa previa Circumvallate placenta
Vasa previa
Normally, the S/D ratio:
- Increases w/ advancing gestation
- Decreases w/ advancing gestation
- Reverses occasionally during a normal pregnancy
- Has an absent diastolic component
Decreases w/ advancing gestation
Fetal TORCH is frequently associated w/:
- Maternal hypertension
- Twin-twin transfusion syndrome
- Intracranial calcifications
- Renal cystic disease
Intracranial calcifications
Evidence of polyhydramnios should warrant a careful investigation of the fetal:
- Genitourinary system
- Gastrointestinal system
- Extremities
- Cerebrovascular system
Gastrointestinal system
All of the following are associated w/ polyhydramnios except:
- Omphalocele
- Gastroschisis
- Esophageal atresia
- Bilateral multicystic dysplastic kidney disease
Bilateral multicystic dysplastic kidney disease
IUGR is evident when the EFW is:
- Above the 90th percentile
- Below the 90th percentile
- Above the 10th percentile
- Below the 10th percentile
Below the 10th percentile
The cervix should measure at lease \_\_\_\_\_ in length. 4cm 5cm 3cm 8mm
3cm
The measurement that should be carefully scrutinized in cases of IUGR is the: AC FL BPD HC
AC
Doppler assessment of the middle cerebral artery:
- Helps to determine if fetal anorexia is occurring
- Is valuable in diagnosing the extent of ventriculomegaly
- Can evaluate the fetus for hypoxia
- Is important to determine if TORCH complications are present
Can evaluate the fetus for hypoxia
Mothers w/ gestational diabetes run the risk of having fetuses that are considered: Nutritionally deficient Acromegalic Microsomic Macrosomic
Macrosomic
