OBGYN Quiz 3 Flashcards
What are three things that are usually associated with placental abruption?
-premature labor
-Severe maternal trauma
-Fetal distress
Note: NOT “oligohydramnios”
What are three common causes of spotting in the first trimester?
-Ectopic pregnancy
-Implantation
-Molar pregnancy
Note: NOT “Multiple Gestation”
Your next patient is in the department for a follow up from her procedure to evacuate a complete hydatidiform mole. Before her appointment she stopped at the lab to have her hCG drawn, which has not returned to zero following her procedure. The image below represents her findings on today’s exam.
What does it most likely represent?
Chorioadenoma destruens
What is the most common placental tumor?
Chorioangioma
What does the chorionic gonadotropin (hCG) levels higher than expected for gestational age suggest?
Trophoblastic disease
What would you expect to find in the adnexa of a patient who has a hydatidform mole?
Theca lutein cysts
Your next patient came to the emergency room with complaints of heavy bleeding and severe cramping.
She was seen by her OB/GYN two weeks ago and was told she was 10 weeks pregnant. While scanning her you find the image below. What does this most likely represent?
Imminent pregnancy loss
T/F
Bradycardia less than 120 bpm is associated with poor outcomes between 6.3 and 7 weeks gestation
True
What is a partial mole?
Associated with triploidy (which is lethal).
List the abnormal attachments of the placenta from least to most severe:
-Placenta Acreta
-Placenta Increta
-Placenta Percreta
(Pic)
Fetal papyraceus is a term used to describe:
The donor twin-to-twin transfusion syndrome
T/F
The most risky form of a placental abruption is due to the rupture of the spiral arteries. It causes a high pressure retroplacental bleed.
True
What is the type of conjoined twins that are connected at the chest?
Thoracopagus
What are three common risk factors for spontaneous abortion?
-maternal diabetes mellitus
-maternal smoking
-chromosomal abnormalities of the fetus
Note: NOT “endometriosis”
Which is a common fetal complication for both maternal diabetes mellitus and gestational diabetes?
Large for gestational age
Why do the material clinical signs and symptoms of hypertension, edema, and proteinuria represent?
Preeclampsia

What are 3 things you need to evaluate when imaging the placenta. One word answers will not get full credit. Do not mention any sort of mass.
- Placenta Cord Insert:
The ideal location for the chord to insert is though the center of the placenta. When the chord is inserted elsewhere, such as the outer edge of the placenta, it can lead to restricted blood flow to the baby. - Placental Location:
You need to determine if the placenta is in a normal position or if it’s low-lying, which could lead to complications such as placenta previa. - Placental Margins:
The margins (edges) of the placenta need to be evaluated for any signs of abnormal invasion into the uterine wall (such as in conditions like placenta accreta).
***Written
Tell me two different things that may suggest a heterotopic pregnancy
-hCG levels are abnormal
-Pelvic pain & vaginal bleeding
T/F
In a twin pregnancy with poly-oli sequence, the twin with the polyhydramnios does not have complications
False
What is the most common causes of intrauterine infections?
Cytomegalovirus
T/F
A small gestational sac results in a first trimester pregnancy loss in a reported 90% of cases.
True
*** Describe Rh isoimmunization and who is it effecting.
How is it treated? You answer needs to be specific for full credit.
Rh immunization effects Rh- mother and Rh+ baby.
Rh isoimmunization happens when an Rh-negative mother carries an Rh-positive fetus, causing her immune system to produce antibodies against the fetus’s Rh-positive blood cells.
This can be treated with RhGRAM, an injection given to the mother at 28 weeks of pregnancy and within 72 hours after the birth of an Rh-positive baby to prevent the development of antibodies.
In twin gestations, the TRAP sequence is the result of this kind of vascular anastomoses:
Artery of twin A to artery of twin B &
Vein of twin A to vein of twin B
