Question 1
What is the sonographic appearence of a monochorionic-diamniotic pregnancy?
A
Single chorionic sac, yolk sac and amnion are shared by both embryos.
B
Single gestational sac, 1 amniotic membrane, may contain 1 or 2 yolk sacs, and 2 embryos within the single amniotic membrane.
C
Each gestational sac has an INDIVIDUAL yolk sac, amniotic membrane and embryo.
D
Contained within one chorionic sac, 2 amnions, 2 yolk sacs, 2 embryos.
Question 2
What percentage of Teratomas occur in women of childbearing age?
A
68%
B
80%
C
25%
D
95%
Question 2 Explanation: 
Dermoid cyst or teratoma is the most common germ cell tumor, comprising 20% of ovarian tumors. The tumor has been found in young children although about 80% occur in women of childbearing age.
Question 3
Explain stage 1 ovarian cancer:
A
Cancer cells are found in one or both ovaries. Cancer cells may be found on the surface of the ovary or in abdominal free fluid.
B
Cancer cells have spread to other tissue in the pelvis such as the Fallopian tubes, the Uterus or other tissue.
C
Cancer cells have spread outside the abdomen and pelvis. They may be found within the liver, the lungs or any other organ or lymph node.
D
Cancer cells have spread outside the pelvis to other tissue or even regional lymph nodes. These cells may be found on the surface of the liver.
Question 4
What is the purpose of a Sonohysterogram?
A
To evaluate the competency of the cervix
B
To evaluate the myomtrium
C
To evaluate patency of fallopian tubes
D
To evaluate endometrial contents
Question 4 Explanation: 
A Sonohysterogram (aka Hysterosonogram or Sonohystogram) is performed to evaluate the contents of the endometrium. A "goldstein" catheter is used to inject water into the endometrial cavity and evaluate suspicious areas for polyps.
Question 5
What is the most accurate measurement when the embryo is 12 weeks or older in first trimester?
A
\(\displaystyle{head circumference}\)
Hint:
You're getting closer!
B
bi-parietal diameter
Hint:
This is more accurate than the crown rump length :)
C
\(\displaystyle{abdomen circumference}\)
Hint:
This is the LEAST accurate measurement to date an embryo in first trimester.
Question 5 Explanation: 
This is something people tend to overlook because we have instilled our heads to measure the crown rump length at first trimester.
Question 6
Endometriomas are also known as.
A
Functioning cyst
B
Theca Lutein Cysts
C
Chocolate cyst
D
Tubo-Ovarian Abcess (TOA)
Question 7
Tubo-Ovarian Abcess (TOA)
A
Dysmenorrhea
B
Endometritis
C
Chocolate cyst formation
D
Theca Lutein Cysts
Question 7 Explanation: 
Endometritis can be divided into pregnancy-related endometritis and endometritis unrelated to pregnancy. When the condition is unrelated to pregnancy, it is referred to as pelvic inflammatory disease (PID).
Question 8
Which benign adnexal cyst is associated with high levels of hCG?
A
Polycystic Ovarian disorder
B
Hydrosalpinx
C
Chocolate cysts
D
Theca-Lutein Cysts
Question 9
When should the corpus luteum resolve?
A
\(\displaystyle{14-16 weeks}\)
B
\(\displaystyle{8-10 weeks}\)
C
\(\displaystyle{12- 14 weeks}\)
D
10- 12 weeks
Question 10
Explain stage 2 ovarian cancer:
A
Cancer cells are found in one or both ovaries. Cancer cells may be found on the surface of the ovary or in abdominal free fluid.
B
Cancer cells have spread outside the abdomen and pelvis. They may be found within the liver, the lungs or any other organ or lymph node.
C
Cancer cells have spread to other tissue in the pelvis such as the Fallopian tubes, the Uterus or other tissue.
D
Cancer cells have spread outside the pelvis to other tissue or even regional lymph nodes. These cells may be found on the surface of the liver.
Question 11
These Muscles pass out from the pelvis through the Sciatic Foramina to attach to the Greator Tuberosity of the Femor.
A
The Superior and Inferior Gemellus Muscles
B
The Piriformis and Obturator Internus muscles
C
Quadratus Femoris
D
Obturator Externus
Question 12
Early sexual contact, multiple sex partners, history of stds and/or douching are all risk factors are associated with what disease?
A
Pelvic Inflammatory Disease (PID)
B
Endometriosis
C
Polycystic ovarian syndrome (POS)
D
Leiomiomas
Question 13
Pelvic Inflammatory Disease (PID), endometriosis and post operative adhesions can all cause what?
A
Hydrosalpinx
B
Leiomiomas
C
Ectopic Pregnancy
D
Tubo-Ovarian Abcess (TOA)
Question 14
What structures produce amniotic fluid in the first trimester?
A
Kidneys and umbilical cord
B
Kidneys and placenta
C
Placenta, amnion, umbilical cord, skin
D
Placenta
Question 14 Explanation: 
During the first trimester, the amniotic fluid composition is similar to that of fetal plasma. There is bi-directional diffusion between the fetus and the amniotic fluid across the skin that is not keratinized yet, and the surface of the amnion, placenta, and umbilical cord being freely permeable to water and solutes. Neither fetal urination nor swallowing contribute significantly to the amniotic fluid volume until 14 weeks of pregnancy.
Question 15
20-40% of female infertility is caused by what?
A
Prior Infection
B
Congenital Anomaly
C
Retroverted Uterus
D
Tubal Obstruction
Question 16
What structures produce amniotic fluid in the second and third trimester?
A
Kidneys, lungs
B
Kidneys and placenta
C
Kidneys only
D
Kidneys, bladder and umbilical cord
Question 16 Explanation: 
Keratinization of fetal skin begins at 19 to 20 weeks of gestation and is usually complete at 25 weeks after conception. Numerous factors contribute to the formation and removal of amniotic fluid following keratinization of the fetal skin. Production of amniotic fluid is predominately accomplished by the fetal urine and lung fluid production.
Question 17
What is the interventional ultrasound method used for a deep pelvic abscess?
A
Transvaginal drainage
B
Percutaneous drainage
C
Transabdominal drainage
D
What is the interventional ultrasound method used for a deep pelvic abscess?
Question 18
What is the most common of the infection that causes Pelvic Inflammatory Disease (PID)?
A
Endometritis
B
Transmission through Sexual Intercourse
C
Post Surgical Infection
D
IUD
Question 19
The removal of the uterus (cervix, ovaries and fallopian tubes are left)
A
Total Hysterectomy
B
Bilateral Salpingoophorectomy
C
Partial Hysterectomy
D
Total Oopherectomy
Question 20
Any patient diagnosed with PID will have a greater risk of what complication?
A
Endometriosis
B
Endometrial Hyperplasia
C
Theca Lutein Cysts
D
Ectopic Pregnancy
