Obstetrics and Gynecology Mock Exam
Final Exam- Latest Exam 2026/2027
with 100% Verified Q&A | Graded A+
Question 1
A cloverleaf-shaped cranium in a second trimester fetus is characteristic of:
Choices:
a) Anencephaly
b) Fetal demise
c) Oligohydramnios
d) Skeletal dysplasia
Correct Answer: d) Skeletal dysplasia
Explanation: A cloverleaf shape to the skull is characteristic of skeletal dysplasia
(thanatophoric dwarf). Overlapping of the calvarium bones is present with long-
standing fetal demise termed Spalding sign.
Question 2
Which genitourinary abnormality depends on fetal gender?
Choices:
a) Infantile polycystic disease
b) Multicystic dysplastic kidney
c) Ureteropelvic junction obstruction
d) Posterior urethral valve obstruction
Correct Answer: d) Posterior urethral valve obstruction
Explanation: The presence of valves within the male urethra results in a urinary
obstruction demonstrating a dilated bladder and posterior urethra (keyhole sign).
,Question 3
Which pelvic structure contains the uterine blood vessels and nerves?
Choices:
a) Psoas muscles
b) Broad ligament
c) Ovarian ligaments
d) Suspensory ligaments
Correct Answer: b) Broad ligament
Explanation: The broad ligament provides a small amount of support for the uterus
and contains the uterine blood vessels and nerves. The suspensory ligaments contain
the ovarian vessels.
Question 4
When the vascular space between the placenta and myometrium is absent, the
sonographer should suspect:
Choices:
a) Placenta accreta
b) Placenta abruptio
c) Circumvallate placenta
d) Umbilical vein thrombosis
Correct Answer: a) Placenta accreta
Explanation: Placenta accreta is a condition where the chorionic villi invade the
superficial layer of the uterine myometrium, obliterating the retroplacental complex.
Question 5
Measurement of the biparietal diameter is taken at a level to include the:
Choices:
a) Falx cerebri
b) Cisterna magna
,c) Fourth ventricle
d) Thalamic cerebri
Correct Answer: d) Thalamic cerebri
Explanation: Identification of the falx does not indicate the proper level for the
biparietal diameter (BPD). Measurement of the BPD is at a level passing through the
third ventricle and thalamic cerebri. Other landmarks include the cavum septum
pellucidi and the atrium of the lateral ventricle.
Question 6
The best measuring method for evaluating gestational age is the:
Choices:
a) Femur length
b) Biparietal diameter
c) Crown-rump length
d) Head circumference
Correct Answer: c) Crown-rump length
Explanation: Crown-rump length during the first trimester is generally the best and
most accurate method for measuring gestational age.
Question 7
Bilateral symmetric pelvic masses are most likely:
Choices:
a) Pelvic muscles
b) Follicular cysts
c) Theca lutein cysts
d) Uterine leiomyomas
Correct Answer: a) Pelvic muscles
Explanation: Symmetric bilateral pelvic masses are most likely pelvic muscles.
Bilateral follicular cysts, theca lutein cysts, or uterine fibroids are not likely
symmetrical.
, Question 8
A localized hypoechoic adnexal mass is present on serial sonograms. Physiological
ovarian cysts of varying size are present bilaterally. Based on this clinical history, the
adnexal mass is most suspicious for a(n):
Choices:
a) Dermoid cyst
b) Endometrioma
c) Parovarian cyst
d) Hemorrhagic cyst
Correct Answer: b) Endometrioma
Explanation: A hypoechoic adnexal mass separate from the ovaries is most
suspicious for an endometrioma. A complicated parovarian cyst is a differential
consideration but is not the likely diagnosis.
Question 9
Maintaining privacy of a patient's medical and personal information is a primary
concern of the:
Choices:
a) Patient Care Partnership
b) Joint Review Committee
c) Agency for Healthcare Research and Quality
d) Health Insurance Portability and Accountability Act
Correct Answer: d) Health Insurance Portability and Accountability Act
Explanation: HIPAA is a federal agency overseeing many healthcare functions, the
primary being patient confidentiality.
