OBSTERICS AND GYNECOLOGY FINAL
MOCK EXAM STUDY QUESTIONS
CORRECTLY ANSWERED RATED A.
1.
A cloverleaf-shaped cranium in a second trimester fetus is characteristic of:
a.
anencephaly
b.
fetal demise
c.
oligohydramnios
d.
skeletal dysplasia
Verified Answer -1. d.
A cloverleaf shape to the skull is characteristic of skeletal dysplasia
(thanatophoric dwarf). Overlap-ping of the calvarium bones is pres-ent with long-
standing fetal demise termed
Spalding sign.
2.
Which genitourinary abnormality depends on fetal gender?
a.
infantile polycystic disease
b.
,multicystic dysplastic kidney
c.
ureteropelvic junction obstruction
d.
posterior urethral valve obstruction
Verified Answer -2. d.
The presence of valves within the
male urethra results in a urinary obstruction demonstrating a dilated bladder and
posterior urethra (keyhole sign)
3.
Which pelvic structure contains the uterine blood vessels and nerves?
a.
psoas muscles
b.
broad ligament
c.
ovarian ligaments
d.
suspensory ligaments
Verified Answer -3. b.
The broad ligament provides a small amount of support for the uterus and
contains the
uterine blood vessels and nerves.
The suspen-sory ligaments contain the ovarian vessels.
,4.
When the vascular space between the placenta and myometrium is absent, the
sonographer should suspect:
a.
placenta accreta
b.
placenta abruptio
c.
circumvallate placenta
d.
umbilical vein thrombosis
Verified Answer -4. a.
Placenta accreta is a condition where the chorionic villi invade the superficial
layer of the uterine myo-metrium, obliterating the retropla-cental complex.
5.
Measurement of the biparietal diameter is taken at a level to include the:
a.
falx cerebri
b.
cisterna magna
c.
fourth ventricle
d.
thalamic cerebri
Verified Answer -5. d.
, Identification of the falx does not indicate the proper level for the biparietal
diameter (BPD). Mea-surement of the BPD is at a level passing through the third
ventricle and thalamic cerebri. Other land-marks include the cavum septum
pellucidi and the atrium of the lat-eral ventricle.
.
6.
The best measuring method for evaluating gesta-tional age is the:
a.
femur length
b.
biparietal diameter
c.
crown-rump length
d.
head circumference
Verified Answer -6. c.
Crown-rump length during the first trimester is generally the best and most
accurate method for mea-suring gestational age.
7.
Bilateral symmetric pelvic masses are most likely:
a.
pelvic muscles
b.
follicular cysts
