And Answers | Complete Tests Solutions
While performing a scan on a 27 week fetus, you see echogenic foci in the liver and a thick walled cyst in the
fetal abdomen. Several small bowel loops appear dilated with limited peristalsis. Fetal ascites and
polyhydramnios are also present. These findings are most consistent with: ANS meconium peritonitis
All of the following statements regarding fetal hydrops are true, except: ANS non-immune and immune
fetal hydrops can be distinguished from one another by their very different sonographic
appearance/characteristics
Esophageal atresia is a significant indication for which of the following Trisomies? ANS 18
In a 32 week pregnancy, a cervix that is less than ______ in length and dilated more than ______ is considered
incompetent. ANS 3cm, 2cm
In the 2nd trimester, documenting a normal lens in each eye on the fetal ultrasound can rule out which of the
following abnormalities? ANS cataracts
What is the most common cause of death in lethal skeletal dysplasia? ANS pulmonary hypoplasia
What maternal condition has been linked to umbilical vein thrombosis? ANS diabetes
Macrosomia describes a fetus weighing more than ANS 4000g
The AV canal defect is the combination of an ANS ostium primum ASD and an inlet VSD
You are evaluating the aortic arch and descending aorta on a 25 week fetus. There is a narrowing of the aorta
just below the origin of the left subclavian artery. Color Doppler demonstrates aliasing at the narrowed area
with some flow moving distally in the descending aorta. Which of the following best describes these findings?
ANS coarctation
A patient presents at 20 weeks for suspected Eagle Barrett Syndrome. Which of the following fetal structures
should be closely evaluated for the cause? ANS kidneys and bladder
,What delivery complication is most commonly associated with velamentous cord insertion? ANS vasa
previa
Which of the following correctly describes the sonographic appearance of the pump twin in a twin reversed
arterial perfusion sequence? ANS skin edema, ascites, congestive heart failure
Polyhydramnios is diagnosed when the four quadrant fluid level is greater than ANS 25cm
You are evaluating the heart on a 28 week fetus. A single large trunk vessel exits the heart and the pulmonary
artery appears to branch from it instead of from the right ventricle. These findings describe ANS truncus
arteriosus
Which of the following is most suggestive of holoprosencephaly? ANS cebocephaly
Which of the following is true regarding autosomal dominant polycystic kidney disease? ANS if it occurs
in a fetus, at least one parent has ADPKD
You are performing a follow up exam for limited fetal anatomy of the last US with non-visualization of the
stomach and kidneys at 15wks. The fetus should be 21 weeks today. On today's exam, you identify a single
normal kidney but the stomach is barely visible and very small. Borderline polyhydramnios is also present.
The head measures 3 standard deviations lower than the abdomen and femoral measurements. Rocker bottom
feet are also present. These findings are most consistent with ANS Trisomy 18
The most commonly reported intrauterine infection in pregnancy is ANS cytomegalovirus
You are performing a follow up exam for limited fetal anatomy of the last US with non-visualization of the
stomach and kidneys at 15wks. The fetus should be 21 weeks today. You identify two normal kidneys but the
stomach is barely visible and very small. Borderline polyhydramnios is also present. These findings are most
suggestive of ANS esophageal atresia
While performing a scan on a 21 week fetus you identify ectopia cordis, club foot and an asymmetric cleft
lip/palate. Which of the following is the most likely cause of these findings? ANS amniotic band sequence
Which of the following is the most common facial anomaly? ANS cleft lip/palate
, Which anomaly is almost always associated with a tracheoesophageal fistula? ANS esophageal atresia
Which of the following skeletal anomalies usually occurs as an isolated finding? ANS talipes equinovarus
What is the most commonly identified fetal chest mass? ANS congenital cystic adenomatoid malformation
(CCAM)
What is the most common congenital cardiac anomaly? ANS ventricular septal defect
An encephalocele can easily be mistaken for ANS cystic hygroma
The most common cardiac defect seen with trisomy 21 is? ANS AV canal defect or AVSD
A trident hand is commonly seen with which skeletal abnormality? ANS heterozygous achondroplasia
While scanning a 21 week fetus, you identify splaying of cerebellar lobes with absence of the cerebellar lobes
with absence of the cerebellar vermis. The 13mm cisterna magna is anechoic and the 4th ventricle is dilated.
These findings are most consistent with ANS Dandy walker malformation
When evaluating the abdominal circumference of a 30 week fetus, you note that the umbilical vein curves to
the left toward the stomach and the gallbladder is medial to the vein. The AC measurement and the skin
thickness are normal. These findings are most suggestive of ANS persistent right umbilical vein
Asymmetric IUGR ANS involves shunting of arterial blood flow from the abdomen to the brain
If you identify hypoplastic left heart in a female fetus, what fetal syndrome should be suspected? ANS
turner
All of the following can cause a false positive diagnosis of club foot, except ANS uncooperative fetus
