Fetal Growth Abnormalities

Question 1

What can be used to evaluate pregnancy complicated by fetal growth restriction?

Answer 1

amniotic fluid volume, umbilical artery Doppler studies, non-stress test

Question 2

What does BPP evaluate?

Answer 2

fetal movement, fetal tone, amniotic fluid, and breathing

Question 3

What to do if preterm IUGR detected?

Answer 3

NSTs should be performed twice weekly with at least a weekly AFI, BPP may be performed weekly

Question 4

Ultrasound for fetal growth is not useful to detect a difference if performed more frequently than ___.

Answer 4

every 2 weeks

Question 5

In order to accurately confirm gestational age at term, one of the following criteria should be met:

Answer 5

fetal heart tones have been documented for 20 weeks by non electronic fetoscope or for 30 weeks by Dopper; it has been 36 weeks since positive serum or urine HCG test performed by reliable laboratory; ultrasound measurement of crown rump lenght obtained at 6 to 12 weeks, supports gestational age of at least 39 weeks, determined by clinical history and physical exam. Crown rump length can reliably date a pregnancy within 5 to 7 days.

Question 6

abnormal fetal swallowing may be a result of :

Answer 6

CNS or GI tract abnormalities, such as anencephaly, esophageal or duodenal atresia, diaphragmatic hernia or primary muscular disease

Answer 7

cardiovascular disease, chronic hypertension, stroke, chronic obstructive lung disease, type 2 diabetes, obesity, cognitive delay in childhood

Question 8

what is growth restriction definition by percentile?

Answer 8

fetal weight less than 10th percentile

Question 9

The fetus with macrosomia is defined by:

Answer 9

birth weight at or above the 90th percentile for gestational age

Question 10

what is the best option for estimating fetal weight?

Answer 10

obstetric ultrasound
