At 17 weeks' gestation, a type I diabetic undergoes an ultrasound examination. What information about the fetus at this time in pregnancy will the results of this examination provide?
a. Estimated fetal weight c. Gestational age
b. Fetal lung maturity d. Placental maturity
C
The primary purpose for performing ultrasound at 17 weeks' gestation is to determine gestational age of the fetus. Although estimated fetal weight may be obtained through ultrasound, it is not the most important factor. At 17 weeks, fetal lung maturity is not an ultrasound finding. Placental maturity is not an ultrasound finding at 17 weeks' gestation.
