Answer to Question 1

ANS: A
Gestational age determination by ultrasonography is increasingly less accurate after the first trimester. Gestational age determination is best done in the first trimester. There is a difference in trimesters when doing a gestational age ultrasonography.

Answer to Question 2

ANS: A
The normal biophysical score ranges from 8 to 10 points if the amniotic fluid volume is adequate. A normal score allows conservative treatment of high-risk patients. Birth can be delayed if fetal well-being is an issue. Scores less than 4 would be investigated, and birth could be initiated sooner than planned. This score is within normal range, and no further testing is required at this time. The results of the biophysical profile are usually available immediately after the procedure is performed.
