Prior to an amniocentesis, a fetal ultrasound is done in order to:

  1. Evaluate fetal lung maturity
  2. Evaluate the amount of amniotic fluid
  3. Locate the position of the placenta and fetus
  4. Ensure that the fetus is mature enough to perform the amniocentesis

Answer(s): C

Explanation:

(A) Amniocentesis can be performed to assess for lung maturity. Fetal ultrasound can be used for gestational dating, although it does not separately determine lung maturity. (B) Ultrasound can evaluate amniotic fluid volume, which may be used to determine congenital anomalies. (C) Amniocentesis involves removal of amniotic fluid for evaluation. The needle, inserted through the abdomen, is guided by ultrasound to avoid needle injuries, and the test evaluates the position of the placenta and the fetus. (D) Amniocentesis can be performed as early as the 15th­17th week of pregnancy.
