During a nonstress test (NST), a monitor records fetal heart rate when the mother senses fetal movement. This test is used to assess:

a. The effects of maternal drugs on the fetus
b. Maturity of the fetal heart and lungs
c. Fetal response to uterine contractions
d. Fetal oxygenation and autonomic function

Question 2

An elevated alpha-fetoprotein (AFP) level is consistent with:

a. Chromosomal disorders
b. Neural tube defects
c. High stress level
d. Poor placental function

Answer to Question 1

ANS: D
Increased fetal heart rate associated with movement reflects normal ability of the heart to speed up to meet increased oxygen demands. The contraction stress test (CST) assesses fetal response to uterine contractions. Fetal lung maturity is determined by testing amniotic fluid.

Answer to Question 2

ANS: B
An elevated AFP level is found with neural tube defects such as spina bifida or anencephaly. Low levels are associated with chromosomal abnormalities.
