Chapter 10: Antepartum Fetal Assessment
MULTIPLE CHOICE
1. A pregnant client’s biophysical profile score is 8. She asks the nurse to explain the results. What is the
nurse’s best response?
a. “The test results are within normal limits.”
b. “Immediate birth by cesarean birth is being considered.”
c. “Further testing will be performed to determine the meaning of this score.”
d. “An obstetric specialist will evaluate the results of this profile and, within the next
week, will inform you of your options regarding birth.”
The normal biophysical score ranges from 8 to 10 points if the amniotic fluid volume is adequate. Scores
less than 4 would be investigated, and birth could be initiated sooner than planned.
2. Which analysis of maternal serum may predict chromosomal abnormalities in the fetus?
a. Biophysical profile
b. Multiple-marker screening
c. Lecithin-to-sphingomyelin ratio
d. Blood type and crossmatch of maternal and fetal serum
The multiple-marker screening may predict chromosomal defects in the fetus. The biophysical profile is
used to evaluate fetal status during the antepartum period. Five variables are used, but none are
concerned with chromosomal problems. The lecithin-to-sphingomyelin ratio is used to determine fetal
lung maturity. The blood type and crossmatch will not predict chromosomal defects in the fetus.
3. The clinic nurse is obtaining a health history on a newly pregnant client. Which is an indication for
fetal diagnostic procedures if present in the health history?
a. Maternal diabetes
b. Weight gain of 25 lb
c. Maternal age older than 30
d. Previous infant weighing more than 3000 g at birth
Diabetes is a risk factor in pregnancy because of possible impairment of placental perfusion.

, 4. When is the most accurate time to determine gestational age through ultrasound?
a. First trimester
b. Second trimester
c. Third trimester
d. No difference in accuracy among the trimesters
5. The primary reason for evaluating alpha-fetoprotein (AFP) levels in maternal serum is to determine
whether the fetus has which?
a. Hemophilia
b. Sickle cell anemia
c. A neural tube defect
d. A normal lecithin-to-sphingomyelin ratio
6. When is the earliest that chorionic villus sampling can be performed during pregnancy?
a. 4 weeks
b. 8 weeks
c. 10 weeks
d. 12 weeks
Fetal villus tissue can be obtained as early as 10 weeks of gestation and can be analyzed directly for
chromosomal or genetic abnormalities. It is too early to be performed at 4 weeks. It is too early to be
performed at 8 weeks. The test should be performed at 12 weeks, but it can be done as early as 10
weeks.
7. On which aspect of fetal diagnostic testing do parents usually place the most importance?
a. Safety of the fetus
b. Duration of the test
c. Cost of the procedure
d. Physical discomfort caused by the procedure
