MULTIPLE CHOICE
1. A pregnant womans biophysical profile score is 8. She asks the nurse to explain the results. The nurses best
response is
a. The test results are within normal limits.
b. Immediate delivery 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 delivery.
ANS: A
Feedback
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. Delivery can be
delayed if fetal well-being is indicated.

B Scores less than 4 should be investigated, and delivery could be initiated sooner than planned.
C This score is within normal range, and no further testing is required at this time.

performed.

Feedback
A Maternal serum can be analyzed for abnormal levels of alpha-fetoprotein, human chorionic
gonadotropin, and estriol. The multiple-marker screening may predict chromosomal defects
in the fetus.
B The L/S ratio is used to determine fetal lung maturity.
C A biophysical profile is used for evaluating fetal status during the antepartum period. Five
variables are used, but none is concerned with chromosomal problems.
D The blood type and crossmatch will not predict chromosomal defects in the fetus.

B A maternal age greater than 35 years is an indication for testing.
C Having had another infant weighing greater than 4000 g at birth is an indication for testing.
D Excessive weight gain is an indication for testing. Normal weight gain is 15 to 35 pounds.
