The nurse’s best response is a. “The test results are within normal limits.” b. “Immediate delivery by cesarean birth is needed.” c. “Further tests are needed to determine the meaning of this score.” d. “We will inform you of your options within the next week.” 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. Delivery can be delayed if fetal well-being is indicated. An immediate delivery is not needed. The results of the biophysical profile are usually available immediately after the procedure is performed.

Which analysis of maternal serum may predict chromosomal abnormalities in the fetus? a. Multiple-marker screening b. Lecithin/sphingomyelin (L/S) ratio c. Biophysical profile d. Type and crossmatch of maternal and fetal serum ANS: A Maternal serum can be analyzed for abnormal levels of alpha-fetoprotein, human chorionic gonadotropin, and estriol. This multiple-marker screening may predict chromosomal defects in the fetus. The L/S ratio is used to determine fetal lung maturity. A biophysical profile is used for evaluating fetal status during the antepartum period. Five variables are used, but none is concerned with chromosomal problems. The blood type and crossmatch will not predict chromosomal defects in the fetus.
