If you were her gynecologist, which of the following prenatal tests would you recommend to either confirm or rule out the number of babies she is carrying?

a.quadruple maternal blood testc.chorionic villus sampling

b.amniocentesisd.ultrasound

74.If you were most interested in knowing the genotype of your unborn baby, perhaps to find out if there were specific genetic or chromosomal problems, which prenatal test would be most appropriate?

a.ultrasoundc.amniocentesis

b.maternal glucose testd.chorionic villus sampling

75.If you are pregnant and want to get a prenatal test to assess various aspects of your unborn child’s well-being, which of the following should you avoid if you suffer from trypanophobia (or the fear of needles)?

76.A procedure that involves removing a sample of tissue from part of the placenta that is done 9 to 12 weeks into a pregnancy is called

a.amniocentesis.c.ultrasound.

b.chorionic villus sampling.d.maternal glucose test.

77.Why would a person be naturally concerned about undergoing an amniocentesis or chorionic villus sampling during their pregnancy?

a.Because a miscarriage is 1–2% more likely after these tests.

b.Because the results from both tests take two to four weeks to obtain.

c.Because they are both rather painful, while an ultrasound is noninvasive and painless.

c.Fixing Birth Defects Before Birth.

d.The Importance of Childhood Inoculations.

79.What is the current status of the use of genetic engineering to help treat illnesses that are caused by defective genes?

a.Genetic engineering is still illegal in the United States, though other countries are using it on a routine basis.

b.Genetic engineering has been found useful for metabolic disorders, but only when employed prior to the fetal stage of prenatal development.

c.Some successful applications of genetic engineering have been seen with older children.

d.Genetic engineering has never been successfully used in animals or human beings, but the theories are sound and research is ongoing.
