When describing the potential for misuse of genetic discoveries and advances, which of the following would the nurse include?

A) Gene replacement therapy for defective genes
B) Individual risk profiling and confidentiality issues
C) Greater emphasis on the causes of diseases
D) Slower diagnosis of specific diseases

Question 2

Prenatal testing is used to assess for genetic risks and to identify genetic disorders. In discussing an elevated alpha-fetoprotein screening test result with a couple, the nurse would discuss:

A) The special care needed for a Down syndrome infant
B) The need for a more specific determination of the acidbase status
C) The need for more definitive evaluations before making any conclusions
D) The need for immediate termination of the pregnancy

Answer to Question 1

B
Response:
Individual risk profiling based on an individual's genetic makeup can raise issues related to privacy and confidentiality. Gene replacement therapy for defective genes and a greater emphasis on the causes of disease are considered benefits associated with genetic advances. Rapid, more specific diagnosis of diseases would be possible with genetic advances.

Answer to Question 2

C
Response:
Increased maternal serum alpha-fetoprotein levels may indicate a neural tube defect, Turner syndrome, tetralogy of Fallot, multiple gestation, omphalocele, gastroschisis, or hydrocephaly. Therefore, additional information and more specific determinations need to be done before any conclusion can be made. Down syndrome is associated with decreased maternal serum alpha-fetoprotein levels. This type of testing provides no information about the acidbase status of the fetus. Immediate termination is not warranted; more information is needed.
