Prenatal testing is used to assess for genetic risks and to identify genetic disorders. In explaining to a couple about an elevated alpha-fetoprotein screening test result, the nurse would discuss the need for:
A) Special care needed for a Down syndrome infant
B) A more specific determination of the acid–base status
C) Further, more definitive evaluations to conclude anything
D) Immediate termination of the pregnancy based on results
C
Feedback:
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 acid–base status of the fetus. Immediate termination is not warranted; more information is needed.
