Question 2

Nurses should be aware of the strengths and limitations of various biochemical assessments during pregnancy, including that
 
  a. Chorionic villus sampling (CVS) is becoming more popular because it provides
  early diagnosis.
  b. Screening for maternal serum alpha-fetoprotein (MSAFP) levels is recommended
  between 10 and 12 weeks of gestation in order to give parents time to consider
  options.
  c. Percutaneous umbilical blood sampling (PUBS) is one of the multiple marker
  screen tests for Down syndrome.

A CVS does provide a rapid result, but it is declining in popularity because of
advances in noninvasive screening techniques.
B MSAFP screening is recommended for all pregnant women.
