  1. because of new imaging techniques, it is now possible in the first trimester.
  2. despite the use of ultrasonography, complications still occur in the mother or in-fant in 5 to 10 of cases.
  3. the shake test or bubble stability test is a quick means of determining fetal matur-ity.
  4. the presence of meconium in the amniotic fluid is always cause for concern.

Answer to Question 1

1. Incorrect. Amniocentesis is possible after the 14th week of pregnancy, when the uterus becomes an abdominal organ.

2. Correct. This couple already has a child with a genetic disease and will be given a re-currence risk.
3. Incorrect. Predictive testing is used to clarify the genetic status of an asymptomatic fami-ly member.
