Chorionic Villus Sampling (CVS)
Chorionic Villus Sampling (CVS) ( 5 Questions)
A nurse is caring for a client who is scheduled for chorionic villus sampling (CVS).
Which of the following statements should the nurse include in the teaching?
This is because chorionic villus sampling (CVS) involves taking a small sample of tissue from the placenta, which may cause some discomfort and bleeding.
You may not experience leaking of amniotic fluid after the procedure. CVS does not involve puncturing the amniotic sac, unlike amniocentesis.
You may not experience Rh sensitization after the procedure. Rh sensitization is a condition where the mother’s immune system attacks the baby’s blood cells if they have different Rh factors. CVS can prevent this by testing the baby’s blood type and giving an injection of anti-D immunoglobulin to the mother if needed.
You may not experience neural tube defects after the procedure. Neural tube defects are birth defects that affect the brain and spinal cord of the baby. CVS cannot detect these conditions, but amniocentesis can. Therefore, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.
