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?
“The procedure is usually performed between 10 and 13 weeks of gestation.” This is because CVS can provide early diagnosis of chromosomal abnormalities and genetic disorders in the first trimester of pregnancy.
The procedure has a risk of miscarriage of about 0.5% to 1%. This is higher than the risk of amniocentesis, which is another prenatal diagnostic test.
The procedure has a risk of infection of about 0.5%. This is due to the insertion of a needle or a catheter through the abdomen or the cervix to obtain a sample of chorionic villi.
The procedure has a risk of bleeding of about 1% to 2%. This is caused by the disruption of blood vessels in the placenta during the sampling.
