A client at 8 weeks' gestation has been advised to have the embryo undergo genetic testing. The nurse will instruct the client that the area of the embryo being tested will be the:
1. Endometrium.
2. Ectoderm.
3. Chorion.
4. Amnion.
3. Chorion.
Rationale:
The chorion is the outermost embryonic membrane and develops into chorionic villi, which can be used for early genetic testing of the embryo at 8 to 11 weeks' gestation by chorionic villi sampling. The endometrium is the lining of the uterus and will not be used for genetic testing of the embryo. The ectoderm is a germ layer and will develop into specific structures within the developing fetus. The amnion will develop into amniotic fluid, which can also be sampled for genetic testing but may not be developed by 8 weeks; gestation.
