Question 1
A client's chorionic villus sampling (CVS) reveals the presence of trisomy. How would the nurse interpret this test result?
◦ Nondisjunction has not occurred.
◦ The fetus's organ systems are involved.
◦ There is trisomy in the placenta.
◦ There is trisomy in at least one fetal tissue.
Question 2
A couple has experienced three spontaneous abortions (SABs) before week 9 of gestation and one SAB at week 20. What should the nurse consider when preparing to counsel this couple?
Select all that apply.
Note: Credit will be given only if all correct choices and no incorrect choices are selected.◦ The earlier the SAB, the more likely a rare genetic defect.
◦ Most SABs are related to genetic changes.
◦ Later-gestation SABs are more likely than early-gestation SABs to reflect genetic disorders that are seen in live newborns.
◦ If a genetic defect was present in the first SAB, it is more likely to be present in subsequent SABs.
◦ Trisomies, monosomy X, and polyploidy make up the majority of genetic abnormalities associated with SAB.
