ISPN考试模拟试题(130)

Question: 

A 40-year-old primigravid client with AB-positive blood visits the outpatient clinic for an amniocentesis at 16 weeks’ gestation. The nurse determines that the most likely reason for the client’s amniocentesis is todetermine if the fetus has which of the following?

1. Cri-du-chat syndrome.

2. ABO incompatibility.

3. Erythroblastosis fetalis.

4. Down syndrome.


Because of the client’s age, the amniocentesis is most likely being doneto evaluate for Down syndrome (trisomy 21). Women older than 35 years are at higher risk for having a child with Down syndrome. Cri-du-chat syndrome is a genetic disorder involving a short arm on chromosome 5. This disorder is not associated with mothers who are older than 35 years.
The client is AB-positive, so the amniocentesis is not being done for ABO incompatibility, in which the mother is type O and the fetus is type A, B, or AB. The amniocentesis is not being done to detect erythroblastosis fetalis because the mother is Rh-positive.

CN: Reduction of risk potential; CL: Analyze
Answer:4
小编寄语:胜利不是战胜敌人,而是提高自己。我们只要每天进步百分之一,那就是成功。
