ISPN考试模拟试题(八十一)

The physician prescribes a maternal blood test for alpha fetoprotein for a nulligravid client at 16 weeks’ gestation. When developing the teaching plan, the nurse bases the explanations on the understanding that this test is used to detect which of the following? 
1. Neural tube defects.

2. Chromosomal anomalies.

3. Inborn errors of metabolism.

4. Lecithin-sphingomyelin ratio.

Chorionic villi sampling is used to detect chromosomal anomalies. Amniotic fluid amino acid determination is used to detect inborn errors of metabolism such as phenylketonuria.
