A nurse is reinforcing teaching with a client who is at 35 weeks of gestation and has a prescription for a lecithin/sphingomyelin ratio. Which of the following statements should the nurse make?
"This test will detect possible birth defects."
"This test will reveal the sex of the fetus."
"This test will identify your risk for preterm labor."
"This test will determine fetal lung maturity."
The Correct Answer is D
A. The lecithin/sphingomyelin (L/S) ratio test is not used to detect birth defects. It specifically assesses fetal lung maturity by measuring the ratio of two phospholipids present in fetal lung surfactant.
B. The L/S ratio test does not reveal the sex of the fetus. It is unrelated to fetal gender determination.
C. While preterm labor risk can be assessed through other methods, such as cervical length
measurement or fetal fibronectin testing, the L/S ratio test is specifically focused on fetal lung maturity.
D. The L/S ratio test is primarily used to determine fetal lung maturity, as an increased ratio indicates lung maturity and readiness for extrauterine life.
