A nurse is reinforcing teaching with a client who is undergoing amniotic fluid assessment for the lecithin/sphingomyelin ratio. Which of the following client statements indicates an understanding of the teaching?
"The results will show if my baby's lungs are mature."
"This test determines how well my placenta is functioning."
"This test is done if there is a risk of an Rh incompatibility."
"The results can indicate a genetic disorder."
The Correct Answer is A
A. The lecithin/sphingomyelin (L/S) ratio assesses fetal lung maturity. A higher ratio indicates that the baby's lungs are mature enough to handle breathing air outside the womb, which is the primary purpose of this test.
B. The L/S ratio test does not assess placental function. Placental function is evaluated through other tests, such as Doppler studies or biophysical profiles.
C. The L/S ratio test is not related to Rh incompatibility. Rh incompatibility issues are managed through different assessments, such as the Coombs test and Rh factor screening.
D. The L/S ratio test does not indicate genetic disorders. Genetic disorders are assessed through tests like amniocentesis or chorionic villus sampling, not the L/S ratio.
