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.

Correct Answer is B
Explanation
A. Carrots are not a significant source of iron. They are rich in vitamins and fiber but do not contribute substantially to iron needs.
B. Chicken breast is a good source of heme iron, which is more readily absorbed by the body compared to non-heme iron found in plant foods. It helps meet the increased iron requirements during pregnancy.
C. Feta cheese is not a significant source of iron. It provides calcium and protein but does not contribute substantially to iron intake.
D. Apples are not a significant source of iron. While they are nutritious, they do not help meet the increased iron requirements during pregnancy.
Correct Answer is C
Explanation
A. Beginning each feeding with the same breast as the previous feeding is not necessary for effective breastfeeding. It is recommended to allow the newborn to fully drain the first breast before switching to the other side to ensure they receive both foremilk and hindmilk.
B. Newborns do not need additional water. Breast milk or formula provides all the hydration and nutrients a newborn requires, and offering water can interfere with the newborn’s intake of essential nutrients and calories.
C. Allowing the newborn to empty the first breast before switching sides ensures they receive the complete range of milk, including both foremilk and hindmilk, which supports optimal growth and satisfaction.
D. Providing a formula supplement is not typically necessary unless specifically indicated for medical reasons. Exclusive breastfeeding is recommended for the first six months of life, and formula should not be introduced without cause.
