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. Placing a rolled blanket behind the newborn’s neck is unsafe and can cause improper positioning in the car seat. The newborn should be positioned properly according to the car seat manufacturer's instructions to ensure safety during travel.
B. The car seat should be positioned at a 45° angle to keep the newborn’s airway open and prevent slumping. This angle supports proper head and neck alignment, which is essential for the baby’s safety and comfort during travel.
C. The retainer clip should be positioned at the level of the newborn’s armpits, not the umbilicus. Proper placement of the retainer clip ensures that the harness is secure and correctly positioned over the baby’s shoulders.
D. Newborns should be placed in a rear-facing position in the car seat for optimal safety. Forward-facing car seats are used later, but infants should always be in a rear-facing car seat until they meet the age, weight, and height requirements for transitioning.
Correct Answer is B
Explanation
A. A client whose newborn is having difficulty latching-on should be addressed, but this issue is not an immediate postpartum emergency. It is important but does not require urgent intervention compared to potential complications from magnesium sulfate.
B. A client who received magnesium sulfate during labor should be seen first because magnesium sulfate can cause significant side effects like respiratory depression, decreased reflexes, and altered mental status. These effects require close monitoring to prevent severe complications.
C. A client who has a history of oligohydramnios requires monitoring but this history does not necessarily indicate an immediate postpartum issue requiring urgent assessment at this time.
D. A client whose labor lasted for 6 hr does not have an immediate concern solely based on labor duration. While it is relevant, it does not indicate an urgent need for assessment compared to the effects of magnesium sulfate.
