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.

Explanation
- Encourage frequent ambulation: Anticipated. Ambulation can help progress labor, unless contraindicated by the healthcare provider.
- Prepare the client for catheterization: Non-essential. There is no current indication for catheterization as the client is voiding adequately and not in active labor.
- Ensure the client maintains a supine position while in bed: Contraindicated. The supine position can cause supine hypotensive syndrome in pregnant clients. A side-lying position is preferred to optimize blood flow.
- Check FHR every 30 min: Anticipated. Regular monitoring of FHR is important to assess fetal well-being during labor.
- Perform a Nitrazine test: Anticipated. Since the client reports fluid leakage, a Nitrazine test can help confirm if the membranes have ruptured.
- Check client's temperature every hour: Non-essential. The client's temperature is stable, and hourly checks are not indicated unless there are signs of infection or the membrane has been ruptured for an extended period.
- Obtain CBC blood sample: Anticipated. A CBC can help identify any underlying issues such as anemia or infection that could affect labor and delivery.
Correct Answer is D
Explanation
A. Wear the lap belt high across the abdomen is incorrect. The lap belt should be worn low across the pelvis, not high across the abdomen, to avoid injury in the event of a collision.
B. Place the shoulder harness across the gravid uterus is incorrect. The shoulder harness should be placed across the chest and between the breasts, not directly across the uterus, to ensure safety.
C. Disable the vehicle's driver-side airbags is incorrect. Airbags should not be disabled, as they are crucial for safety. The seat should be adjusted to a safe distance from the steering wheel to avoid potential injury from the airbag.
D. Move the seat as far away as possible from the steering wheel is correct. This adjustment ensures that the driver is positioned safely away from the steering wheel and airbag, reducing the risk of injury during a collision.
