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 can indicate a genetic disorder.
This test determines how well my placenta is functioning.
This test is done if there is a risk of an Rh incompatibility.
The results will show if my baby's lungs are mature.
The Correct Answer is D
Choice A rationale
Lecithin/sphingomyelin (L/S) ratio does not indicate genetic disorders; it's used to assess fetal lung maturity.
Choice B rationale
The test does not determine placental function. It specifically evaluates fetal lung maturity through the ratio of lecithin to sphingomyelin in amniotic fluid.
Choice C rationale
The test is not used to assess the risk of Rh incompatibility. The L/S ratio focuses on lung development rather than blood compatibility issues.
Choice D rationale
The L/S ratio assesses the baby's lung maturity, indicating if the lungs produce enough surfactant for proper function after birth.

Correct Answer is A
Explanation
Choice A rationale
A single crease in the palm, known as a simian crease, is a common characteristic seen in infants with trisomy 21 (Down syndrome) due to the unique hand structure associated with this condition.
Choice B rationale
A notch in the lip, such as a cleft lip, is not commonly associated with trisomy 21 and is more typically related to other genetic conditions or environmental factors during development.
Choice C rationale
An inversion of the foot, such as clubfoot, is not a specific characteristic of trisomy 21. This condition is more often seen in other congenital anomalies not related to Down syndrome.
Choice D rationale
Extra digits on the hand, or polydactyly, is not commonly associated with trisomy 21 but can be seen in other genetic disorders. Trisomy 21 has more specific physical features like the simian crease.
Correct Answer is A
Explanation
Choice A rationale
Positioning the newborn's car seat at a 45° angle helps to maintain an open airway and reduces the risk of the baby's head falling forward, which can obstruct breathing.
Choice B rationale
Placing the car seat in a forward-facing position is incorrect for a newborn. Newborns and infants should always be placed in a rear-facing car seat to protect their head, neck, and spine in the event of a crash.
Choice C rationale
Placing a rolled blanket behind the newborn's neck is not recommended as it can alter the position of the head and neck, potentially compromising the airway. Proper positioning is crucial to ensure safety and comfort.
Choice D rationale
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 reduces the risk of injury in a collision.
