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?

A.

The results can indicate a genetic disorder.

B.

This test determines how well my placenta is functioning.

C.

This test is done if there is a risk of an Rh incompatibility.

D.

The results will show if my baby's lungs are mature.

Answer and Explanation

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

"Decreased BP.”. This is correct because hyperemesis gravidarum can lead to dehydration, which in turn can cause hypotension (decreased blood pressure).

Choice B rationale

"WBC count 15,000/mm³ (5,000 to 15,000/mm³).”. This is incorrect because while WBC count can be elevated due to stress or infection, it is not a primary manifestation of hyperemesis gravidarum.

Choice C rationale

"Pruritus.”. This is incorrect because pruritus is not commonly associated with hyperemesis gravidarum. It is more likely related to other conditions like cholestasis of pregnancy.

Choice D rationale

"Hemoglobin 18 g/dL (11 to 16 g/dL).”. This is incorrect because an elevated hemoglobin level is not a direct manifestation of hyperemesis gravidarum, although dehydration can potentially concentrate blood components and slightly elevate hemoglobin.

Correct Answer is B

Explanation

Choice A rationale

Elevating the client's legs is incorrect as an initial intervention. It is more important to address the potential cause of the late decelerations first.

Choice B rationale

Turning the client onto their side is correct. This intervention can improve blood flow to the fetus and reduce the pressure on the vena cava, potentially alleviating late decelerations.

Choice C rationale

Palpating the client's uterus is not the first action. It is essential to address maternal positioning and oxygenation issues first.

Choice D rationale

Increasing the client's IV fluid infusion rate may help, but it is not the initial action. Positioning changes can have an immediate effect on fetal oxygenation.
