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 D

Explanation

Choice A rationale

Mongolian spots are common, benign skin markings that some newborns have, but they are not related to rubella exposure during pregnancy.

Choice B rationale

Jaundice is a common condition in newborns, characterized by a yellowing of the skin and eyes, usually due to an immature liver. It's not specifically linked to maternal rubella exposure.

Choice C rationale

Transient strabismus, or temporary misalignment of the eyes, can occur in newborns but is unrelated to rubella. It usually resolves on its own as the newborn's muscles develop.

Choice D rationale

Deafness is a significant risk associated with congenital rubella syndrome. Rubella can damage the developing auditory system in utero, leading to permanent hearing loss in the newborn.

Correct Answer is C

Explanation

Choice A rationale

The newborn's legs flexing at the knees and hips when pressure is applied to the soles indicates the stepping reflex, an expected response.

Choice B rationale

Newborns do not typically keep their eyes closed when tapped on the forehead; this is not an expected reflex response.

Choice C rationale

The palmar grasp reflex, where the newborn's fingers curl around the nurse's finger, is an expected and normal finding in newborns, indicating healthy neurological function.

Choice D rationale

The rooting reflex, where the newborn turns their head when their cheek is touched, is expected and demonstrates feeding readiness and normal neural development. .
