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 C

Explanation

Choice A rationale

Starting each feeding with the same breast can lead to engorgement and decreased milk supply in the other breast.

Choice B rationale

Exclusive breastfeeding is recommended for the first six months. Providing a formula supplement can interfere with milk supply and breastfeeding success.

Choice C rationale

Allowing the newborn to empty the first breast ensures they receive hindmilk, which is richer in fat and essential for growth.

Choice D rationale

Newborns do not need additional water as breast milk or formula provides all necessary hydration.

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.
