Which of the following symptoms should the nurse recognize as a manifestation of neonatal abstinence syndrome?
Weak cry.
Decreased muscle tone.
Exaggerated Moro reflex.
Consoles easily.
The Correct Answer is C
Choice A rationale
A weak cry is not a typical manifestation of neonatal abstinence syndrome (NAS). NAS usually presents with a high-pitched, persistent cry due to central nervous system irritability.
Choice B rationale
Decreased muscle tone is not common in NAS. Infants with NAS often exhibit hypertonia, characterized by increased muscle tone and rigidity.
Choice C rationale
This statement is correct because an exaggerated Moro reflex is a common sign of NAS, indicating central nervous system hyperactivity in response to withdrawal from maternal drugs.
Choice D rationale
An infant with NAS does not console easily. They are often difficult to soothe due to irritability and discomfort from withdrawal symptoms. .

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 D
Explanation
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.
