A nurse is assessing the reflexes of a term newborn. After placing the newborn in the supine position, which of the following methods should the nurse use to elicit the Moro reflex?
Make a loud noise above the newborn.
Touch the newborn's cheek with a finger.
Tap the newborn's forehead with a finger.
Turn the newborn's head to one side.
The Correct Answer is A
Choice A rationale:
The Moro reflex, also known as the startle reflex, is elicited by making a loud noise above the newborn, causing them to extend their arms and legs and then bringing them back to the body in a hugging motion. This reflex is a normal developmental response in term newborns.
Choice B rationale:
Touching the newborn's cheek with a finger elicits the rooting reflex, where the newborn turns their head toward the stimulus, searching for a nipple or object to suck. It is a different reflex and not the Moro reflex.
Choice C rationale:
Tapping the newborn's forehead with a finger does not elicit any specific reflex. This action is not related to the Moro reflex.
Choice D rationale:
Turning the newborn's head to one side elicits the asymmetric tonic neck reflex (ATNR), not the Moro reflex. In ATNR, when the head is turned to one side, the arm on that side extends while the opposite arm flexes.

Correct Answer is B
Explanation
Choice A rationale:
Hct (hematocrit) of 34% is a normal finding during pregnancy. Normal ranges vary during pregnancy, but generally, a hematocrit between 33% to 45% is considered normal during the second trimester.
Choice B rationale:
BUN (blood urea nitrogen) of 25 mg/dL should be reported to the provider. BUN measures kidney function, and during pregnancy, values above 20 mg/dL may indicate possible impaired kidney function, which requires further evaluation.
Choice C rationale:
Platelets of 170,000/mm³ are within the normal range during pregnancy. The normal platelet count during pregnancy is typically between 150,000 to 400,000/mm³.
Choice D rationale:
HbA1c (glycated hemoglobin) of 6% is a good indicator of blood sugar control and is within the target range for a pregnant woman with diabetes. The target HbA1c level for pregnant women with diabetes is usually around 6% or lower.
Correct Answer is C
Explanation
Choice A rationale:
Limiting the length of breastfeeding to 5 minutes per breast may not address the underlying issue of sore nipples and can compromise the newborn's nutritional intake and bonding with the mother.
Choice B rationale:
Offering supplemental formula between feedings is not indicated unless there are specific concerns about the newborn's weight gain or nutritional needs. It does not directly address the issue of sore nipples.
Choice C rationale:
Assessing the newborn's latch while breastfeeding is essential to identify if improper latch or positioning is causing sore nipples. Correcting the latch technique can alleviate the discomfort and promote effective breastfeeding.
Choice D rationale:
Instructing the client to wait 4 hours between daytime feedings may lead to inadequate feeding for the newborn, especially during the early postpartum period when frequent feedings are essential for establishing breastfeeding and ensuring proper milk supply.
