When assessing a newborn, which is the best method for the nurse to use to elicit the Moro reflex?
Making a loud sound within close range of the newborn.
Firmly stroking the soles of the newborn’s feet with a thumb nail.
Using the newborn’s hands to raise the baby from a supine position without supporting the head.
Holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface.
The Correct Answer is A
The correct answer is choice A. Making a loud sound within close range of the newborn will elicit the Moro reflex, which is an involuntary protective motor response against abrupt disruption of body balance or extremely sudden stimulation. The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually).
Choice B is wrong because firmly stroking the soles of the newborn’s feet with a thumb nail will elicit the Babinski reflex, which is a normal response in infants that involves fanning out and curling of the toes.
Choice C is wrong because using the newborn’s hands to raise the baby from a supine position without supporting the head will elicit the traction response, which is a normal response in infants that involves flexion of the elbows and shoulders.
Choice D is wrong because holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface will elicit the stepping reflex, which is a normal response in infants that involves alternating steps with each foot.

Correct Answer is A
Explanation
The correct answer is choice A. A breastfed baby is likely to gain weight more rapidly in the first month of life.This statement is wrong because breastfed babies generally gain weight faster than formula-fed babies for the first 3 months of life.They also double their birth weight by 3-4 months and triple it by one year.
Therefore, a breastfed baby’s weight gain in the first month of life is not unusual or concerning.
Choice B is correct because breastfeeding is not a reliable method of birth control.A woman can still ovulate and become pregnant while breastfeeding, especially if she feeds her baby less frequently or supplements with formula or solids.
Choice C is correct because breastfeeding has been shown to reduce the risk of allergies in babies.Breast milk contains antibodies and other immune factors that protect the baby from infections and allergic reactions.
Choice D is correct because breastfeeding mothers need to drink enough fluids to stay hydrated and produce enough milk.The recommended fluid intake for breastfeeding mothers is about 13 cups (3 liters) per day.
Correct Answer is D
Explanation
The correct answer is choice D: “This test is used to identify fetal abnormalities.” Alpha-fetoprotein (AFP) is a protein produced by the fetus that can be measured in the mother’s blood.
Abnormal levels of AFP may indicate a problem with the development of the baby’s brain, spine, or other organs.
This test is usually done between 15 and 20 weeks of gestation.
Choice A is wrong because AFP does not measure the baby’s maturity.
It is not related to the gestational age or the lung development of the fetus.
Choice B is wrong because AFP is not a routine test for all pregnant women over thirty years of age.
It is an optional screening test that may be offered to women who have a higher risk of having a baby with a birth defect, such as those who have a family history, a previous affected pregnancy, or certain ethnic backgrounds.
Choice C is wrong because AFP is not recommended for people with a history of infertility.
It does not assess the fertility status of the mother or the father.
It only measures the level of a fetal protein in the mother’s blood.
