1)
Which milestone is developmentally appropriate for a 2-month-old infant when the nurse pulls the infant to
a sitting position?
a. Head lag is present when the infants trunk is lifted.
b. The infant is able to support the head when the trunk is lifted.
c. The infant is briefly able to hold the head erect.
d. The infant is fully able to support and hold the head in a straight line.
CORRECT ANSWER: C
Rationale: A 2-month-old infant is able to hold the head erect only briefly and continues to have some
head lag. It is not until 4 months of age that the infant can keep his or her head in a straight line when
pulled to a sitting position.
2) Approximately what should a newborn weigh at 1 year of age if the newborns birth weight was 7
pounds 6 ounces?
a. 14 3/4 pounds
1/8
b. 22 pounds
c. 29 1/2 pounds
d. Unable to estimate weight at 1 year
CORRECT ANSWER: B
Rationale:An infant triples the birth weight by 1 year of age. An infant doubles the birth weight by 6
months of age. An infant quadruples the birth weight by 2 years of age. Weight at 6 months, 1 year, and 2
years of age can be estimated from the birth weight.
,3) Which statement made by a parent would be consistent with a developmental delay?
a. I have noticed that my 9-month-old infant responds consistently to the sound of his
name.
b. I have noticed that my 12-month-old child does not get herself to a sitting position
or pull to stand.
c. I am so happy when my 1 1/2-month-old infant smiles at me.
d. My 5-month-old infant is not rolling over in both directions yet.
CORRECT ANSWER: B
Rationale: Critical developmental milestones for gross motor development in a 12 month old include
standing briefly without support, getting to a sitting position, and pulling to stand. If a 12-month- old child
does not perform these activities, it may be indicative of a developmental delay. An infant who responds to
his name at 9 months of age is demonstrating abilities to both hear and interpret sound. A social smile is
present by 2 months of age. Rolling over in both directions is not a critical milestone for gross motor
development until the child reaches 6 months of age.
4) At a healthy 2-month-old infants well-child clinic visit, the nurse should give which
immunizations?
a. Dtap, IPV, hepb, Hib, PCV, rotavirus
b. MMR, dtap, PVC, and IPV
c. Hib, dtap, rotavirus, and OPV
d. Hib and MMR, IPV, and rotavirus
CORRECT ANSWER: A
Rationale: Dtap, IPV, hepb, Hib, PCV, and rotavirus are the appropriate sequence of immunizations for
a healthy 2-month-old infant. MMR is given at or after 12 months of age. Oral polio vaccine (OPV) is no
longer administered in the U.S.
5) The nurse advises the mother of a 3-month-old infant, exclusively breast-fed, to:
a. Start giving the infant a vitamin D supplement.
, b. Start using an infant feeder and add rice cereal to the formula.
c. Start feeding the infant rice cereal with a spoon at the evening feeding.
d. Continue breast-feeding without any supplements.
CORRECT ANSWER: A
Rationale: Breast milk does not provide an adequate amount of dietary vitamin D. Infants who are
exclusively breast-fed need vitamin D supplements to prevent rickets. An infant feeder is an inappropriate
method of providing the infant with caloric intake. Solid foods and rice cereal are not recommended for a
3-month-old infant. Solid feedings do not typically begin before 4 to 6 months of age. Because breast milk
is not an adequate source of fluoride, infants need to be given a fluoride supplement.
6) At months of age, an infant should first be expected to locate an object hidden from view.
a. 4
b. 6
c. 9
d. 20
CORRECT ANSWER: C
Rationale: By 9 months of age an infant will actively search for an object that is out of sight. Four-month-
old infants are not cognitively capable of searching out objects hidden from their view. Infants at this
developmental level do not pursue hidden objects. Six-month-old infants have not developed the ability to
perceive objects as permanent and do not search out objects hidden from their view. Twenty-month-old
infants actively pursue objects not in their view and are capable of recalling the location of an object not in
their view. They first look for hidden objects around the age of 9 months.
7) The parents of a newborn infant state, We will probably not have our baby immunized because we are
concerned about the risk of our child being injured. Which is the best response for the nurse to make?
