1. The nurse is examining a 10-month-old boy who was born 10 weeks early. Which
finding is cause for concern? A) The child has doubled his birth weight.
B) The child exhibits plantar grasp reflex.
C) The child's head circumference is 19.5 inches.
D) No primary teeth have erupted yet.
Answer: Ans: C
Feedback: The child's head size is large for his adjusted age (7.5 months), which
would be cause for concern. Birth weight doubles by about 4 months of age. Plantar
grasp reflex does not disappear until 9 months adjusted age. Primary teeth may not
erupt until 8 months adjusted age.
2. The nurse is teaching a new mother about the drastic growth and developmental
changes her infant will experience in the first year of life. Which statement describes
a developmental milestone occurring in infancy?
A) By 6 months of age the infant's brain weighs half that of the adult brain; at age 12
months, the brain weighs 2.5 times what it did at birth.
B) Most infants triple their birthweight by 4 to 6 months of age and quadruple their
birthweight by the time they are 1 year old.
C) The head circumference increases rapidly during the first 6 months: the average
increase is about 1 inch per month.
D) The heart triples in size over the first year of life; the average pulse rate decreases
from 120 to 140 in the newborn to about 100 in the 1-year-old.
Answer: Ans: A
Feedback: By 6 months of age the infant's brain weighs half that of the adult brain; at
age 12 months, the brain weighs 2.5 times what it did at birth. Most infants double
their birthweight by 4 to 6 months of age and triple their birthweight by the time
they are 1 year old. The head circumference increases rapidly during the first 6
months: the average increase is about 0.6 inch (1.5 cm) per month. The heart doubles

in size over the first year of life. As the cardiovascular system matures, the average
pulse rate decreases from 120 to 140 in the newborn to about 100 in the 1-year-old.
3. The nurse is assessing the respiratory system of a newborn. Which anatomic
differences place the infant at risk for respiratory compromise? Select all that apply.
A) The nasal passages are narrower.
B) The trachea and chest wall are less compliant.
C) The bronchi and bronchioles are shorter and wider.
D) The larynx is more funnel shaped.
E) The tongue is smaller.
F) There are significantly fewer alveoli.
Answer: Ans: A, D, F
Feedback: In comparison with the adult, in the infant, the nasal passages are
narrower, the trachea and chest wall are more compliant, the bronchi and
bronchioles are shorter and narrower, the larynx is more funnel shaped, the tongue
is larger, and there are significantly fewer alveoli. These anatomic differences place
the infant at higher risk for respiratory compromise. The respiratory system does not
reach adult levels of maturity until about 7 years of age
4. A new mother shows the nurse that her baby grasps her finger when she touches
the baby's palm. How might the nurse respond to this information?
A) 'This is a primitive reflex known as the plantar grasp.'
B) 'This is a primitive reflex known as the palmar grasp.'
C) 'This is a protective reflex known as rooting.'
D) 'This is a protective reflex known as the Moro reflex.'
Answer: Ans: B
Feedback: Primitive reflexes are subcortical and involve a whole-body response.
Selected primitive reflexes present at birth include Moro, root, suck, asymmetric
tonic neck, plantar and palmar grasp, step, and Babinski. During the palmar grasp,
the infant reflexively grasps when the palm is touched. The plantar grasp occurs
