1. A nurse is assessing a 4-month-old infant during a well-child visit. Which developmental milestone
should the nurse expect the infant to have achieved?
A) Sitting without support
B) Rolling from back to front
C) Holding the head steady when upright
D) Crawling on hands and knees
Correct Answer: Holding the head steady when upright
Rationale: By 4 months of age, infants typically can hold their head steady when upright. Sitting without
support is expected around 8 months, rolling from back to front around 6 months, and crawling around
8–10 months.
2. A mother asks the nurse when her infant will likely double their birth weight. Which response by the
nurse is most accurate?
A) "Most infants double their birth weight by 4 months."
B) "Most infants double their birth weight by 6 months."
C) "Most infants double their birth weight by 9 months."
D) "Most infants double their birth weight by 12 months."
Correct Answer: "Most infants double their birth weight by 6 months."
Rationale: Infants typically double their birth weight by 6 months of age and triple it by 12 months. This
is a key growth milestone used to assess adequate nutrition and development.
,3. A nurse is teaching a group of parents about developmental milestones. At what age should an infant
begin to sit without support?
A) 4 months
B) 6 months
C) 8 months
D) 10 months
Correct Answer: 8 months
Rationale: Most infants can sit unsupported by 8 months of age. This gross motor milestone requires
sufficient core muscle strength and coordination.
4. A 2-year-old toddler is able to perform which gross motor skill?
A) Ride a tricycle
B) Kick a ball forward
C) Hop on one foot
D) Walk up stairs with alternating feet
Correct Answer: Kick a ball forward
Rationale: Kicking a ball forward is a typical gross motor skill for a 2-year-old. Riding a tricycle is
expected around 3 years, hopping on one foot around 4 years, and walking up stairs with alternating
feet around 3 years.
5. A nurse is evaluating the fine motor skills of a toddler. Which task is developmentally appropriate for
a toddler?
A) Buttoning a shirt
B) Writing with a pencil
C) Holding a spoon to eat
D) Using a pincer grasp
, Correct Answer: Holding a spoon to eat
Rationale: Holding a spoon to eat is a typical fine motor skill for a toddler. Buttoning a shirt and writing
with a pencil are skills expected at older ages, while the pincer grasp develops in infancy.
6. A nurse is assessing a newborn's reflexes. Which finding is a normal primitive reflex that should be
present at birth?
A) Absent Moro reflex
B) Asymmetric tonic neck reflex
C) Positive Babinski reflex
D) Negative palmar grasp
Correct Answer: Positive Babinski reflex
Rationale: The Babinski reflex (toes fan outward when the sole is stroked) is a normal primitive reflex in
newborns and infants up to 12 months. Absent or asymmetric reflexes may indicate neurological issues.
7. An infant is learning about the world through their senses. According to Piaget, which developmental
stage is this infant in?
A) Sensorimotor stage
B) Preoperational stage
C) Concrete operational stage
D) Formal operational stage
Correct Answer: Sensorimotor stage
Rationale: According to Piaget, infants use their senses and motor abilities to learn and explore the
environment during the sensorimotor stage, which lasts from birth to approximately 2 years of age.
