ATI PEDIATRICS NURSING EXAM 2026/2027
Exam Questions and Verified Answers with Detailed Rationales
DOCUMENT OVERVIEW
• This comprehensive 200-question exam is designed to strengthen your
understanding of pediatric nursing principles, clinical assessments, and
interventions across all major pediatric conditions and developmental stages—use
this material to identify knowledge gaps, practice test-taking strategies, and build
confidence for high-stakes exams.
• Study features include detailed rationales for every question to deepen
conceptual understanding, answer explanations that reinforce critical thinking, and
comprehensive topic coverage from newborn to adolescent populations to ensure
mastery of the entire pediatric nursing scope.
GROWTH AND DEVELOPMENT (Questions 1-15)
Question 1: A nurse is assessing a 6-month-old infant during a well-baby visit.
Which of the following developmental milestones should the nurse expect to
observe?
A) The infant can roll from back to stomach
B) The infant can sit without support for more than a few seconds
C) The infant can grasp objects with a raking grasp
D) The infant can pull to a standing position using furniture
E) The infant can walk with minimal assistance
CORRECT ANSWER: C) The infant can grasp objects with a raking grasp
,Rationale: At 6 months of age, infants develop a raking grasp, which is an ulnar
palmar grasp pattern. Rolling from back to stomach typically occurs at 8 months.
Sitting without support develops around 8-9 months. Pulling to stand with furniture
support occurs around 9-10 months. Independent walking with minimal assistance
is a 12-15 month milestone. The raking grasp at 6 months is the most accurate
milestone for this age.
Question 2: A nurse is reviewing the developmental milestones for a 12-month-old
toddler. Which behavior indicates the child is meeting expected milestones?
A) Speaking in complete sentences with correct grammar
B) Using a pincer grasp and beginning to cruise along furniture
C) Riding a tricycle independently
D) Playing complex imaginative games with other children
E) Tying shoelaces with accuracy
CORRECT ANSWER: B) Using a pincer grasp and beginning to cruise along
furniture
Rationale: At 12 months, children develop a superior pincer grasp (thumb and
index finger) and begin cruising along furniture as they prepare for walking.
Speaking in complete sentences is a 3-4 year milestone. Independent tricycle riding
occurs around 3 years. Complex imaginative group play develops around 4-5 years.
Tying shoelaces is typically a 5-6 year skill. Pincer grasp and cruising are the
appropriate 12-month milestones.
Question 3: A 3-year-old child is displaying magical thinking and egocentrism
during play. According to Piaget's theory, which cognitive stage is this child in?
A) Sensorimotor stage
B) Preoperational stage
C) Concrete operational stage
,D) Formal operational stage
E) Abstract reasoning stage
CORRECT ANSWER: B) Preoperational stage
Rationale: The preoperational stage (ages 2-7 years) is characterized by magical
thinking, egocentrism, and symbolic play. Sensorimotor stage (0-2 years) involves
learning through senses and movement. Concrete operational stage (7-11 years)
involves logical thinking about concrete objects. Formal operational stage (11+
years) involves abstract thinking. The behaviors described are classic characteristics
of the preoperational stage.
Question 4: A mother reports that her 18-month-old toddler has a vocabulary of
approximately 10-15 words. The nurse should:
A) Recommend an immediate speech therapy evaluation
B) Explain that this is within normal developmental range
C) Refer the child to a developmental pediatrician
D) Suggest that the mother increase talking to the child dramatically
E) Schedule the child for a hearing assessment immediately
CORRECT ANSWER: B) Explain that this is within normal developmental range
Rationale: At 18 months, toddlers typically have a vocabulary of 10-50 words, with
an average of 10-15 words being completely normal. While language development
can be variable, this falls within normal limits and does not warrant immediate
referral. Suggesting speech therapy, developmental evaluation, or hearing tests
would be premature without other concerning signs. Parents should continue
normal language modeling, but no special intervention is needed at this stage.
Question 5: During a 2-year-old's assessment, the nurse observes the child playing
alongside other children but not interacting with them. The nurse recognizes this
as:
, A) Solitary play, which is abnormal for this age
B) Parallel play, which is normal for this age
C) Cooperative play, which indicates advanced development
D) Associative play, which occurs only in preschoolers
E) Competitive play, which is concerning
CORRECT ANSWER: B) Parallel play, which is normal for this age
Rationale: Parallel play (playing alongside but not with others) is the expected type
of play for toddlers aged 2-3 years. Solitary play is normal from infancy to age 2.
Associative play begins around age 3-4 years. Cooperative play with rules develops
around age 4-5 years. The observation of a 2-year-old engaging in parallel play is
completely developmentally appropriate and indicates normal social development.
Question 6: A 4-year-old child asks the nurse, "Why do I have to take this
medicine?" Which response best reflects Erikson's stage of development for this
age?
A) "Because I said so"
B) "To make you healthy and strong so you can play"
C) "You will understand when you are older"
D) "All children your age take medicine"
E) "It's very complicated; you wouldn't understand"
CORRECT ANSWER: B) "To make you healthy and strong so you can play"
Rationale: A 4-year-old is in Erikson's Initiative vs. Guilt stage and understands
concrete explanations related to their activities and interests. Using simple
language that connects to their play and activities (things they value) helps them
understand while supporting their sense of initiative. Dismissive answers don't
respect their developmental stage. Complex medical explanations are beyond their
comprehension. Connecting the medication to their ability to play respects their
developing autonomy.
