This comprehensive 400-question test bank has been developed to mirror the structure, cognitive complexity, and clinical
reasoning demands of the ATI RN Pediatric Nursing Edition 12.0 Content Mastery Series and the corresponding proctored
examination. Each item has been constructed using the ATI-style test blueprint, with distractors designed to reflect the
most common pediatric nursing pitfalls: applying adult norms to children, misidentifying developmental expectations,
incorrect weight-based dosing, confusing croup with epiglottitis, missing dehydration signs, failing to recognize
child-abuse indicators, and improper isolation precautions. Rationales integrate age-specific considerations, developmental
theory, safety principles, family-centered care, and explicit chapter mapping for targeted remediation. Use this bank for
spaced review, remediation, and proctored-exam readiness.
EXAM INSTRUCTIONS: Select the ONE best answer for each question. Rationales appear immediately below each item,
followed by chapter mapping for targeted review and clinical-judgment development.
SECTION 1: Growth, Development, and Health Promotion (Ch. 1–4: Developmental
Milestones, Immunizations, Nutrition, & Health Screening) — Questions Q1–Q42
Q1: A mother brings her 2-month-old infant to the well-child clinic. Which motor milestone should
the nurse EXPECT to be present at this age?
A. Sits without support
B. Holds head steady when pulled to sitting [CORRECT]
C. Rolls from abdomen to back
D. Crawls on hands and knees
Correct Answer: B
Rationale: By 2 months, infants can briefly hold their head erect when pulled to sitting and lift the chest slightly
during tummy time. Sitting without support emerges at 6–8 months, rolling abdomen-to-back around 4–6 months, and
crawling around 9 months. Selecting older-age milestones would falsely reassure the caregiver and could delay
recognition of true developmental delay.

Q2: During a well-child visit, the parents of a 12-month-old ask which milestone is EXPECTED. The
nurse should identify which finding as typical for this age?
A. Walks holding onto furniture (cruising) [CORRECT]
B. Uses two-word phrases consistently
C. Climbs stairs with alternating feet
D. Copies a circle on paper
Correct Answer: A
Rationale: At 12 months, most infants pull to stand and cruise along furniture; independent walking often emerges
between 12 and 15 months. Two-word phrases develop around 24 months, alternating-foot stair climbing around 4
years, and copying a circle around 3 years. Applying toddler or preschool norms to an infant would distort
anticipatory guidance.
Chapter Mapping: Ch. 1 — Growth & Development: Infancy & Toddler Transition
Q3: A nurse is teaching anticipatory guidance to the parents of a 2-month-old infant. Which
statement by the parent indicates teaching has been EFFECTIVE?
A. "I will place my baby on the stomach to sleep."
B. "I will offer rice cereal in the bottle at bedtime."
C. "I will alternate the direction my baby's head faces in the crib." [CORRECT]
D. "I will keep soft pillows and bumpers in the crib for comfort."
Correct Answer: C
Rationale: Alternating head position helps prevent positional plagiocephaly and is consistent with safe-sleep
anticipatory guidance. Infants must be placed supine on a firm, bare surface without pillows, bumpers, or soft objects,
and cereal should not be added to bottles before 4 to 6 months. The other options reflect outdated or unsafe practices
that increase sudden infant death syndrome (SIDS) and choking risk.

Q4: The parent of a 6-month-old asks when the first dental visit should occur. The nurse's BEST
response is:
A. "Schedule the first dental visit when the child turns 3 years old."
B. "The first dental visit should occur within 6 months of the first tooth eruption, or by age 12
months at the latest." [CORRECT]
C. "Dental visits are not necessary until all primary teeth have erupted."
D. "Bring the child to the dentist only if tooth pain develops."
Correct Answer: B
Rationale: The American Academy of Pediatric Dentistry and the American Academy of Pediatrics recommend the
first dental visit within 6 months of the first tooth erupting or by 12 months of age, whichever comes first. Delaying
dental assessment until age 3 or until pain develops misses the window for early caries prevention, fluoride
counseling, and establishing a dental home.

Q5: Which gross motor skill is EXPECTED of a typically developing 18-month-old toddler?
A. Rides a tricycle
B. Jumps in place with both feet
C. Walks up stairs with one hand held [CORRECT]
D. Stands on one foot for 5 seconds
Correct Answer: C
Rationale: An 18-month-old can typically walk independently, climb stairs with one hand held, and squat to play.
Riding a tricycle is a 3-year skill, jumping in place with both feet emerges around 24 months, and standing on one
foot for several seconds is a 4-year skill. Choosing older-age milestones would overestimate the toddler's balance and
coordination capacity.
Chapter Mapping: Ch. 1 — Growth & Development: Toddler
Q6: A nurse is assessing a 4-year-old child's developmental status. Which finding requires
IMMEDIATE follow-up?
A. The child uses 5- to 6-word sentences.
B. The child cannot hop on one foot.
C. The child is not yet toilet trained for nighttime.
D. The child's speech is largely unintelligible to strangers. [CORRECT]
Correct Answer: D
Rationale: By age 4, a child's speech should be 100% intelligible to strangers, even those unfamiliar with the child.
Unintelligible speech at this age strongly suggests a hearing deficit, articulation disorder, or developmental language
delay and warrants immediate referral. Five- to six-word sentences are age-appropriate, hopping on one foot
emerges closer to age 5, and nighttime dryness often lags daytime training.

Q7: According to Erikson, the developmental task of a toddler (1–3 years) is which of the
following?
A. Trust versus mistrust
B. Autonomy versus shame and doubt [CORRECT]
C. Initiative versus guilt
D. Industry versus inferiority
Correct Answer: B
Rationale: Erikson identifies the toddler stage as autonomy versus shame and doubt, in which the child asserts
independence through choices such as dressing, feeding, and toileting. Trust versus mistrust characterizes infancy,
initiative versus guilt the preschool years, and industry versus inferiority the school-age years. Misapplying Erikson's
stages would distort the nurse's guidance on supporting independence.

Q8: A nurse is providing anticipatory guidance to the parents of a 3-year-old. Which parental
statement indicates an understanding of preschool cognitive development per Piaget?
A. "My child understands that other people see things differently than he does."
B. "My child believes the moon follows him when we walk at night." [CORRECT]
C. "My child can classify objects by color and shape simultaneously."
D. "My child uses logical reasoning to solve problems."
Correct Answer: B
Rationale: Piaget describes the preschool years (ages 2–7) as the preoperational stage, marked by egocentrism and
magical thinking—the child believes the moon follows him. Concrete classification and logical reasoning emerge in
the concrete operational stage (7–11 years), and theory of mind (understanding others' perspectives) develops
gradually but is not yet stable in a 3-year-old.
Chapter Mapping: Ch. 1 — Cognitive Development: Piaget Preoperational Stage
Q9: An adolescent tells the school nurse, "My parents don't understand me, and my friends are the
only ones who get it." This statement is most consistent with which aspect of adolescent
psychosocial development?
A. Industry versus inferiority
B. Identity versus role confusion [CORRECT]
C. Trust versus mistrust
D. Intimacy versus isolation
Correct Answer: B
Rationale: Erikson's adolescent task is identity versus role confusion, during which peers become central as the
adolescent experiments with values, beliefs, and roles separate from parents. The shift toward peers is
developmentally expected, not pathological. Industry is the school-age task, intimacy a young-adult task, and trust the
infancy task.

Q10: A nurse is teaching parents about car seat safety for their 9-month-old infant who weighs 18
lb (8.2 kg). Which instruction is CORRECT per current AAP guidelines?
A. The infant may transition to a forward-facing car seat now.
B. The infant should remain in a rear-facing car seat until at least age 2 years. [CORRECT]
C. A booster seat is appropriate once the infant can sit unsupported.
D. The infant may ride in the front seat if the airbag is turned off.
Correct Answer: B
Rationale: The American Academy of Pediatrics recommends infants and toddlers remain rear-facing until they
reach the manufacturer's weight or height limit for the seat, which is typically beyond age 2. Forward-facing seats
come later, booster seats much later (typically age 4+), and children younger than 13 must never ride in the front seat
due to airbag injury risk.
