SECTION 1 — Growth, Development, and Health Promotion
(Chapters 1–4)
Q1. A parent brings a 4-month-old infant to the well-child clinic. Which motor milestone should the nurse identify as
EXPECTED for this age?
A. Sits without support and rolls completely from abdomen to back
B. Grasps a rattle with both hands and brings objects to midline [CORRECT]
C. Creeps on hands and knees and pulls to a standing position
D. Walks independently and uses a pincer grasp to pick up cereal
Correct Answer: B. Grasps a rattle with both hands and brings objects to midline
Rationale: By 4 months, infants typically grasp objects with both hands, bring them to the midline, and may roll from
abdomen to back. Sitting without support emerges closer to 6–8 months, creeping at 9 months, and independent walking at
~12 months. Applying older-age milestones to a 4-month-old is a common ATI test pitfall (Ch. 1, Growth & Development).
Q2. During a well-child visit, the parents of a 6-month-old ask when solid foods should be introduced. Which response
by the nurse is MOST appropriate?
A. Begin rice cereal mixed with breast milk or formula, followed by pureed vegetables and fruits. [CORRECT]
B. Delay solids until 12 months to reduce the risk of food allergies.
C. Introduce whole cow's milk now to meet increasing calcium needs.
D. Offer honey and egg whites first to expose the infant to common allergens early.
Correct Answer: A. Begin rice cereal mixed with breast milk or formula, followed by pureed vegetables and
fruits.
Rationale: Single-grain iron-fortified rice cereal mixed with breast milk or formula is the recommended first solid food at ~6
months, followed by pureed vegetables then fruits. Cow's milk is delayed until 12 months (renal immaturity), and honey is
contraindicated before 12 months due to infant botulism risk (Ch. 3, Pediatric Nutrition).
Q3. Which immunization should the nurse administer to a 2-month-old infant during the well-child visit according to
the 2026 CDC/ATI schedule?
A. DTaP, IPV, Hib, PCV15/20, RV, and HepB [CORRECT]
B. MMR, varicella, and hepatitis A only
C. Tdap, HPV, and meningococcal conjugate
D. Influenza (inactivated) and pneumococcal polysaccharide (PPSV23)
Correct Answer: A. DTaP, IPV, Hib, PCV15/20, RV, and HepB
Rationale: At the 2-month visit, the 2026 ATI-aligned schedule includes DTaP, IPV, Hib, PCV15 (or PCV20), RV (rotavirus), and
the second HepB dose. MMR and varicella begin at 12–15 months; Tdap/HPV/meningococcal are adolescent vaccines; PPSV23
is for high-risk groups, not routine infants (Ch. 2, Immunizations).
Q4. A nurse is assessing a 12-month-old toddler. Which finding requires IMMEDIATE follow-up?
A. The toddler says two to three words such as "mama" and "dada" specifically.
B. The toddler has not yet begun to walk independently but cruises along furniture.
C. The toddler does not use gestures such as waving goodbye or pointing. [CORRECT]
D. The toddler shows stranger anxiety when approached by an unfamiliar nurse.
Correct Answer: C. The toddler does not use gestures such as waving goodbye or pointing.
Rationale: By 12 months, infants should use social gestures (waving, pointing) — absence is a red flag for autism spectrum
disorder or developmental delay requiring immediate referral. Saying 2–3 words, cruising, and stranger anxiety are all
expected for age. Failure to recognize this social-communication marker is a frequent ATI pitfall (Ch. 1, Developmental
Milestones).
Q5. A 2-year-old is brought to the clinic for a routine visit. The nurse is assessing fine motor development. Which skill
should the toddler be ABLE to demonstrate?
,ATI RN Pediatric Nursing — Edition 12.0 | Complete 400-Question Test Bank Aligned with 2026 ATI Curriculum
A. Copying a circle on paper
B. Building a tower of 6 to 7 blocks [CORRECT]
C. Drawing a person with three body parts
D. Using scissors to cut along a straight line
Correct Answer: B. Building a tower of 6 to 7 blocks
Rationale: A 2-year-old can typically build a tower of 6–7 cubes and scribble. Copying a circle emerges
around age 3; drawing a person with three parts occurs at ~4 years; cutting with scissors is a 5-year
skill. Expecting advanced fine motor milestones too early is a common ATI distractor (Ch. 1,
Developmental Milestones).
Q6. The mother of a 4-month-old exclusively breastfed infant asks about iron supplementation.
Which response is CORRECT based on ATI pediatric nutrition guidelines?
A. Breast milk contains adequate iron; no supplementation is needed until 12 months.
B. Begin iron supplementation of 1 mg/kg/day starting at 4 months of age. [CORRECT]
C. Iron is only needed if the infant is formula-fed with low-iron formula.
D. Delay iron until 6 months, when solid foods will provide sufficient amounts.
Correct Answer: B. Begin iron supplementation of 1 mg/kg/day starting at 4 months of
age.
Rationale: Exclusive breastfeeding beyond 4 months depletes fetal iron stores; ATI recommends 1
mg/kg/day elemental iron starting at 4 months for exclusively breastfed infants. Formula-fed infants
receive iron from iron-fortified formula. Delaying iron risks iron deficiency anemia, the most common
nutritional deficiency in infancy (Ch. 3, Pediatric Nutrition).
Q7. A nurse is teaching injury prevention to parents of a 6-month-old infant. Which anticipatory
guidance is the PRIORITY?
A. Discuss bicycle helmet use and street safety.
B. Recommend installing safety gates at the top and bottom of stairs. [CORRECT]
C. Counsel on firearm safety and peer-pressure resistance.
D. Discuss water safety and never swimming alone.
Correct Answer: B. Recommend installing safety gates at the top and bottom of stairs.
Rationale: A 6-month-old is becoming mobile and rolling/scooting; stair gates are the priority
anticipatory guidance to prevent falls, a leading cause of injury. Bicycle helmets apply to
toddlers/school-age; firearms and water safety are school-age topics. ATI emphasizes matching
anticipatory guidance to the developmental risk profile (Ch. 4, Health Screening & Anticipatory
Guidance).
Q8. At a 15-month well-child visit, which vaccine should the nurse prepare to administer?
A. MMR, varicella, and Hib (if not previously given) [CORRECT]
B. DTaP and IPV boosters only
C. HPV and Tdap
D. Rotavirus and PCV20
Correct Answer: A. MMR, varicella, and Hib (if not previously given)
Rationale: At 12–15 months, the routine schedule includes MMR, varicella, Hib, and PCV. Rotavirus
must be completed by 8 months (age cap). HPV and Tdap are adolescent vaccines. ATI frequently tests
the 12–15 month MMR/varicella timing — and the rule that MMR and varicella must be given on the
same day or ≥28 days apart if not combined (Ch. 2, Immunizations).

Q9. Which statement by the parent of a 3-year-old indicates the need for FURTHER teaching
regarding preschool development?
A. My child can dress and undress with minimal help.
B. My child uses sentences of 5 to 6 words and asks many questions.
C. My child engages in parallel play beside other children without interacting. [CORRECT]
D. My child understands sharing and cooperative play with peers.
Correct Answer: C. My child engages in parallel play beside other children without
interacting.
Rationale: Parallel play is characteristic of toddlers (age 2–3) but a 3-year-old should be moving toward
associative/cooperative play. Dressing self, 5–6 word sentences, and understanding sharing are all
age-appropriate. ATI tests the play-stage progression: solitary → parallel → associative → cooperative
(Ch. 1, Developmental Milestones).
Q10. An adolescent reports feeling sad, sleeping poorly, and losing interest in friends. Which
response by the nurse is the HIGHEST priority?
A. Ask whether the adolescent has had thoughts of harming self or others. [CORRECT]
B. Reassure that mood swings are normal during puberty.
C. Recommend the adolescent join a sports team to socialize more.
D. Schedule a follow-up appointment in 3 months if symptoms persist.
Correct Answer: A. Ask whether the adolescent has had thoughts of harming self or
others.
Rationale: Suicide is a leading cause of adolescent death; any adolescent reporting depressed mood,
insomnia, and anhedonia must be assessed for suicidal ideation immediately. Reassurance without
assessment, suggesting sports, or delaying follow-up misses a life-threatening risk. ATI emphasizes
universal suicide screening for adolescents (Ch. 1, Developmental Milestones & Adolescent Health).
Q11. A nurse is calculating a 6-month-old infant's immunization record. The infant received the
birth dose of HepB and the first dose at 1 month. Which vaccine is CONTRAINDICATED at the
6-month visit?
A. Third dose of HepB
B. Third dose of DTaP
C. Measles, mumps, and rubella (MMR) vaccine [CORRECT]
D. Inactivated polio vaccine (IPV)
Correct Answer: C. Measles, mumps, and rubella (MMR) vaccine
Rationale: MMR is a live vaccine routinely given at 12–15 months and is not part of the 6-month
schedule. The third HepB, third DTaP, and third IPV are all due at 6 months. ATI often tests recognition
of which vaccines are live (MMR, varicella, LAIV, rotavirus) vs. inactivated — live vaccines are
contraindicated in severe immunocompromise and pregnancy (Ch. 2, Immunizations).
Q12. A 9-month-old infant is brought to the clinic. The parent reports the baby pulls to stand, says
"mama" and "dada" nonspecifically, and uses a pincer grasp. Which finding requires further
evaluation?
A. Pulls to a standing position holding onto furniture
B. Says "mama" and "dada" nonspecifically at 9 months
C. Uses a neat pincer grasp to pick up small objects
