ATI Pediatrics Proctored Exam V1 | 2026
Q&A with Rationale (ATI Pediatrics
Proctored Exam 2026)
1. A nurse is assessing a 4-month-old infant. Which of the following developmental
milestones should the nurse expect to observe?
A. Sitting upright without support
B. Using a pincer grasp to pick up small objects
C. Rolling from back to side
D. Saying three to five meaningful words
Correct Answer: C
Rationale: A 4-month-old infant should be able to roll from their back to their side and
from their stomach to their back. Sitting without support typically occurs around 6 to 8
months of age. A pincer grasp develops around 8 to 10 months, and speaking meaningful
words is expected around 12 months.
2. A nurse is teaching parents of a toddler about home safety. Which of the following
instructions should the nurse include?
A. Set the water heater temperature to 54°C (130°F)
B. Store household cleaning products in a locked cabinet
C. Keep the toddler in a forward-facing car seat until age 4
,D. Use balloons as a safe toy for indoor play
Correct Answer: B
Rationale: Toddlers are naturally curious and mobile, putting them at high risk for
poisoning; therefore, all toxic substances should be locked away. Water heaters should be
set to no higher than 49°C (120°F) to prevent scald burns. Latex balloons are a significant
choking hazard and should not be given to toddlers.
3. A nurse is caring for an infant who has pyloric stenosis. Which of the following findings
should the nurse expect?
A. Currant jelly-like stools
B. Bile-stained emesis
C. Projectile vomiting after feedings
D. Weight gain despite frequent spitting up
Correct Answer: C
Rationale: Hypertrophic pyloric stenosis causes a narrowing of the pyloric sphincter,
leading to forceful, projectile vomiting. This condition typically manifests in the first few
weeks of life. Infants often present with weight loss and dehydration because they cannot
retain feedings.
4. A nurse is assessing a school-age child with cystic fibrosis. Which of the following findings
should the nurse report to the provider immediately?
A. Steatorrhea
, B. Delayed growth
C. Clubbing of the fingers
D. Oxygen saturation 85%
Correct Answer: D
Rationale: An oxygen saturation of 85% indicates significant respiratory distress and
hypoxia, requiring immediate intervention. While steatorrhea, finger clubbing, and delayed
growth are common findings in cystic fibrosis, they are chronic symptoms. Acute
hypoxemia is a priority life-threatening concern.
5. A nurse is teaching the mother of a child who has iron deficiency anemia about dietary
sources. Which of the following foods should the nurse recommend?
A. Cow’s milk
B. Applesauce
C. White bread
D. Lentils
Correct Answer: D
Rationale: Lentils are an excellent source of non-heme iron for children with anemia.
Cow’s milk is low in iron and can actually interfere with iron absorption if consumed in
excess. The nurse should encourage iron-rich foods like beans, meats, and fortified cereals.
