INTRODUCTION
Prepare confidently for your ATI Pediatrics Proctored Exam with this comprehensive 2026
NGN-style practice test, designed to match real exam difficulty and format. This resource
includes 159 high-quality questions with verified answers and detailed rationales, helping
you master critical pediatric nursing concepts and Next Generation NCLEX (NGN) clinical
judgment skills.
This exam covers key pediatric topics, including respiratory disorders, dehydration, infectious
diseases, neurological conditions, endocrine emergencies (DKA), cardiac conditions, and growth
and development milestones. Each question is carefully structured to reflect ATI-style
prioritization, SATA, and case-based scenarios, ensuring you are fully prepared for real
testing conditions.
Perfect for nursing students preparing for ATI RN Pediatrics Proctored Exam 2026, this
resource is your ultimate study companion for success.
Case Scenario (Questions 1–3)
A 4-year-old child is admitted with acute asthma exacerbation. The child has nasal flaring,
intercostal retractions, audible wheezing, and oxygen saturation of 89% on room air.
1. What is the nurse’s priority action for this child experiencing acute respiratory
distress and hypoxemia?
A. Offer oral fluids to thin secretions
B. Apply supplemental oxygen and perform rapid respiratory assessment
,C. Allow the child to rest quietly without intervention
D. Notify the provider before initiating care
Rationale:
This child is showing signs of moderate to severe respiratory distress (low SpO₂,
retractions, nasal flaring). According to ABC priorities, airway and breathing come first.
Oxygen must be applied immediately while assessing airway patency, respiratory effort, and
need for further interventions (e.g., bronchodilators). Delaying oxygen can worsen hypoxia
and lead to respiratory failure.
2. (SATA) Which interventions should the nurse implement immediately for this child
with asthma exacerbation?
A. Administer prescribed short-acting bronchodilator (e.g., albuterol)
B. Restrict oral fluids to prevent aspiration
C. Continuously monitor oxygen saturation with pulse oximetry
D. Place child in supine position for comfort
E. Position child upright (High Fowler’s) to improve lung expansion
Rationale:
Bronchodilators relieve bronchospasm and improve airflow.
Continuous SpO₂ monitoring tracks response to treatment.
High Fowler’s maximizes lung expansion and decreases work of breathing.
Fluids should not be restricted unless contraindicated; hydration helps thin
secretions.
Supine positioning worsens respiratory effort and should be avoided.
3. Which assessment finding indicates immediate life-threatening deterioration in this
pediatric client?
A. Audible wheezing throughout lung fields
B. Mild intercostal retractions
C. Diminished or absent breath sounds (“silent chest”)
D. Increased respiratory rate
,Rationale:
A “silent chest” means little to no air movement, indicating severe airway obstruction
and impending respiratory failure. Wheezing actually requires airflow; when wheezing
disappears in a distressed child, it is a critical warning sign, not improvement.
4. A nurse is assessing pain in a 2-year-old child who cannot verbally describe pain.
Which tool is most appropriate?
A. Numeric rating scale (0–10)
B. FLACC scale (Face, Legs, Activity, Cry, Consolability)
C. Visual analog scale
D. Verbal descriptor scale
Rationale:
The FLACC scale is specifically designed for infants and toddlers. It evaluates observable
behaviors to quantify pain. Numeric and verbal scales require cognitive and language
abilities not yet developed at this age.
5. Which immunization is administered at birth in many countries to help prevent
severe forms of tuberculosis?
A. Hepatitis B
B. DTaP
C. BCG (Bacillus Calmette-Guérin) vaccine
D. IPV
Rationale:
The BCG vaccine is commonly given at birth in TB-endemic regions to prevent severe
childhood tuberculosis (e.g., TB meningitis). Hepatitis B is also given at birth but does
not protect against TB.
6. A nurse is assessing an infant with suspected dehydration. Which finding
indicates moderate to severe dehydration?
, A. Moist mucous membranes
B. Active crying with tears
C. Sunken fontanelle with decreased urine output
D. Slight increase in appetite
Rationale:
A sunken anterior fontanelle reflects decreased intracranial fluid volume, and reduced
urine output indicates poor renal perfusion. These are late and serious signs of
dehydration in infants requiring prompt intervention.
7. When administering oral medication to a resistant toddler, which technique is
safest and most effective?
A. Force the medication quickly into the mouth
B. Use an oral syringe and administer slowly along the side of the cheek
C. Mix medication into a full bottle of milk
D. Allow the child to self-administer without supervision
Rationale:
Administering medication along the side of the cheek (buccal area) reduces risk of
aspiration and gagging. Mixing in large food amounts is unsafe because the child may not
finish it, leading to incomplete dosing.
8. A child has a temperature of 39°C (102.2°F). What is the most appropriate nursing
intervention?
A. Wrap the child in blankets
B. Administer antipyretics and encourage oral fluid intake
C. Restrict fluid intake to prevent vomiting
D. Keep the room warm and quiet
Rationale:
Fever increases metabolic demand and fluid loss. Antipyretics
(acetaminophen/ibuprofen) reduce fever, and fluids prevent dehydration. Overheating the
child can worsen hyperthermia.
