ATI RN PEDIATRIC NURSING PROCTORED EXAM 2026 | NGN PRACTICE
QUESTIONS
DOCUMENT OVERVIEW
• Comprehensive study resource containing latest ATI RN Pediatric Nursing
proctored exam questions with detailed rationales—designed to strengthen clinical
reasoning and exam readiness for RN licensure candidates.
• Study strategically by reviewing each question with rationale, focusing on
identifying key clinical indicators, nursing interventions, and growth/developmental
principles to master all pediatric nursing domains.
QUESTION 1
A 3-year-old child is admitted with suspected croup. Which clinical
manifestation would the nurse expect to assess?
A) Barking, seal-like cough with inspiratory stridor
B) Productive cough with greenish sputum
C) Wheezing heard on expiration
D) High fever with cherry-red throat
E) Drooling with tripod positioning
CORRECT ANSWER: A) Barking, seal-like cough with inspiratory stridor
,RATIONALE: Croup (laryngotracheobronchitis) is characterized by a distinctive
barking, seal-like cough with inspiratory stridor caused by subglottic inflammation.
This is the hallmark sign of croup in children. Option B describes bronchitis with
productive cough, Option C indicates asthma or reactive airway disease, Option D
describes acute pharyngitis, and Option E are signs of epiglottitis. The barking
cough is pathognomonic for croup.
QUESTION 2
A 6-month-old infant is brought to the clinic for a well-child visit. At what age
should the nurse expect the infant to have doubled their birth weight?
A) 2 months
B) 4 months
C) 6 months
D) 9 months
E) 12 months
CORRECT ANSWER: C) 6 months
RATIONALE: Infants typically double their birth weight by 6 months of age. This is
an important developmental milestone used to assess adequate growth and
nutrition. By 12 months (1 year), the infant should triple their birth weight. Birth
weight is usually regained by 10-14 days of age in healthy newborns. Options A, B,
D, and E represent incorrect developmental timelines for weight gain milestones.
QUESTION 3
A 4-year-old child with acute leukemia is experiencing severe pain related to
mouth ulcers from chemotherapy. Which intervention would be most
appropriate for the nurse to implement?
A) Apply lemon juice to the ulcers to promote healing
B) Use a soft toothbrush and rinse with normal saline or salt water solution
,C) Restrict oral intake to prevent further irritation
D) Apply hydrogen peroxide solution directly to ulcers
E) Use hot water for mouth rinses to stimulate blood flow
CORRECT ANSWER: B) Use a soft toothbrush and rinse with normal saline or
salt water solution
RATIONALE: Oral care for a child with chemotherapy-induced mucositis should
include gentle cleaning with a soft toothbrush and rinsing with normal saline or salt
water solution. This promotes healing and reduces infection risk while minimizing
discomfort. Lemon juice and hydrogen peroxide are irritating and contraindicated.
Hot water increases irritation and pain. Restricting oral intake is not appropriate as
nutrition is crucial during cancer treatment. Gentle saline rinses are the gold
standard for mucositis care.
QUESTION 4
An 8-year-old child is admitted with diabetic ketoacidosis (DKA). Which finding
would the nurse anticipate?
A) Slow, shallow respirations
B) Blood glucose less than 100 mg/dL
C) Fruity-smelling breath
D) Decreased level of consciousness
E) Hypertension
CORRECT ANSWER: C) Fruity-smelling breath
RATIONALE: Diabetic ketoacidosis causes ketone production, which results in
fruity-smelling breath (from acetone exhalation). In DKA, respirations are typically
fast and deep (Kussmaul respirations) to compensate for metabolic acidosis, not
slow and shallow. Blood glucose is elevated (often >250 mg/dL), not decreased.
While altered mental status can occur in severe cases, fruity breath is a more
, consistent early finding. Hypotension, not hypertension, typically occurs in DKA. The
fruity odor is a classic sign resulting from ketone metabolism.
QUESTION 5
A 2-year-old toddler has a normal rectal temperature reading of 37.5°C
(99.5°F). Which statement by the nurse best explains normal temperature
variation in toddlers?
A) Toddlers have a more stable temperature regulation system than infants
B) Rectal temperatures are always 0.5°C higher than oral temperatures
C) Normal body temperature in toddlers ranges from 36.5°C to 37.5°C
D) Toddlers have lower metabolic rates, resulting in lower baseline temperatures
E) Temperature readings should only be taken rectally in children under 5 years
CORRECT ANSWER: C) Normal body temperature in toddlers ranges from
36.5°C to 37.5°C
RATIONALE: Normal body temperature in toddlers typically ranges from 36.5°C to
37.5°C (97.7°F to 99.5°F). Toddlers still have less developed temperature regulation
compared to older children and adults, making them more prone to temperature
fluctuations. The 0.5°C difference between rectal and oral readings is approximate
but not absolute. While metabolic rate is relatively high in toddlers, it does not
result in lower baseline temperatures. Temperature can be taken via multiple
routes (rectal, axillary, tympanic, temporal) depending on age and clinical situation.
Option C correctly identifies the normal temperature range for toddlers.
QUESTION 6
A 5-year-old child is scheduled for surgery tomorrow. Which pre-operative
instruction should the nurse emphasize to the parents regarding NPO
(nothing by mouth) status?
A) NPO from midnight the night before surgery
