ATI Pediatrics Proctored Exam (Questions And
Answers with useful Rationales– 2026 Retake Styled
revision <Updated Version>)
1.
A nurse is assessing a 6-month-old infant during a routine visit. Which finding requires further
evaluation?
A. The infant rolls from back to stomach, transfers objects between hands, and responds to
caregiver voice with social smiling and cooing sounds
B. The infant demonstrates persistent head lag when pulled from a supine position to sitting, with
minimal neck muscle control observed
C. The infant becomes briefly uncomfortable when separated from the caregiver but is easily
consoled upon return
D. The infant turns toward sounds and visually tracks moving objects across the midline
Answer: B
Rationale: Persistent head lag at 6 months suggests delayed motor development or
neuromuscular dysfunction, possibly indicating cerebral palsy, muscular weakness, or CNS
impairment. By this age, infants should have near-complete head control. The other options
represent normal developmental milestones for 6 months.
2.
A toddler with moderate dehydration is receiving oral rehydration therapy. Which finding
indicates improvement?
A. Continued dry mucous membranes with slight increase in activity level and persistent poor
skin turgor
B. Capillary refill less than 2 seconds, improved urine output, and more alert behavior compared
to admission baseline
C. Ongoing irritability, decreased tears, and continued refusal of oral intake despite
encouragement
D. Elevated heart rate above age norms with only minimal improvement in hydration status
Answer: B
Rationale: Improvement in dehydration is best measured by restoration of perfusion and renal
function. Capillary refill under 2 seconds indicates improved circulatory volume. Increased
,urine output reflects adequate renal perfusion and hydration restoration. Behavioral changes
alone are not reliable indicators because they may lag behind physiological recovery.
3.
A parent is receiving teaching about preventing sudden infant death syndrome. Which statement
indicates correct understanding?
A. “I will place my baby on the stomach because it reduces choking risk during sleep.”
B. “I will use soft pillows and stuffed toys in the crib to make sleep more comfortable and
secure.”
C. “I will place my baby on the back to sleep on a firm mattress with no loose bedding or soft
objects.”
D. “I will keep the room very warm and cover the baby with heavy blankets to prevent cold
stress.”
Answer: C
Rationale: Supine positioning reduces risk of airway obstruction and CO₂ rebreathing. Firm
mattresses and removal of loose bedding reduce suffocation risk. Overheating increases
metabolic demand and is a known SIDS risk factor. Stomach sleeping increases risk of airway
compromise.
4.
A child receiving amoxicillin develops rash, facial swelling, and wheezing shortly after
administration. What is the priority action?
A. Continue medication and monitor closely for progression of symptoms
B. Administer oral antihistamine and reassess after 1 hour
C. Stop the medication immediately and initiate emergency treatment for anaphylaxis
D. Document reaction and notify provider during routine follow-up
Answer: C
Rationale: This is a classic anaphylactic reaction, involving airway edema,
bronchoconstriction, and systemic histamine release. Wheezing indicates respiratory
compromise. Facial swelling suggests angioedema. Immediate discontinuation and emergency
treatment with epinephrine, oxygen, and airway support are required to prevent respiratory
collapse.
5.
A 2-year-old is suspected of having epiglottitis. What is the priority nursing intervention?
,A. Perform throat inspection using a tongue depressor to confirm inflammation
B. Place the child supine to assist with visualization and comfort
C. Prepare for emergency airway management including possible intubation
D. Encourage oral fluids to reduce throat inflammation and maintain hydration
Answer: C
Rationale: Epiglottitis causes rapid airway obstruction due to inflammation of the epiglottis.
Any throat examination may trigger laryngospasm and complete airway closure. Airway
management is the priority before diagnostics or medication administration.
6.
A child with severe immunosuppression due to chemotherapy is due for immunizations. Which
vaccine is contraindicated?
A. Inactivated polio vaccine
B. Hepatitis B vaccine
C. Measles, mumps, rubella vaccine
D. DTaP vaccine
Answer: C
Rationale: MMR is a live attenuated vaccine, meaning it contains weakened organisms that
can still replicate. In immunocompromised patients, this may lead to uncontrolled infection.
Inactivated vaccines remain safe because they cannot replicate.
7.
A school-age child demonstrates correct use of a metered-dose inhaler when they:
A. Inhale rapidly through the nose immediately after pressing the inhaler
B. Exhale fully, place lips around mouthpiece, and inhale slowly while activating the medication
C. Hold breath before pressing the inhaler to maximize lung expansion
D. Use the inhaler only during severe wheezing episodes
Answer: B
Rationale: Proper MDI use ensures medication reaches the lower airways. Full exhalation clears
residual air, and slow inhalation allows aerosol particles to deposit in bronchioles rather than the
oropharynx. Breath-holding improves alveolar absorption.
8.
Which finding is most reliable for diagnosing dehydration in an infant?
, A. Irritability and crying without tears
B. Sunken anterior fontanelle and poor skin turgor
C. Decreased appetite and reduced feeding frequency
D. Dry lips and mild lethargy
Answer: B
Rationale: The anterior fontanelle reflects intracranial fluid volume in infants. A sunken
fontanelle is a strong objective indicator of significant dehydration. Other signs may be
subjective or appear later in the dehydration process.
9.
A child with nephrotic syndrome is expected to have which clinical manifestation?
A. Hematuria and flank pain due to glomerular inflammation
B. Massive proteinuria leading to generalized edema and hypoalbuminemia
C. Increased urine output due to hormonal imbalance
D. Painful urination due to urinary tract infection
Answer: B
Rationale: Nephrotic syndrome involves damage to the glomerular filtration barrier, allowing
protein loss in urine. Loss of albumin decreases plasma oncotic pressure, causing fluid to shift
into tissues, resulting in edema.
10.
Which toy is most appropriate for a 10-month-old infant?
A. Small building blocks with detachable parts
B. Large soft blocks that can be grasped and stacked safely
C. Small marbles used for fine motor skill development
D. Toys with sharp edges to enhance sensory exploration
Answer: B
Rationale: At this age, infants explore objects orally. Large soft toys reduce choking risk and
support safe motor development. Small objects pose aspiration hazards due to immature
swallowing coordination.

A child in sickle cell crisis is admitted with severe pain and low oxygen saturation. Which
position is most appropriate?
