QUESTION 1: PEDIATRICS (CARDIOVASCULAR COMPLICATIONS)
A nurse is assessing a 4-year-old child diagnosed with Tetralogy of Fallot who suddenly
becomes severely dyspneic, cyanotic, and agitated while crying. Which action should the
nurse implement first?
A) Administer a prescribed dose of intravenous morphine sulfate.
B) Place the child in a knee-chest position.
C) Initiate oxygen therapy at 10 L/min via a non-rebreather mask.
D) Establish immediate peripheral intravenous access.
Correct Answer: B
HESI Category: Physiological Adaptation / Pediatrics
Next-Gen NCJMM Rationale:
Why it's correct: The child is experiencing a hypercyanotic spell ("tet spell"). Placing
the child in a knee-chest position increases systemic vascular resistance, which
decreases the right-to-left shunt across the ventricular septal defect, forcing more
blood into the pulmonary artery to improve oxygenation.
Why others are incorrect: Administering morphine (Option A) and giving oxygen
(Option C) are appropriate secondary steps, but physical positioning is immediate,
costs zero time, and is the absolute first intervention. Starting an IV (Option D) during
an active spell can increase agitation and worsen the spasm.
Test-Taking Tip: For any "Tet Spell" in a Tetralogy of Fallot patient, always look for the
knee-chest position or squatting as the priority action.
QUESTION 2: PEDIATRICS (GROWTH AND DEVELOPMENT)
A nurse is conducting a well-child assessment on an 18-month-old toddler. Which
developmental milestone should the nurse expect the child to have successfully achieved?
A) Building a tower of 3 to 4 blocks.
B) Skipping on alternating feet.
C) Using a tricycle independently.
D) Tying their own shoelaces.

Correct Answer: A
HESI Category: Health Promotion and Maintenance / Pediatrics
Next-Gen NCJMM Rationale:
Why it's correct: An 18-month-old toddler is expected to possess the fine motor
skills necessary to stack a tower of 3 to 4 blocks.
Why others are incorrect: Riding a tricycle (Option C) occurs around 3 years of age.
Skipping (Option B) is a 4-to-5-year milestone. Tying shoelaces (Option D) is a fine
motor skill expected around 5 years of age.
Test-Taking Tip: Toddler gross and fine motor coordination scales expand rapidly.
Memorize block-stacking averages: 18 months = 3–4 blocks; 24 months = 6–7 blocks.
QUESTION 3: PEDIATRICS (RESPIRATORY INFECTIOUS DISEASE)
A 2-year-old child is brought to the emergency department with a barking cough, inspiratory
stridor, and mild intercostal retractions. The parents state the symptoms worsened suddenly
at night. Which condition should the nurse suspect?
A) Acute Epiglottitis
B) Acute Laryngotracheobronchitis (Croup)
C) Bronchiolitis secondary to RSV
D) Foreign Body Aspiration
Correct Answer: B
HESI Category: Physiological Adaptation / Pediatrics
Next-Gen NCJMM Rationale:
Why it's correct: Croup (laryngotracheobronchitis) typically affects children under 3
years old, presents with a characteristic barking or seal-like cough, inspiratory stridor,
and symptoms that notoriously aggravate during the night.
Why others are incorrect: Epiglottitis (Option A) is a medical emergency presenting
with high fever, dysphagia, drooling, and an anxious tripod position, without a loud
barking cough. Bronchiolitis (Option C) manifests with wheezing and abundant
secretions. Foreign body aspiration (Option D) has an abrupt, unprovoked onset
without preceding viral or nighttime triggers.

Test-Taking Tip: Associate a barking, seal-like cough and nighttime worsening
immediately with Croup.
QUESTION 4: PEDIATRICS (GASTROINTESTINAL COMPLICATIONS)
A nurse is assessing an 8-week-old infant brought to the clinic for severe, non-bilious
projectile vomiting immediately after feedings. The infant is irritable, appears hungry, and
has a palpable olive-shaped mass in the right upper quadrant. Which condition should the
nurse anticipate?
A) Intussusception
B) Hirschsprung's Disease
C) Hypertrophic Pyloric Stenosis
D) Gastroesophageal Reflux
Correct Answer: C
HESI Category: Physiological Adaptation / Pediatrics
Next-Gen NCJMM Rationale:
Why it's correct: Hypertrophic pyloric stenosis causes severe narrowing of the pyloric
sphincter. The classic symptoms are non-bilious projectile vomiting, persistent
hunger, and a palpable olive-shaped mass in the epigastric or right upper quadrant
region.
Why others are incorrect: Intussusception (Option A) presents with severe
abdominal pain and "current-jelly" stools. Hirschsprung's (Option B) causes ribbon-
like stools and a lack of meconium passage. GERD (Option D) causes spitting up but
not forceful, projectile vomiting or an olive-shaped mass.
Test-Taking Tip: Look for pathognomonic buzzwords: Olive-shaped mass + Projectile
vomiting = Pyloric Stenosis.
QUESTION 5: PEDIATRICS (INFECTIOUS EXANTHEMA)
A 6-year-old child is diagnosed with varicella (chickenpox). The nurse is providing home-care
safety instructions to the parents. Which medication is strictly contraindicated for fever
management in this child?
