Section A: Pediatric Assessment & Respiratory Emergencies
(Questions 1–15)
Q1: A 3-year-old child is brought to the emergency department with increased work of
breathing. The nurse uses the Pediatric Assessment Triangle (PAT) and first evaluates
the child's muscle tone, interactiveness, consolability, gaze, and speech. These
assessments correspond to which PAT component?
A. Work of Breathing
B. Circulation to Skin
C. Appearance [CORRECT]
D. Airway Patency
Correct Answer: C
Rationale: The TICLS mnemonic (Tone, Interactiveness, Consolability, Look/Gaze,
Speech/Cry) is used specifically during the APPEARANCE step of PAT to assess mental
status and overall condition. Work of Breathing (A) assesses respiratory effort;
Circulation to Skin (B) assesses perfusion.
Q2: A nurse is assessing a 6-month-old infant and notes nasal flaring, grunting, and
subcostal retractions. These findings indicate:
A. Normal newborn breathing
B. Increased work of breathing [CORRECT]
C. Adequate ventilation
D. Neuromuscular weakness
Correct Answer: B
Rationale: Nasal flaring, grunting, and retractions (intercostal, subcostal, substernal,
suprasternal) are classic signs of increased work of breathing. Grunting is the infant's
attempt to maintain functional residual capacity. These are abnormal and indicate
respiratory distress.
,Q3: A 2-year-old with pneumonia is noted to have central cyanosis. The PALS provider
recognizes that cyanosis is:
A. An early sign of mild respiratory distress
B. A late sign indicating significant hypoxemia [CORRECT]
C. A normal finding in toddlers
D. Unrelated to oxygenation status
Correct Answer: B
Rationale: Cyanosis is a LATE sign of respiratory distress, indicating significant
hypoxemia (typically SpO2 < 80%). Early signs include tachypnea, nasal flaring, and
retractions. Providers should not wait for cyanosis to intervene.
Q4: A 4-month-old infant presents with respiratory distress that has progressed to
bradycardia, decreased respiratory rate, and diminished breath sounds. The provider
recognizes this as:
A. Compensated respiratory distress
B. Respiratory failure [CORRECT]
C. Normal sleep pattern
D. Anxiety response
Correct Answer: B
Rationale: Respiratory failure is characterized by inadequate oxygenation/ventilation
with signs including bradycardia (late sign), slowed respiratory rate, decreased breath
sounds, and low O2 saturation. Bradycardia in respiratory distress signals impending
cardiac arrest.
Q5: An 8-month-old with bronchiolitis is noted to have a prolonged expiratory phase and
audible wheezing. These findings are characteristic of:
A. Upper airway obstruction
B. Lower airway obstruction [CORRECT]
C. Lung tissue disease
D. Neuromuscular respiratory failure
Correct Answer: B
Rationale: Lower airway obstruction (asthma, bronchiolitis) causes prolonged expiratory
phase and wheezing due to bronchospasm and mucus plugging. Upper airway
obstruction (A) presents with stridor and inspiratory difficulty.
, Q6: A 2-year-old with croup presents with a barking cough and inspiratory stridor. The
provider prepares to administer:
A. Albuterol nebulizer only
B. Nebulized epinephrine and corticosteroids [CORRECT]
C. Immediate intubation
D. Antibiotics
Correct Answer: B
Rationale: Moderate to severe croup is treated with nebulized epinephrine (reduces
airway edema) and corticosteroids (dexamethasone, reduces inflammation). Albuterol
(A) is for lower airway disease; intubation (C) is reserved for severe respiratory failure.
Q7: A 7-year-old with a history of asthma presents with severe exacerbation, wheezing,
and increased work of breathing. First-line treatment is:
A. Corticosteroids alone
B. Albuterol with or without ipratropium bromide [CORRECT]
C. Magnesium sulfate only
D. Immediate intubation
Correct Answer: B
Rationale: Severe asthma exacerbation first-line treatment is albuterol (beta-agonist,
bronchodilation) with or without ipratropium bromide (anticholinergic). Corticosteroids
(A) are adjunctive; magnesium (C) is second-line; intubation (D) is for respiratory failure.
Q8: A 3-month-old with RSV bronchiolitis presents with fever, grunting, and wet cough.
The provider recognizes that grunting indicates:
A. Normal infant vocalization
B. Attempt to maintain functional residual capacity and prevent alveolar collapse
[CORRECT]
C. Seizure activity
D. Gastroesophageal reflux
Correct Answer: B
Rationale: Grunting is an infant compensatory mechanism—expiring against a partially
closed glottis to maintain positive end-expiratory pressure and prevent alveolar
collapse. It signifies significant respiratory distress in bronchiolitis.
Q9: A child with chronic neuromuscular disease presents in respiratory distress. The
most critical initial intervention is:
