1. PEDIATRIC ASSESSMENT AND RECOGNITION
Q1. A child presents to the emergency department with increased
work of breathing. Which approach should the PALS provider use
first?
A) Obtain a complete medical history
B) Perform a rapid systematic assessment of airway, breathing, and
circulation
C) Obtain a detailed dietary history
D) Begin discharge planning
Correct Answer: B) Perform a rapid systematic assessment of airway,
breathing, and circulation
Rationale: PALS begins with rapid recognition of immediate threats to
airway, breathing, and circulation before obtaining a detailed history.
Q2. Which finding is most concerning for pediatric respiratory
failure?
A) Mild tachypnea with normal interaction
B) Increasing fatigue with decreasing respiratory effort
C) Mild nasal congestion
D) Normal oxygenation
Correct Answer: B) Increasing fatigue with decreasing respiratory effort
,Rationale: Decreasing respiratory effort in a child with distress suggests
respiratory muscle fatigue and impending failure.
Q3. Which finding is characteristic of compensated shock in a child?
A) Hypotension
B) Tachycardia with delayed capillary refill
C) Profound bradycardia
D) Immediate cardiac arrest
Correct Answer: B) Tachycardia with delayed capillary refill
Rationale: Children can maintain blood pressure through compensatory
mechanisms while peripheral perfusion becomes impaired.
Q4. Which finding suggests decompensated shock?
A) Normal blood pressure and warm extremities
B) Hypotension with altered mental status
C) Mild tachycardia after crying
D) Normal capillary refill
Correct Answer: B) Hypotension with altered mental status
Rationale: Hypotension indicates failure of compensatory mechanisms and
significant circulatory compromise.
Q5. Which assessment finding should prompt immediate
intervention?
A) Central cyanosis
B) Mild cough
C) Normal interaction
D) Stable temperature
Correct Answer: A) Central cyanosis
Rationale: Central cyanosis indicates inadequate oxygenation and requires
immediate evaluation and support.
Q6. Which finding is most concerning in an infant with respiratory
distress?
A) Nasal flaring and grunting
B) Occasional sneezing
C) Strong cry
D) Normal feeding
, Correct Answer: A) Nasal flaring and grunting
Rationale: Nasal flaring and grunting are signs of increased work of
breathing.
Q7. Which finding suggests severe respiratory distress rather than
mild distress?
A) Marked retractions with cyanosis
B) Mild tachypnea
C) Normal speech
D) Normal activity
Correct Answer: A) Marked retractions with cyanosis
Rationale: Severe respiratory effort combined with impaired oxygenation
indicates significant respiratory compromise.
Q8. Which change most strongly indicates progression from
respiratory distress to respiratory failure?
A) Increased respiratory effort followed by fatigue and decreased effort
B) Mild tachypnea
C) Mild cough
D) Normal oxygen saturation
Correct Answer: A) Increased respiratory effort followed by fatigue and
decreased effort
Rationale: A child may compensate initially with increased effort but later
deteriorate when respiratory muscles become fatigued.
Q9. Which pediatric finding may be an early sign of shock?
A) Tachycardia
B) Hypotension
C) Cardiac arrest
D) Fixed pupils
Correct Answer: A) Tachycardia
Rationale: Tachycardia is often an early compensatory response to reduced
circulating volume or impaired perfusion.
Q10. Which is a late sign of pediatric shock?
