SECTION 1: Systematic Approach & Pediatric Assessment (Questions 1–10)
Q1: A 3-year-old child is brought to the emergency department after a fall from playground equipment.
Using the Pediatric Assessment Triangle (PAT), you observe the child is crying but consolable, has mild
intercostal retractions, and capillary refill of 2 seconds. What is your initial classification of this child?
A. Respiratory failure; immediate intubation required
B. Respiratory distress; requires immediate intervention but not yet intubation
C. Respiratory distress; requires immediate intubation
D. Respiratory failure; requires supplemental oxygen only [CORRECT]
Correct Answer: B
Rationale: The PAT reveals respiratory distress, not failure. The child has a good appearance
(consolable), increased work of breathing (intercostal retractions), and adequate circulation (capillary
refill 2 seconds). Respiratory failure would present with altered appearance (lethargy/agitation), severe
work of breathing, or poor circulation. Option A incorrectly labels this as failure and mandates
intubation prematurely. Option C correctly identifies distress but incorrectly mandates immediate
intubation. Option D is internally inconsistent (failure + oxygen only). Per 2020 AHA Guidelines, this child
needs intervention but maintains adequate gas exchange without immediate airway intervention.
Q2: During your primary assessment of a 5-year-old trauma patient, you note the following: alert and
crying, respiratory rate 45/min with nasal flaring, heart rate 140/min, capillary refill 3 seconds, blood
pressure 85/55 mmHg. Which component of the PAT is most concerning?
A. Appearance (alert and crying indicates adequate perfusion to brain)
B. Work of breathing (tachypnea with nasal flaring indicates respiratory distress) [CORRECT]
C. Circulation to skin (3-second capillary refill is normal for age)
D. Blood pressure (85/55 is hypotensive for a 5-year-old)
,Correct Answer: B
Rationale: The PAT prioritizes appearance, work of breathing, and circulation to skin—blood pressure
is assessed during the primary survey, not the PAT. While 85/55 is borderline low for age, the most
concerning PAT finding is the work of breathing (nasal flaring + tachypnea indicating increased effort).
Three-second capillary refill is borderline abnormal (normal <2-3 seconds). The child's appearance
remains reassuring (alert), making respiratory compromise the priority. AHA PALS emphasizes that the
PAT is designed for rapid visual assessment before touching the patient; blood pressure measurement
occurs during the primary assessment.
Q3: You are assessing a 6-month-old infant with suspected sepsis. Which vital sign combination is most
consistent with compensated shock in this age group?
A. Heart rate 160/min, blood pressure 70/45 mmHg, capillary refill 2 seconds
B. Heart rate 180/min, blood pressure 65/40 mmHg, capillary refill 4 seconds [CORRECT]
C. Heart rate 120/min, blood pressure 85/55 mmHg, capillary refill 1 second
D. Heart rate 200/min, blood pressure 55/30 mmHg, capillary refill 5 seconds
Correct Answer: B
Rationale: Compensated shock is characterized by tachycardia (early compensatory mechanism),
normal or near-normal blood pressure (compensatory vasoconstriction maintains pressure), and
delayed capillary refill (>3 seconds indicates poor perfusion). For a 6-month-old, normal HR is 100-160;
180 represents significant tachycardia. BP 65/40 is at the lower limit of normal (MAP ~48, acceptable for
age). Four-second capillary refill confirms poor perfusion despite maintained pressure. Option A shows
adequate perfusion (2-second refill). Option C is completely normal. Option D represents
decompensated shock (hypotension + extreme tachycardia). AHA PALS teaches that hypotension is a
late finding in pediatric shock.
Q4: A 2-year-old child (12 kg) requires bag-mask ventilation (BMV) during a respiratory emergency.
What is the appropriate ventilation rate and technique?
A. 20 breaths/min, observe for visible chest rise, use C-E clamp technique [CORRECT]
B. 30 breaths/min, observe for visible chest rise, use E-C clamp technique
C. 12 breaths/min, deliver tidal volume 10 mL/kg, use two-hand technique
D. 40 breaths/min, deliver tidal volume 15 mL/kg, use one-hand technique
Correct Answer: A
Rationale: For spontaneous breathing children requiring BMV support, the rate is 20 breaths/min (one
breath every 3 seconds). The C-E clamp technique is correct: thumb and index finger form a "C" on the
, mask, while the remaining fingers form an "E" to lift the jaw. Visible chest rise confirms adequate tidal
volume (approximately 6-7 mL/kg in children, not 10-15 mL/kg which risks barotrauma). Option B
reverses the clamp terminology. Option C describes an adult rate and excessive volume. Option D is too
fast with excessive volume. AHA PALS 2020 emphasizes avoiding hyperventilation and gastric
insufflation.
Q5: You need to calculate the endotracheal tube (ETT) size for an 8-year-old child requiring intubation.
The child has no contraindications to cuffed tubes. What is the correct formula and calculated size?
A. Uncuffed: (8 ÷ 4) + 4 = 6.0 mm
B. Cuffed: (8 ÷ 4) + 3 = 5.0 mm [CORRECT]
C. Cuffed: (8 ÷ 2) + 12 = 16.0 mm
D. Uncuffed: (8 ÷ 2) + 12 = 16.0 mm
Correct Answer: B
Rationale: The cuffed ETT formula is (age ÷ 4) + 3, yielding 5.0 mm for an 8-year-old. AHA PALS and
current pediatric airway guidelines favor cuffed tubes in most situations (better seal, reduced aspiration
risk, no need to change tube if leak occurs). The uncuffed formula [(age ÷ 4) + 4] would give 6.0 mm
(Option A), but cuffed tubes are preferred. Options C and D use completely incorrect formulas [(age ÷ 2)
+ 12] that would produce dangerously large tubes. Always have tubes ±0.5 mm available.
Q6: During your secondary assessment of a 4-year-old with asthma exacerbation, which finding
indicates progression from respiratory distress to respiratory failure?
A. Increased respiratory rate from 30 to 50 breaths/min
B. Decreased level of consciousness and quiet chest on auscultation [CORRECT]
C. Improved oxygen saturation with supplemental oxygen
D. Presence of accessory muscle use with nasal flaring
Correct Answer: B
Rationale: Respiratory failure is characterized by inadequate gas exchange manifesting as altered
mental status (hypoxemia/hypercapnia affecting brain perfusion) and decreased breath sounds
(indicating fatigue and inadequate air movement). A "quiet chest" in a struggling asthmatic is a pre-
arrest finding. Option A shows increased effort but not failure. Option C indicates improvement. Option
D describes distress, not failure. AHA PALS emphasizes that mental status change and poor air entry are
critical signs of impending respiratory arrest requiring immediate intervention.
