Section 1: Systematic Approach & Pediatric Assessment (Questions 1–10)
Q1: You arrive at a daycare where a 3-year-old child is sitting upright, leaning forward with the neck
extended (tripod position), drooling, and has inspiratory stridor. The child appears anxious but is alert.
Using the Pediatric Assessment Triangle (PAT), what is your primary concern?
A. Cardiac arrest is imminent; begin CPR immediately
B. Respiratory failure; prepare for immediate intubation
C. Upper airway obstruction with respiratory distress; maintain position of comfort and call for advanced
airway support [CORRECT]
D. Septic shock; begin fluid resuscitation with 20 mL/kg bolus
Correct Answer: C
Rationale: The PAT reveals: Appearance (anxious but alert = good mental status), Work of Breathing
(tripod positioning, stridor, drooling indicate upper airway obstruction), Circulation to Skin (not
mentioned as abnormal). This represents respiratory distress, not failure—mental status is preserved.
The tripod position maintains airway patency; forcing the child supine could worsen obstruction. Option
A is incorrect because the child is alert with adequate perfusion. Option B is incorrect because
respiratory failure would show altered mental status, decreased respiratory effort, or cyanosis. Option D
is incorrect as there are no signs of shock (warm skin, bounding pulses, normal capillary refill would
suggest distributive shock; this presentation is classic for epiglottitis or foreign body upper airway
obstruction).
Q2: A 6-month-old infant is brought to the ED. The PAT shows: decreased muscle tone (floppy), minimal
respiratory effort with occasional gasps, and mottled, cool skin. Heart rate is 45/min. What is the
appropriate immediate intervention?
A. Administer atropine 0.02 mg/kg IV for bradycardia
B. Begin CPR immediately with ventilation and compressions [CORRECT]
,C. Provide high-flow nasal cannula oxygen at 4 L/min
D. Establish IV access and give epinephrine 0.01 mg/kg before starting compressions
Correct Answer: B
Rationale: This infant demonstrates respiratory failure (decreased muscle tone, minimal respiratory
effort, gasping) with bradycardia (HR 45/min) and signs of poor perfusion (mottled, cool skin). Per AHA
PALS Bradycardia Algorithm: HR <60/min with poor perfusion despite oxygenation and ventilation =
begin CPR immediately. Do not delay CPR for medications or advanced airways. Option A is incorrect
because atropine is for vagal-mediated bradycardia with adequate perfusion, not for severe bradycardia
with poor perfusion. Option C is insufficient—this patient needs ventilatory support, not just oxygen.
Option D delays critical CPR; epinephrine is given every 3-5 minutes during CPR, not before.
Q3: Which vital sign parameters indicate that a 2-year-old child is in respiratory failure rather than
respiratory distress?
A. Respiratory rate 50/min with nasal flaring and retractions
B. Respiratory rate 24/min with diminished breath sounds and altered mental status [CORRECT]
C. Respiratory rate 40/min with grunting and head bobbing
D. Respiratory rate 45/min with use of accessory muscles but normal alertness
Correct Answer: B
Rationale: Respiratory failure is characterized by inadequate respiratory effort leading to hypoxemia
and hypercapnia, manifesting as: decreased respiratory rate (normal 2-year-old RR: 24-40/min; 24/min
is low-normal and falling), diminished breath sounds (poor air movement), and altered mental status
(hypoxic/hypercapnic encephalopathy). Options A, C, and D describe respiratory distress—
compensatory increased work of breathing (tachypnea, retractions, grunting, accessory muscle use) with
preserved mental status. The transition from distress to failure occurs when the child can no longer
maintain compensatory mechanisms, leading to respiratory rate decline and mental status changes.
Q4: You are assessing a 5-year-old, 18 kg child using the PAT. The child is irritable but consolable, has
mild intercostal retractions, and pink skin with capillary refill of 2 seconds. Which classification and
intervention are correct?
A. Respiratory failure; prepare for bag-mask ventilation
B. Cardiogenic shock; begin fluid bolus cautiously
C. Respiratory distress with adequate perfusion; provide supplemental O₂ and monitor closely
[CORRECT]
D. Septic shock; aggressive fluid resuscitation 60 mL/kg
, Correct Answer: C
Rationale: PAT Analysis: Appearance (irritable but consolable = adequate mental status/perfusion to
brain), Work of Breathing (mild retractions = increased effort but compensating), Circulation to Skin
(pink, cap refill 2 seconds = adequate perfusion). This is respiratory distress with adequate perfusion—
support with supplemental O₂, position of comfort, and reassess frequently. Option A is incorrect
because failure requires altered mental status, decreased respiratory effort, or cyanosis despite O₂.
Option B is incorrect—no signs of cardiogenic shock (no gallop, no hepatomegaly, normal skin
perfusion). Option D is incorrect—no signs of shock (warm skin, bounding pulses would suggest
distributive; cool skin, weak pulses would suggest hypovolemic/cardiogenic).
Q5: During bag-mask ventilation (BMV) of a 6-month-old infant in respiratory failure, which technique is
CORRECT?
A. Use the E-C clamp technique with C-shaped fingers on the mask and thumb lifting the jaw, ventilate at
40 breaths/min
B. Create a tight seal with the mask, use just enough volume to produce visible chest rise, rate 20-30
breaths/min [CORRECT]
C. Deliver large tidal volumes to ensure adequate ventilation, rate 30-40 breaths/min to compensate for
small tidal volume
D. Perform BMV with one hand while compressing the chest with the other at 15:2 ratio
Correct Answer: B
Rationale: AHA PALS BMV technique: Rate 20-30 breaths/min for infants/children (slower than adults
to allow adequate exhalation and prevent gastric distention), volume sufficient to produce visible chest
rise only (excessive volume causes gastric insufflation, vomiting, aspiration, and reduces functional
residual capacity). The E-C clamp (not C-E) uses the 3rd, 4th, 5th fingers forming an E under the jaw to
lift, while thumb and index finger form a C on the mask. Option A has the rate too high (40/min causes
hyperventilation and reduced cardiac output). Option C causes gastric distention and hypoventilation
despite high rate. Option D describes CPR, not BMV for respiratory failure.
Q6: A 4-year-old child requires endotracheal intubation. The child weighs 16 kg. What is the appropriate
uncuffed endotracheal tube (ETT) size using the age-based formula?
A. 4.0 mm
B. 4.5 mm
C. 5.0 mm [CORRECT]
D. 6.0 mm
Correct Answer: C
