Domain 1: Systematic Pediatric Assessment (12 Questions)
Q1: A 3-year-old child is brought to the emergency department by parents who report
two days of fever and decreased oral intake. Upon initial observation, the child appears
pale with mottled skin, is irritable but consolable, and has rapid breathing with mild
subcostal retractions. Using the Pediatric Assessment Triangle (PAT), which
combination of findings indicates this child is in compensated shock with respiratory
distress?
A. Pink color, normal work of breathing, consolable
B. Pallor, abnormal work of breathing, irritable but consolable [CORRECT]
C. Cyanosis, absent work of breathing, unresponsive
D. Mottled skin, normal work of breathing, inconsolable
Correct Answer: B
Rationale: The Pediatric Assessment Triangle (PAT) consists of three components:
Appearance (muscle tone, interactiveness, consolability, look/gaze, speech/cry), Work
of Breathing (abnormal airway sounds, retractions, positioning, nasal flaring), and
Circulation to Skin (pallor, mottling, cyanosis). This child demonstrates pallor
(circulation), subcostal retractions indicating abnormal work of breathing, and irritable
,but consolable appearance. These findings are consistent with compensated shock
with respiratory distress.
● Option A describes a stable child with normal findings.
● Option C describes a child in decompensated shock and respiratory
failure/arrest.
● Option D incorrectly states "normal work of breathing" when retractions are
present, and "inconsolable" contradicts the scenario.
Performance Note: B+ performers often recognize individual PAT components but
struggle to synthesize them into a complete clinical picture. Master the PAT as a rapid
30-second assessment tool that precedes vital signs—it's designed for immediate
recognition of life-threatening conditions before touching the patient.
Q2: During the primary assessment of a 6-month-old infant in respiratory distress, you
note the heart rate is 165 bpm, respiratory rate 68/min, SpO₂ 88% on room air, and
capillary refill 2 seconds. Which finding during the primary assessment requires the
MOST immediate intervention?
A. Heart rate of 165 bpm
B. Respiratory rate of 68/min
C. SpO₂ of 88% [CORRECT]
D. Capillary refill of 2 seconds
Correct Answer: C
Rationale: The primary assessment follows the ABCDE approach: Airway, Breathing,
Circulation, Disability, Exposure. An SpO₂ of 88% indicates significant hypoxemia
(normal >94% in children) and represents an immediate threat to oxygenation. Per AHA
,PALS guidelines, hypoxemia requires immediate supplemental oxygen and potential
airway intervention.
● Option A: Heart rate 165 bpm is elevated but appropriate for age with respiratory
distress (normal infant HR 100-160).
● Option B: RR 68/min is tachypneic (normal 30-60) but expected with distress; the
problem is oxygenation, not ventilation rate.
● Option D: Capillary refill 2 seconds is at the upper limit of normal (<2 seconds)
but not immediately life-threatening.
Performance Note: B+ performers sometimes prioritize tachycardia or tachypnea over
actual hypoxemia. Remember: hypoxemia kills faster than tachycardia. Always address
oxygenation deficits before focusing on compensatory mechanisms.
Q3: A 4-year-old with suspected sepsis has the following vital signs: HR 142, RR 32, BP
78/42, Temp 38.9°C, SpO₂ 94%. Using the Pediatric Advanced Life Support systematic
approach, which assessment finding during the secondary survey would most
specifically indicate progression from compensated to decompensated shock?
A. Increasing heart rate to 155 bpm
B. Decreased urine output noted on history
C. Altered mental status with lethargy [CORRECT]
D. Widening pulse pressure
Correct Answer: C
Rationale: Decompensated shock is characterized by inadequate tissue perfusion
despite compensatory mechanisms, manifesting as altered mental status (decreased
brain perfusion), hypotension, and worsening metabolic acidosis. While tachycardia (A)
, and decreased urine output (B) occur in both compensated and decompensated shock,
altered mental status specifically indicates failure of compensatory mechanisms.
● Option A: Tachycardia is a compensatory mechanism present in both stages.
● Option B: Oliguria occurs in compensated shock as the body preserves perfusion
to heart and brain.
● Option D: Widening pulse pressure is not characteristic; instead, narrowing pulse
pressure (decreased diastolic) occurs as systemic vascular resistance increases.
Performance Note: B+ performers often rely too heavily on vital sign trends rather than
recognizing end-organ perfusion markers. Mental status changes are the canary in the
coal mine for decompensation—train yourself to assess interactiveness and
consciousness as perfusion indicators.
Q4: [Select-All-That-Apply] During the initial assessment of a 2-year-old with suspected
foreign body aspiration, which findings would indicate complete airway obstruction
requiring immediate intervention? (Select all that apply)
A. Inability to speak or cry [CORRECT]
B. High-pitched inspiratory stridor
C. Paradoxical chest and abdominal movement ("see-saw" breathing) [CORRECT]
D. Weak, ineffective cough or absent cough [CORRECT]
E. Audible wheezing on auscultation
F. Cyanosis [CORRECT]
Correct Answer: A, C, D, F
Rationale: Complete airway obstruction is a life-threatening emergency. Key indicators
include:
