SECTION 1: Recognition and Initial Assessment of the Critically Ill Child
Question 1
A 4-year-old is brought to the emergency department after 2 days of fever, lethargy, and decreased oral intake. On
arrival the child is pale, capillary refill is 4 seconds, and heart rate is 168 beats per minute. The nurse notes that the child
does not cry when an intravenous catheter is inserted. Which finding most strongly indicates compensated shock rather
than irreversible shock at this moment?
A. Blood pressure remains within the normal range for age
B. Capillary refill time exceeds 5 seconds
C. The child is unresponsive to painful stimuli
D. Urine output has been zero for the past 6 hours
Correct Answer: A
Rationale: In pediatric compensated shock, systemic vascular resistance increases to maintain blood pressure despite reduced cardiac
output; therefore a normal blood pressure does not exclude shock. Unresponsiveness and anuria suggest progression toward
uncompensated or irreversible shock, while prolonged capillary refill is consistent with either stage.
Question 2
During rapid assessment of a 9-month-old infant with respiratory distress, the clinician observes nasal flaring, grunting,
and intercostal retractions. The infant’s respiratory rate is 62 breaths per minute and oxygen saturation is 89 % on room
air. Which physiologic principle best explains why these clinical signs appear before frank hypoxemia becomes severe?
A. Infants rely on diaphragmatic breathing and have limited compensatory reserve
B. The infant’s higher metabolic rate produces more carbon dioxide than adults
C. Surfactant deficiency causes alveolar collapse only after prolonged hypoxia
D. Peripheral chemoreceptors are immature and delay the hypoxic drive
Correct Answer: A
Rationale: Infants are preferential diaphragmatic breathers; any increase in work of breathing quickly produces visible retractions and
grunting as compensatory mechanisms. These signs therefore appear early, often while oxygen saturation is still only modestly reduced,
reflecting limited respiratory reserve rather than delayed chemoreceptor response.
Question 3
A 6-year-old with known asthma presents with progressive dyspnea. The team notes that the child is no longer speaking
in full sentences and is using accessory muscles. Peak expiratory flow is 40 % of personal best. Which additional
observation would most urgently change the immediate management priority from standard asthma pathway to
impending respiratory failure?
A. A silent chest with minimal air movement on auscultation
B. Heart rate of 130 beats per minute
C. Mild intercostal retractions that improve with nebulizer treatment
D. Oxygen saturation of 94 % on 2 L nasal cannula
Correct Answer: A
Rationale: A silent chest indicates severe airway obstruction with insufficient airflow to generate wheezes; this finding signals impending
respiratory arrest and requires immediate escalation of care, including preparation for assisted ventilation. Mild retractions or modest
tachycardia are expected in moderate exacerbations and do not by themselves mandate the same urgency.

Question 4
In the pediatric intensive care unit a 2-year-old is being evaluated for possible sepsis. The rapid response team
calculates the Pediatric Early Warning Score (PEWS) and notes an elevated score driven primarily by heart rate and
capillary refill. Which limitation of PEWS systems must the clinician keep in mind when deciding whether to escalate
care?
A. Scores can lag behind rapid clinical deterioration in some children
B. PEWS replaces the need for clinical judgment in all cases
C. A normal PEWS score guarantees the absence of critical illness
D. PEWS has been validated only for children older than 12 years
Correct Answer: A
Rationale: Early-warning scores provide structured data but are not continuous real-time monitors; clinical deterioration can outpace the
scoring interval. Therefore PEWS must be interpreted together with bedside assessment rather than used as a standalone rule-out tool.
Question 5
A previously healthy 3-year-old develops sudden high fever, irritability, and a rapidly progressive purpuric rash. Blood
pressure is 68/40 mm Hg and the child appears mottled. Which laboratory or clinical priority should be addressed within
the first 15 minutes of arrival?
A. Obtain blood cultures and administer broad-spectrum antibiotics
B. Order a complete blood count and coagulation profile before any therapy
C. Perform a lumbar puncture to rule out meningitis before antibiotics
D. Delay fluids until a central venous catheter is placed
Correct Answer: A
Rationale: In suspected meningococcemia or septic shock, early antibiotics and fluid resuscitation are time-critical interventions that
improve survival. Diagnostic procedures such as lumbar puncture must never delay antibiotic administration when the clinical picture is
consistent with invasive bacterial disease.
Question 6
While performing the pediatric assessment triangle on a 14-month-old, the clinician notes a calm appearance, normal
work of breathing, and pink skin color. The parents report that the child has been less interactive than usual for 12 hours.
How should this combination of findings be interpreted?
A. Appearance is abnormal; further focused assessment is required despite normal work of breathing and color
B. The triangle is completely normal and the child can be discharged without further evaluation
C. Only circulation is abnormal because the child is less interactive
D. Work of breathing is the most sensitive component and overrides appearance
Correct Answer: A
Rationale: The pediatric assessment triangle evaluates appearance, work of breathing, and circulation to skin. Abnormal appearance
(decreased interaction) indicates altered mental status or energy level even when the other two components appear normal, and
therefore mandates a more detailed physical and physiologic assessment.
