Pediatric Advanced Life Support — Comprehensive Certification Exam
American Heart Association (AHA) • 50 Questions • Cognitive Mix: 30% Recall / 50% Application / 20% Analysis
Format: 70% Scenario-Based • 20% Direct Recall • 10% Rhythm/Case Analysis
This comprehensive 50-question examination is aligned with the 2026–2027 American Heart
Association (AHA) Pediatric Advanced Life Support (PALS) guidelines and certification
requirements. The exam covers eight content domains, ranging from initial pediatric assessment
and recognition of respiratory failure through post–cardiac arrest care, team dynamics, and special
resuscitation scenarios. Each question has been verified for accuracy against current AHA
algorithms and includes a detailed rationale explaining the clinical reasoning, medication dosing,
and algorithm integration required to select the correct answer. The question style emphasizes
scenario-based clinical reasoning to mirror the cognitive demands of real pediatric resuscitation.
Section 1: Pediatric Assessment and Respiratory Failure Recognition
Q1: A 3-year-old child is brought to the emergency department with lethargy and poor eye
contact. The mother reports decreased oral intake for 2 days. Using the Pediatric
Assessment Triangle (PAT), which component is being evaluated when the clinician
observes the child's muscle tone, mental status, and interaction with the environment?
A. Work of Breathing
B. Circulation to Skin
C. Appearance [CORRECT]
D. Breathing Effort
Correct Answer: C
Rationale: The Pediatric Assessment Triangle (PAT) consists of three components: Appearance, Work
of Breathing, and Circulation to Skin. Appearance evaluates muscle tone, mental status, and
interaction with the environment—this corresponds to the "TICLS" mnemonic (Tone, Interactiveness,
Consolability, Look/Gaze, Speech/Cry). Work of Breathing assesses audible sounds, position, and
retractions, while Circulation to Skin evaluates pallor, mottling, and cyanosis. Recognizing lethargy
and poor eye contact as Appearance abnormalities allows rapid identification of a sick child within the
first 30 seconds of evaluation before hands-on examination.

Q2: A 14-month-old infant presents with audible inspiratory stridor, suprasternal
retractions, and nasal flaring. According to the PAT, this finding most specifically indicates
an abnormality in which component, and what is the most likely underlying
pathophysiology?
A. Appearance; central nervous system depression
B. Work of Breathing; increased airway resistance [CORRECT]
C. Circulation to Skin; peripheral vasoconstriction
D. Appearance; metabolic encephalopathy
Correct Answer: B
Rationale: Stridor, retractions, and nasal flaring are objective signs of increased work of
breathing—the second component of the PAT. Stridor localizes to upper airway obstruction
(extrathoracic airway) and reflects turbulent airflow through a narrowed airway. Suprasternal
retractions indicate significant inspiratory effort against increased resistance. The PAT specifically
separates Appearance from Work of Breathing because a child can have abnormal breathing while
maintaining normal appearance (compensated respiratory distress) or can have both abnormal
(respiratory failure). Identifying Work of Breathing abnormalities early prompts escalation from
supportive observation to active airway intervention.
Q3: A 5-year-old child with gastroenteritis presents with pallor, delayed capillary refill (4
seconds), and cool extremities. The PAT component being assessed is "Circulation to Skin."
What is the most appropriate interpretation of these findings?
A. Normal perfusion; no intervention needed
B. Decompensated shock with hypotension
C. Compensated shock with peripheral vasoconstriction [CORRECT]
D. Primary respiratory failure
Correct Answer: C
Rationale: Pallor, delayed capillary refill, and cool extremities reflect peripheral vasoconstriction—the
body's compensatory mechanism to maintain central blood pressure and perfusion to vital organs.
This represents compensated shock: blood pressure is still within normal range for age because
compensatory mechanisms (sympathetic tone, vasoconstriction, tachycardia) are functioning.
Decompensated shock is defined by hypotension and altered mental status from impaired cerebral
perfusion. Recognizing compensated shock early is critical because children can deteriorate rapidly
once compensation fails; up to 50% of blood volume can be lost before hypotension occurs.

Q4: During the primary assessment of an 8-year-old trauma patient, the provider assesses
the airway, confirms breathing is adequate, and palpates a rapid, thready radial pulse.
According to the ABCDE approach, what is the next step in the primary assessment?
A. Perform a focused history using the SAMPLE mnemonic
B. Assess Disability (mental status, glucose, pupils) and Exposure [CORRECT]
C. Begin synchronized cardioversion for unstable tachycardia
D. Reassess the airway with a laryngoscope
Correct Answer: B
Rationale: The primary assessment follows the ABCDE sequence: Airway, Breathing, Circulation,
Disability, Exposure. After A, B, and C are addressed, the provider must assess Disability (AVPU mental
status, pupillary response, blood glucose) and Exposure (remove clothing for full examination while
preventing hypothermia). SAMPLE history is part of the secondary assessment. Synchronized
cardioversion requires identifying an unstable tachyarrhythmia first. The ABCDE sequence ensures
life threats are identified and treated in order of priority—skipping Disability risks missing
hypoglycemia or increased intracranial pressure, both of which are rapidly reversible.
Q5: A 2-year-old child with bronchiolitis has SpO2 of 88% on room air, grunting respirations
at 70/minute, and altered mental status with marked lethargy. Blood gas analysis would
most likely show which combination of findings consistent with respiratory failure?
A. Low PaCO2 with high pH (respiratory alkalosis)
B. High PaCO2 with low pH (respiratory acidosis) and hypoxemia [CORRECT]
C. Normal PaCO2 with metabolic alkalosis
D. Low PaCO2 with metabolic acidosis only
Correct Answer: B
Rationale: Respiratory failure is defined by inadequate oxygenation (hypoxemia), inadequate
ventilation (hypercapnia), or both. A child with altered mental status and grunting at 70
breaths/minute is fatiguing and likely retaining CO2. Hypercapnia (elevated PaCO2) with low pH
(respiratory acidosis) and hypoxemia is the hallmark of ventilatory failure. Earlier in the illness,
hypoxemia alone may drive tachypnea and produce hypocapnia (respiratory alkalosis), but as the
child tires, CO2 rises. Recognizing the transition from compensated distress (low CO2) to failure (rising
CO2) is the critical trigger for initiating positive-pressure ventilation.
