INTRODUCTION
The American Heart Association (AHA) Pediatric Advanced Life Support (PALS) Provider
Course is a rigorous, evidence-based certification program designed for healthcare
professionals who respond to emergencies in infants and children. This advanced course
builds upon Basic Life Support (BLS) skills and equips providers with the knowledge and
critical thinking skills necessary to recognize and manage pediatric respiratory emergencies,
shock, and cardiopulmonary arrest. The PALS curriculum, updated to reflect the latest
science from the 2025 AHA Guidelines for Cardiopulmonary Resuscitation and Emergency
Cardiovascular Care, emphasizes a systematic approach to pediatric assessment, the
integration of high-performance team dynamics, and the application of proven treatment
algorithms. This exam is a critical assessment for physicians, nurses, paramedics, and other
healthcare professionals seeking PALS provider status or recertification. This comprehensive
question bank has been meticulously crafted to mirror the difficulty, application-level
thinking, and clinical depth of the actual PALS exam. By working through these 200
advanced, scenario-based questions, you will not only solidify your knowledge of essential
pediatric resuscitation concepts but also master the nuanced clinical reasoning required to
excel in the high-stakes environment of pediatric emergencies and pass on your very first
attempt.
CORE DOMAINS TESTED
The AHA PALS exam evaluates candidates across a broad spectrum of knowledge areas
essential for the recognition and management of pediatric medical emergencies. Based on
the official PALS Provider Manual and course curriculum, the core domains tested include:
1. Systematic Approach to Pediatric Assessment: This domain covers the structured
evaluation of a pediatric patient using the Pediatric Assessment Triangle (PAT)—
Appearance, Work of Breathing, and Circulation to the Skin—followed by the Primary
and Secondary Assessments (ABCDE). It includes the identification of respiratory
distress, respiratory failure, and shock states.
2. Respiratory Emergencies: This area tests knowledge of the recognition and
management of respiratory distress and failure, including upper airway obstruction
(e.g., croup, foreign body), lower airway obstruction (e.g., asthma, bronchiolitis), and
lung tissue disease (e.g., pneumonia). It covers appropriate interventions such as
,2
oxygen administration, airway positioning, advanced airway management, and
medication administration.
3. Shock Recognition and Management: This domain focuses on the pathophysiology,
recognition, and treatment of various types of shock in children, including
hypovolemic, distributive (septic, anaphylactic), cardiogenic, and obstructive shock. It
emphasizes rapid fluid resuscitation and the use of vasoactive medications.
4. Cardiac Arrest and Post-Cardiac Arrest Care: This section covers the management of
pediatric cardiac arrest, including high-quality CPR, defibrillation, and the integration
of the Pediatric Cardiac Arrest Algorithm. It also includes the components of post-
cardiac arrest care, such as targeted temperature management and hemodynamic
support.
5. Arrhythmia Management: This domain tests knowledge of the recognition and
management of pediatric bradycardia and tachycardia (narrow and wide complex)
using the PALS Bradycardia and Tachycardia Algorithms. It includes the indications
and dosing for medications like epinephrine, atropine, and amiodarone.
6. Pharmacology and Medication Administration: This area covers the indications,
dosing, and routes of administration for essential pediatric resuscitation medications,
including epinephrine, amiodarone, lidocaine, atropine, magnesium sulfate, and
sodium bicarbonate. It also includes fluid resuscitation volumes and defibrillation
energy doses.
7. Team Dynamics and Effective Resuscitation: This domain emphasizes the
importance of structured communication, clear role assignment, and closed-loop
communication within a resuscitation team to optimize patient outcomes.

Q1: A 2-year-old child is brought to the emergency department with
a barking cough, stridor, and respiratory distress. The child is sitting
upright and drooling. Based on the Pediatric Assessment Triangle
(PAT), which of the following BEST characterizes the child's work of
breathing?
A) Normal, with no visible signs of increased effort.
B) Increased, as evidenced by the audible stridor and abnormal
positioning.
C) Increased, indicated by the presence of drooling alone.
D) Decreased, suggesting impending respiratory failure.
Rationale: The correct answer is B. The PAT assesses Work of
Breathing by observing for abnormal breath sounds (stridor),
abnormal positioning (tripoding or sitting upright), and retractions.
Stridor and sitting upright are clear signs of increased work of
breathing. Option A is incorrect because the child is clearly in distress.
Option C is incorrect because drooling indicates an inability to handle
secretions, which is a sign of airway compromise, but it is not the
primary indicator of increased work of breathing in this context; the
stridor and positioning are. Option D is incorrect because these are
signs of increased, not decreased, work of breathing.
Q2: A 6-month-old infant is found to be unresponsive. You
simultaneously check for breathing and palpate the brachial pulse.
You do not feel a pulse and the infant is not breathing. What is the
correct compression-to-ventilation ratio for a single rescuer
performing CPR on this infant?
A) 15:2
, 4
B) 30:2
C) 15:1
D) 30:1
Rationale: The correct answer is B. For a single rescuer performing
CPR on an infant, the compression-to-ventilation ratio is 30:2. Option
A is incorrect because 15:2 is the ratio for two-rescuer CPR on an
infant. Option C is incorrect because 15:1 is not a standard CPR ratio.
Option D is incorrect because 30:1 is not a standard CPR ratio.
Q3: A 4-year-old child presents with a sudden onset of severe
respiratory distress, absent breath sounds on the left side, and a
deviated trachea to the right. This presentation is MOST consistent
with:
A) Severe asthma exacerbation.
B) A tension pneumothorax.
C) A foreign body aspiration.
D) Bacterial pneumonia.
Rationale: The correct answer is B. A tension pneumothorax is a life-
threatening condition characterized by the accumulation of air in the
pleural space, causing a shift of the mediastinum. This leads to
tracheal deviation away from the affected side, absent breath
sounds, and severe respiratory distress. Option A is incorrect because
asthma typically presents with bilateral wheezing, not unilateral
absent breath sounds. Option C is incorrect because a foreign body
aspiration typically causes localized wheezing or stridor, not a tension
pneumothorax. Option D is incorrect because pneumonia typically
presents with fever and crackles, not acute tracheal deviation.
Q4: A 10-year-old child is in cardiac arrest. The cardiac monitor shows
a shockable rhythm. You deliver a shock. What is the recommended
dose for the first shock in a pediatric patient?
A) 1 J/kg
