PALS POST TEST QUESTIONS AND ANSWERS ALREADY GRADED A+. 100% VERIFIED SOLUTIONS | UPDATED
PER LATEST GUIDELINES | GRADED A+
This examination assesses the essential knowledge and clinical competencies required for Pediatric Advanced Life
Support certification. It evaluates understanding of the systematic approach to pediatric assessment, recognition
and management of respiratory distress and failure, shock recognition and intervention, and cardiac arrest
management according to the latest American Heart Association guidelines. The assessment utilizes a multiple-
choice format with scenario-based questions that test both foundational knowledge and clinical application in
emergency pediatric care. Candidates must demonstrate critical thinking skills, rapid decision-making abilities,
and integration of PALS algorithms into clinical practice. Success on this examination verifies readiness to provide
effective, evidence-based resuscitation and stabilization care to critically ill or injured infants and children. Each
question requires careful analysis and application of PALS principles.
CORE DOMAINS
Systematic Approach to Pediatric Assessment
Recognition and Management of Respiratory Distress and Failure
Recognition and Management of Shock (Hypovolemic, Distributive, Cardiogenic, Obstructive)
Pediatric Cardiac Arrest Algorithms (Pulseless Arrest, Bradycardia, Tachycardia)
High-Quality Cardiopulmonary Resuscitation (CPR) for Infants and Children
Post-Resuscitation Care and Targeted Temperature Management
Vascular Access and Intraosseous Access
, Pharmacology of Resuscitation Medications
Airway Management and Advanced Airway Adjuncts
Team Dynamics and Effective Communication During Pediatric Resuscitation
SECTION ONE
Question 1
A 3-year-old child is brought to the emergency department with a 2-day history of vomiting and diarrhea. The
child is lethargic, has sunken eyes, and capillary refill is 5 seconds. Vital signs are heart rate 160 beats/minute,
blood pressure 68/42 mm Hg, respiratory rate 40 breaths/minute. What type of shock is this patient most likely
experiencing?
A. Distributive shock
B. Cardiogenic shock
C. Hypovolemic shock
D. Obstructive shock
🟢 Correct Answer:
C
🔴 RATIONALE:
Hypovolemic shock is the most common type of shock in children and is frequently caused by fluid losses from
vomiting and diarrhea. The clinical signs of dehydration (sunken eyes, prolonged capillary refill), tachycardia,
and hypotension are consistent with hypovolemic shock. Distributive shock is associated with sepsis,
,anaphylaxis, or neurogenic causes. Cardiogenic shock results from pump failure. Obstructive shock is caused by
conditions such as cardiac tamponade or tension pneumothorax.
Question 2
A nurse is assessing a 4-year-old child using the Pediatric Assessment Triangle. The child has nasal flaring,
intercostal and suprasternal retractions, and is sitting in the tripod position. Which component of the Pediatric
Assessment Triangle is primarily affected?
A. Appearance
B. Work of breathing
C. Circulation to the skin
D. Level of consciousness
🟢 Correct Answer:
B
🔴 RATIONALE:
Nasal flaring, retractions (intercostal and suprasternal), and the tripod position are all signs of increased work of
breathing. The tripod position optimizes the use of accessory muscles to facilitate breathing. Appearance
includes tone, interactivity, consolability, and gaze. Circulation to the skin assesses color and perfusion. While
respiratory distress can affect appearance, the specific findings described directly reflect work of breathing.
Question 3
During a pediatric resuscitation, the team leader is preparing to defibrillate a child in pulseless ventricular
tachycardia. The defibrillator is set to deliver 2 J/kg. After the first shock, the rhythm remains unchanged. What
dose should be used for the second defibrillation attempt?
A. 2 J/kg
B. 4 J/kg
, C. 6 J/kg
D. 8 J/kg
🟢 Correct Answer:
B
🔴 RATIONALE:
The 2020 American Heart Association PALS guidelines recommend that the first defibrillation dose for pediatric
patients be 2 J/kg, and the second and subsequent doses be 4 J/kg or greater, up to a maximum of 10 J/kg or
adult maximum dose. Escalating to 4 J/kg for the second shock is the standard recommendation. Doses should
not remain at 2 J/kg when the first shock is unsuccessful.
Question 4
A 6-month-old infant presents with a heart rate of 260 beats/minute. The rhythm on the monitor shows narrow
QRS complexes with no visible P waves. The infant is pale, mottled, and lethargic. What is the most appropriate
initial intervention?
A. Synchronized cardioversion at 0.5-1 J/kg
B. Adenosine 0.1 mg/kg rapid IV push
C. Vagal maneuvers with ice to the face
D. Amiodarone 5 mg/kg IV over 20 minutes
🟢 Correct Answer:
A
🔴 RATIONALE:
This infant has supraventricular tachycardia (SVT) with signs of hemodynamic instability (pallor, mottling,
lethargy). The appropriate initial intervention for unstable SVT is immediate synchronized cardioversion at 0.5-1
