PALS INSTRUCTOR CERTIFICATION EXAM 2026/2027
COMPREHENSIVE PRACTICE QUESTIONS & VERIFIED ANSWERS WITH DETAILED
EXPERT RATIONALE
• This expert-reviewed study guide contains 200 practice questions with verified
answers and detailed EXPERT RATIONALEs, designed to simulate the real PALS
Instructor Certification Exam experience and build deep clinical understanding.
• Use this material by reading each question carefully, selecting your answer before
checking the correct option, then studying the EXPERT RATIONALE thoroughly to
reinforce the "why" behind every decision.
1. A 6-year-old child presents with a heart rate of 220 bpm, blood pressure of
70/40 mmHg, altered mental status, and poor perfusion. What is the MOST
appropriate immediate intervention?
A. Administer adenosine 0.1 mg/kg IV
B. Perform a 12-lead ECG
C. Administer oxygen and obtain IV access
D. Perform synchronized cardioversion at 1 J/kg
E. Administer amiodarone 5 mg/kg IV
Correct Answer: D. Perform synchronized cardioversion at 1 J/kg
, EXPERT RATIONALE: This child presents with unstable supraventricular
tachycardia (SVT) with hemodynamic compromise — altered mental status and
hypotension. Per PALS guidelines, unstable tachycardia with a pulse requires
immediate synchronized cardioversion starting at 1 J/kg. Adenosine is appropriate
for stable SVT, not an unstable patient requiring urgent intervention.
2. During a pediatric resuscitation, you identify pulseless ventricular
tachycardia. After delivering the first defibrillation shock, what is the NEXT
immediate action?
A. Check rhythm and pulse immediately
B. Administer epinephrine 0.01 mg/kg IV/IO
C. Resume CPR immediately for 2 minutes
D. Administer amiodarone 5 mg/kg IV
E. Deliver a second shock at double the joules
Correct Answer: C. Resume CPR immediately for 2 minutes
EXPERT RATIONALE: Per PALS protocol, after delivering a defibrillation shock,
CPR should be resumed immediately without pausing to check rhythm or pulse.
The 2-minute CPR cycle allows adequate perfusion and increases the likelihood of
successful conversion. Rhythm and pulse checks occur after the 2-minute cycle is
complete.
3. A 4-year-old child is in respiratory distress with a respiratory rate of 50
breaths/min, SpO₂ of 88%, and audible wheezing. What is the FIRST-line
treatment?
A. Immediate endotracheal intubation
B. Heliox administration
C. Albuterol via nebulization
D. IV magnesium sulfate
,E. Epinephrine IM injection
Correct Answer: C. Albuterol via nebulization
EXPERT RATIONALE: For a child with respiratory distress and wheezing
consistent with bronchospasm or asthma, the first-line PALS treatment is an
inhaled bronchodilator such as albuterol via nebulization. Intubation is a last resort,
and magnesium sulfate and epinephrine are reserved for severe or refractory
cases.
4. What is the correct compression-to-ventilation ratio for a single rescuer
performing CPR on a 3-year-old child?
A. 15:2
B. 5:1
C. 30:2
D. 20:2
E. 10:1
Correct Answer: C. 30:2
EXPERT RATIONALE: Per PALS and AHA guidelines, a single rescuer performing
CPR on a child (1 year to puberty) uses a 30:2 compression-to-ventilation ratio.
When two or more rescuers are present, the ratio changes to 15:2. This ratio
maximizes chest compression time while ensuring adequate ventilation.
5. A child in septic shock has received 60 mL/kg of isotonic crystalloid over 30
minutes without improvement. Blood pressure remains low. What is the
MOST appropriate next step?
A. Administer another 20 mL/kg fluid bolus
B. Obtain a portable chest X-ray
C. Begin vasoactive therapy with dopamine or epinephrine
, D. Administer sodium bicarbonate
E. Perform immediate intubation
Correct Answer: C. Begin vasoactive therapy with dopamine or epinephrine
EXPERT RATIONALE: In PALS management of septic shock, if the child remains
hemodynamically unstable after 40–60 mL/kg of isotonic fluid resuscitation,
vasoactive agents such as dopamine or epinephrine should be initiated. Continued
fluid boluses without vasopressor support in fluid-refractory shock worsen
outcomes and increase risk of pulmonary edema.
6. Which of the following is the MOST reliable method to confirm
endotracheal tube placement in a pediatric patient?
A. Observing bilateral chest rise
B. Auscultating equal breath sounds bilaterally
C. Observing condensation in the ET tube
D. Continuous waveform capnography
E. Chest X-ray confirmation
Correct Answer: D. Continuous waveform capnography
EXPERT RATIONALE: Continuous waveform capnography is the gold standard
and MOST reliable method for confirming and continuously monitoring ET tube
placement in PALS. While clinical signs such as chest rise and breath sounds are
helpful, they can be misleading. Waveform capnography confirms ventilation of the
lungs with each breath.
7. You are managing a child in PEA (pulseless electrical activity). Which of the
following is the MOST critical action?
A. Immediate defibrillation
B. Administer adenosine
