A+ Latest Version
Section 1: Introduction
This comprehensive document provides 150 carefully curated, high-yield practice questions modeled
directly after the American Heart Association (AHA) Pediatric Advanced Life Support (PALS) Exam. Fully
updated to reflect the latest 2026/2027 official guidelines, this master resource is organized into three
progressive, 50-question learning batches to ensure thorough retention and self-assessment.
Inside, you will find vital clinical coverage tracking core resuscitation pillars: advanced pediatric
assessments, critical airway and respiratory failure troubleshooting, targeted fluid and vasoactive shock
management, shockable and non-shockable cardiac arrest algorithms, emergency medication dosing
metrics, rhythm identification, and high-performance team dynamics. Each question is paired with a 100%
verified correct answer and an in-depth clinical rationale, making this premium A+ graded preparatory tool
ideal for nurses, paramedics, respiratory therapists, and physicians aiming for flawless initial certification or
rapid recertification.
The American Heart Association (AHA) Pediatric Advanced Life Support (PALS) exam
1. What is the correct compression-to-ventilation ratio for 2-rescuer infant CPR?
A) 30:2
B) 15:2
C) 15:1
D) 5:1
Explanation: The PALS guidelines dictate that when two healthcare providers are
,performing CPR on an infant or child, the ratio changes from 30:2 to 15:2 to optimize
ventilation frequencies.
2. You are assessing an unresponsive infant who is not breathing but has a central
pulse of 54 bpm with signs of poor perfusion. What is your immediate next step?
A) Give rescue breaths at 1 breath every 2 to 3 seconds.
B) Start high-quality chest compressions.
C) Administer IV Adenosine immediately.
D) Transport the infant immediately without interventions.
Explanation: In pediatric advanced life support, if a child's heart rate is less than 60 bpm
with signs of poor perfusion despite adequate oxygenation and ventilation, you must initiate
chest compressions.
3. What is the recommended depth of chest compressions for an infant during CPR?
A) At least 2 inches (5 cm)
B) About 1.5 inches (4 cm)
C) At least 2.5 inches (6 cm)
D) About 1 inch (2.5 cm)
Explanation: For infants (under 1 year of age), the compression depth should be
approximately one-third the anterior-posterior diameter of the chest, which equates to about
1.5 inches or 4 centimeters.
,4. Which component of the Pediatric Assessment Triangle (PAT) evaluates the child's
neurological status and general alertness?
A) Work of breathing
B) Circulation to skin
C) Appearance
D) Airway patency
Explanation: The Appearance component of the PAT assesses the child's muscle tone,
interactivity, consolability, look/gaze, and speech/cry to quickly gauge central nervous
system function.
5. A 4-year-old child presents with stridor, a barking cough, and retractions at rest.
Which respiratory condition do these signs most strongly indicate?
A) Lower airway obstruction
B) Lung tissue disease
C) Upper airway obstruction
D) Disordered control of breathing
Explanation: Stridor is a high-pitched inspiratory sound characteristic of an upper airway
obstruction, such as croup or foreign body airway obstruction.
6. What is the preferred fluid and initial volume dose for a pediatric patient in
hypovolemic shock?
, A) 5% Dextrose in water, 10 mL/kg
B) Isotonic crystalloid (e.g., Normal Saline), 20 mL/kg
C) Lactated Ringer's, 5 mL/kg
D) Packed red blood cells, 20 mL/kg
Explanation: The standard PALS initial fluid resuscitation for shock is a 20 mL/kg bolus of
an isotonic crystalloid, administered over 5 to 20 minutes.
7. During CPR on a 6-year-old child, an advanced airway is placed. What is the
correct ventilation rate?
A) 1 breath every 5 to 6 seconds
B) 1 breath every 2 to 3 seconds
C) 1 breath every 1 to 2 seconds
D) 2 breaths after every 15 compressions
Explanation: Once an advanced airway is in place, compressions are continuous, and
ventilations are given asynchronously at a rate of 1 breath every 2 to 3 seconds (20 to 30
breaths per minute).
8. Which of the following is a sign of lung tissue disease (such as pneumonia or
pulmonary edema)?
A) High-pitched stridor on inspiration
B) Gunting and decreased oxygen saturation on room air
