Pediatric Advanced Life Support (PALS) Certification Exam
Verified Questions, Correct Answers, and Detailed
Explanations for Computer Science Students||Already
Graded A+
1. What is the recommended compression-to-ventilation ratio for a
single rescuer performing CPR on a child?
A. 15:2
B. 30:2
C. 15:1
D. 30:1
Rationale: For single-rescuer pediatric CPR, the recommended
compression-to-ventilation ratio is 30:2, aligning with adult
guidelines to maintain adequate perfusion.
2. What is the first medication to consider in pediatric pulseless
ventricular tachycardia?
A. Amiodarone
B. Epinephrine
C. Lidocaine
D. Adenosine
Rationale: Epinephrine is administered every 3–5 minutes during
pulseless VT as it increases coronary and cerebral perfusion.
3. During CPR, what is the recommended depth of chest
compressions for a child?
A. 1 inch (2.5 cm)
B. 1.5 inches (4 cm)
C. At least 2 inches (5 cm)
D. 3 inches (7.5 cm)
Rationale: Compressions should be at least 1/3 the anterior-posterior
diameter of the chest, roughly 2 inches for a child, to ensure effective
circulation.
,4. Which rhythm is considered shockable in pediatric cardiac
arrest?
A. Asystole
B. Pulseless electrical activity (PEA)
C. Ventricular fibrillation (VF)
D. Sinus bradycardia
Rationale: Shockable rhythms include VF and pulseless VT. Asystole
and PEA require CPR and medications, not defibrillation.
5. What is the preferred IV/IO dose of epinephrine for a child in
cardiac arrest?
A. 0.01 mg/kg
B. 0.1 mg/kg
C. 0.01 mg/kg
D. 0.1 mg
Rationale: Epinephrine is administered at 0.01 mg/kg IV/IO every 3–5
minutes during pediatric cardiac arrest.
6. What is the primary cause of pediatric cardiac arrest?
A. Arrhythmias
B. Respiratory failure or shock
C. Myocardial infarction
D. Stroke
Rationale: Most pediatric cardiac arrests result from respiratory
failure or shock leading to hypoxia, unlike adults where cardiac
causes predominate.
7. For a child with bradycardia and poor perfusion, what is the first
intervention?
A. Atropine
B. CPR if inadequate perfusion
C. Epinephrine
D. Defibrillation
, Rationale: Bradycardia with signs of poor perfusion requires
immediate CPR while assessing underlying causes.
8. What is the recommended defibrillation dose for pediatric
VF/pulseless VT?
A. 1–2 J/kg
B. 2–4 J/kg
C. 4–6 J/kg
D. 10 J/kg
Rationale: Initial defibrillation for children is 2–4 J/kg, increasing to 4
J/kg for subsequent shocks if needed.
9. Which airway device is preferred for a child in respiratory arrest
with an unprotected airway?
A. Nasopharyngeal airway
B. Oropharyngeal airway
C. Bag-mask ventilation
D. Laryngeal mask airway
Rationale: Bag-mask ventilation is the primary method to provide
oxygenation in pediatric patients before advanced airway placement.
10. What is the rate of chest compressions during pediatric CPR?
A. 60–80 per minute
B. 80–100 per minute
C. 100–120 per minute
D. 120–140 per minute
Rationale: Compressions should be delivered at 100–120/min to
maintain adequate perfusion.
11. Which is the first step in pediatric advanced airway
management?
A. Intubation
B. Assessment and ventilation with bag-mask
C. Suctioning
