Update 2026 | 100% PASS
1.
A 6-year-old is unresponsive and not breathing normally. What is your first action?
A. Check pulse for 2 minutes
B. Start chest compressions
C. Give oxygen by mask
D. Obtain IV access
Answer: B
Rationale: In PALS, if the child is unresponsive and not breathing normally with no pulse
confirmed within 10 seconds → start CPR immediately.
2.
Compression-to-ventilation ratio for 1 rescuer CPR in a child is:
A. 15:2
B. 30:2
C. 5:1
D. 10:1
Answer: B
Rationale: Single rescuer CPR uses 30:2 for all ages except newborns.
3.
Compression-to-ventilation ratio for 2-rescuer child CPR is:
A. 15:2
B. 30:2
C. 5:1
D. 10:2
,Answer: A
Rationale: Two-rescuer CPR in pediatrics uses 15:2 for better ventilation support.
4.
Correct chest compression depth in a child:
A. 1 inch
B. 1.5 inches
C. At least 1/3 chest depth (~2 inches)
D. Full chest collapse
Answer: C
Rationale: Adequate depth ensures perfusion without injury.
5.
A pulse check in a child should not exceed:
A. 5 seconds
B. 10 seconds
C. 20 seconds
D. 30 seconds
Answer: B
Rationale: Delays in CPR reduce survival.
6.
First-line treatment for symptomatic bradycardia in children:
A. Epinephrine
B. Atropine
C. Amiodarone
D. Adenosine
Answer: B
Rationale: Atropine increases heart rate in vagal-related bradycardia.
,7.
Most common cause of cardiac arrest in children is:
A. Myocardial infarction
B. Respiratory failure
C. Stroke
D. Arrhythmia
Answer: B
Rationale: Pediatric arrests are usually respiratory in origin.
8.
Initial oxygen delivery for a child in respiratory distress:
A. Room air
B. Non-rebreather mask
C. Nasal cannula
D. No oxygen
Answer: B
Rationale: High-flow oxygen is needed for severe distress.
9.
A child has no pulse and is apneic. What rhythm is most likely?
A. VF
B. PEA
C. Asystole
D. SVT
Answer: C
Rationale: Pediatric arrests often present as asystole.
10.
Shock is defined as:
A. High blood pressure
B. Inadequate tissue perfusion
, C. Fever
D. Bradycardia
Answer: B
Rationale: Shock = poor organ perfusion.
11.
Most common type of shock in children:
A. Cardiogenic
B. Hypovolemic
C. Neurogenic
D. Obstructive
Answer: B
Rationale: Dehydration and fluid loss are most common causes.
12.
Sign of compensated shock:
A. Hypotension
B. Bradycardia
C. Tachycardia
D. Cyanosis
Answer: C
Rationale: Tachycardia is early compensation.
13.
Late sign of shock in children:
A. Tachycardia
B. Hypotension
C. Anxiety
D. Fever
Answer: B
Rationale: Hypotension indicates decompensated shock.
