A child with stridor and drooling may have severe upper airway obstruction such as epiglottitis. Attempting to inspect the throat can trigger complete airway closure. The priority is to maintain airway patency and prepare for advanced airway management with appropriate personnel and equipment. Early recognition and rapid preparation for intubation or surgical airway can prevent sudden deterioration and cardiac arrest.

2.

What is the first step in pediatric assessment according to PALS?
A. Secondary survey
B. Primary assessment (ABCDE)
C. Detailed history
D. Lab testing

Correct Answer: B

Explanation:
The PALS systematic approach begins with the primary assessment using the ABCDE method: airway, breathing, circulation, disability, and exposure. This structured evaluation helps providers quickly identify life-threatening conditions and intervene immediately. It ensures that airway and breathing problems are treated first, followed by circulation and neurologic status. Early identification and intervention significantly improve pediatric survival outcomes.

3.

What is the recommended compression-to-ventilation ratio for two-rescuer CPR in children?
A. 30:2
B. 15:2
C. 20:2
D. 10:1

Correct Answer: B

Explanation:
For pediatric patients receiving CPR from two rescuers, the recommended compression-to-ventilation ratio is 15:2. This ratio provides more frequent ventilations compared to adult CPR because most pediatric cardiac arrests are caused by respiratory failure rather than primary cardiac events. Adequate ventilation is critical for oxygenation and preventing further deterioration into cardiac arrest.

4.

Which medication is first-line for pediatric pulseless ventricular tachycardia?
A. Atropine
B. Epinephrine
C. Amiodarone
D. Adenosine

Correct Answer: B

Explanation:
Epinephrine is the first-line medication for pediatric cardiac arrest rhythms, including pulseless ventricular tachycardia and ventricular fibrillation. It improves coronary and cerebral perfusion pressure during CPR by causing vasoconstriction. Early administration every 3–5 minutes during resuscitation enhances the chances of return of spontaneous circulation and improves survival outcomes.

5.

What is the initial fluid bolus for pediatric shock?
A. 5 mL/kg
B. 10 mL/kg
C. 20 mL/kg isotonic crystalloid
D. 50 mL/kg

Correct Answer: C

Explanation:
The recommended initial fluid bolus for pediatric shock is 20 mL/kg of isotonic crystalloid such as normal saline or lactated Ringer’s solution. Rapid fluid administration helps restore intravascular volume and improve perfusion. Reassessment after each bolus is essential to monitor response and avoid fluid overload, especially in cases of cardiogenic shock.

6.

A child has a heart rate of 50/min with poor perfusion despite oxygenation and ventilation. What should you do next?
A. Start chest compressions
B. Administer adenosine
C. Observe
D. Give atropine only

Correct Answer: A

Explanation:
In pediatric patients, bradycardia with poor perfusion is treated aggressively. If the heart rate remains below 60/min despite adequate oxygenation and ventilation, chest compressions should be started immediately. This helps maintain circulation and oxygen delivery to vital organs. Medications such as epinephrine may follow if bradycardia persists.

7.

Which rhythm is most common in pediatric cardiac arrest?
A. Ventricular fibrillation
B. Asystole
C. Atrial flutter
