Question 1

What is the recommended tidal volume for neonatal mechanical ventilation using lung-protective strategy?

Accepted Answer

4–6 mL/kg IBW

Answer

Neonatal lung-protective ventilation targets tidal volumes of 4–6 mL/kg IBW to minimize volutrauma in the immature, surfactant-deficient lung.

Question 2

Bronchopulmonary dysplasia (BPD) in premature infants is most associated with:

Accepted Answer

Prolonged mechanical ventilation and oxygen exposure in preterm lungs

Answer

BPD results from mechanical ventilation-induced barotrauma/volutrauma and oxygen toxicity in the immature lung, causing abnormal alveolar and vascular development.

Question 3

In pediatric resuscitation, what is the correct compression-to-ventilation ratio for two-rescuer CPR?

Accepted Answer

15:2

Answer

Two-rescuer pediatric CPR uses a 15:2 ratio to provide more frequent ventilations, as pediatric arrests are more often respiratory in origin.

Question 4

Which inhaled medication is first-line for acute bronchiolitis in a hospitalized infant?

Accepted Answer

Supportive care with nasal suctioning and hydration (no bronchodilators)

Answer

Current AAP guidelines recommend only supportive care for bronchiolitis; bronchodilators, corticosteroids, and antibiotics are not routinely recommended.

Question 5

What is the correct ETT size formula for uncuffed tubes in pediatric patients older than 1 year?

Accepted Answer

Age/4 + 4

Answer

The formula (Age/4) + 4 estimates uncuffed ETT size in children over 1 year, though cuffed tubes are increasingly preferred in modern practice.
