Answer to Question 1

B
Several pathophysiologic mechanisms operating simultaneously may lead to an increased ventilatory rate: stimulation of peripheral chemoreceptors (hypoxemia), decreased lung complianceincreased ventilatory rate relationship, stimulation of J receptors, pain, anxiety, or fever.

Answer to Question 2

B
Prior to the introduction of exogenous surfactant, pulmonary air leak syndromes commonly occurred in preterm neonates with RDS on mechanical ventilation.
