Which of the following shows a correct sequence of events after atelectasis develops in respiratory distress syndrome of the newborn?
A) Increased pulmonary vascular resistance,atelectasis,hypoperfusion
B) Pulmonary hypoperfusion,hypoxic vasoconstriction,right-to-left shunt
C) Respiratory acidosis,hypoxemia,hypercapnia
D) Right-to-left shunt,hypoxic vasoconstriction,hypoperfusion

Question

Quizplus · Accepted Answer

Atelectasis in respiratory distress syndrome of the newborn can result in decreased oxygenation and perfusion in the lungs. This causes hypoxic vasoconstriction, which in turn leads to pulmonary hypoperfusion. The hypoperfusion can cause blood to bypass the lungs, resulting in a right-to-left shunt. This can lead to systemic hypoxia and acidosis in the newborn.
