Answer 1

D and B - Infant respiratory distress syndrome is a lack of surfactant production in the lungs. Oxygen would also used untill the infant can produce enough surfactant.

Answer 3

RDS in newborns, especially premies are due to the fact that surfactant is created late in the lungs, the last couple of weeks before birth, So if the baby is premature, it hadn't had time to make surfactant. Surfactant is necessary for your lungs to expand and thereby allowing gas exchange. In my opinion, a doctor would have to do both (B) and (D) because if the infant didn't get O2 it wouldn't have time to live long enough for the surfactant to work.

Answer 4

It is a syndrome caused in premature infants by developmental insufficiency of surfactant production and structural immaturity in the lungs...

I thinks its D.
