Answer to Question 1

B
It is mandatory to instill erythromycin ointment into the eyes of all newborns just after birth to prevent ophthalmia neonatorum. This is an inflammation of the newborn's eyes that results from passing through the birth canal when gonorrheal or chlamydia infection is present.

Answer to Question 2

C
By approximately 35 weeks' gestation, the surfactant produced by the alveoli is sufficient in amount (L/S ration of 2:1) to allow the alveoli to remain partially expanded when the newborn begins to breathe at birth.
