Answer to Question 1

B
PG is the second most abundant phospholipid in surfactant. The absence of PG in amniotic fluid would indicate immature lungs, as would be the case in a neonate with RDS. The presence of PG would indicate mature lungs with surfactant.

Answer to Question 2

C
When an abscess is near the pleural surface, the inflamed membranes rub together. The sound produced is heard through a stethoscope and called a pleural friction rub.
