Answer to Question 1

Lecithin is a component of surfactant that keeps the alveoli from collapsing with each breath. The sphingomyelin level is higher until the fetal lungs are mature, and then the lecithin level is higher than sphingomyelin. The L/S ratio (lecithin/sphingomyelin) helps predict the maturity of the fetal lungs and the likelihood of fetal survival after birth.

Answer to Question 2

C
Explanation: A) Inferior pertains to the lower section of the body, not a direction.
B) Proximal means moving toward the body where the limb is attached.
C) Correct
D) Superior pertains to the upper section of the body, not a direction.
