Answer to Question 1

C
Because the fetal presenting part is positioned high in the pelvis and is not well applied to the cervix, a prolapsed cord could occur if the membranes rupture.

Answer to Question 2

C
A variety of these factors are responsible for initiation of respirations.
The PO2 decreases at birth and the PCO2 increases.
The foramen ovale closes at birth.
Tactile stimuli aid in initiating respirations, but are not the main cause.
