Answer to Question 1

ANS: A, B, D
The following advantages are associated with a cephalic presentation: the fetal head is usually the largest part of the infant and after the fetal head is born, the rest of the body usually delivers without complications; the fetal head is capable of molding and there is sufficient time during labor and descent for molding of the fetal head to occur; molding helps the fetus to maneuver through the maternal birth passage; and the fetal head is smooth and round, which is the optimal shape to apply pressure to the cervix and to aid in dilation. Breech or malpresentations can lead to umbilical cord prolapse because the presenting part (e.g., a foot) may not totally cover the cervix. The presenting part does not influence effacement.

Answer to Question 2

ANS: A, B, C
Amniotic fluid should be clear and odorless. It may contain white specks and/or fetal hair (lanugo). Yellowish-green tinged fluid may indicate infection or the presence of meconium.
