With regard to factors that affect how the fetus moves through the birth canal, nurses should be aware that:
 
  a. The fetal attitude describes the angle at which the fetus exits the uterus.
  b. Of the two primary fetal lies, the horizontal lie is that in which the long axis of the fetus is parallel to the long axis of the mother.
  c. The normal attitude of the fetus is called general flexion.
  d. The transverse lie is preferred for vaginal birth.

Question 2

Which presentation is described accurately in terms of both presenting part and frequency of occurrence?
 
  a. Cephalic: occiput; at least 95 c. Shoulder: scapula; 10 to 15
  b. Breech: sacrum; 10 to 15 d. Cephalic: cranial; 80 to 85

Answer to Question 1

ANS: C
The normal attitude of the fetus is general flexion. The fetal attitude is the relation of fetal body parts to one another. The horizontal lie is perpendicular to the mother; in the longitudinal (or vertical) lie the long axes of the fetus and the mother are parallel. Vaginal birth cannot occur if the fetus stays in a transverse lie.

Answer to Question 2

ANS: A
In cephalic presentations (head first), the presenting part is the occiput; this occurs in 96 of births. In a breech birth, the sacrum emerges first; this occurs in about 3 of births. In shoulder presentations, the scapula emerges first; this occurs in only 1 of births.
