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. - Answer c. The normal attitude of
the fetus is called general flexion.

diameter.

13. In relation to primary and secondary powers, the maternity nurse comprehends that:
a. Primary powers are responsible for effacement and dilation of the cervix.
b. Effacement generally is well ahead of dilation in women giving birth for the first time;
they are closer together in subsequent pregnancies.
c. Scarring of the cervix caused by a previous infection or surgery may make the
delivery a bit more painful, but it should not slow or inhibit dilation.
d. Pushing in the second stage of labor is more effective if the woman can breathe
deeply and control some of her involuntary needs to push, as the nurse directs. -
Answer a. Primary powers are responsible for effacement and dilation of the cervix
14. While providing care to a patient in active labor, the nurse should instruct the
woman that:
a. The supine position commonly used in the United States increases blood flow.
b. The all fours position, on her hands and knees, is hard on her back.
c. Frequent changes in position will help relieve her fatigue and increase her comfort.
d. In a sitting or squatting position, her abdominal muscles will have to work harder -
Answer c. Frequent changes in position will help relieve her fatigue and increase her
comfort.
15. Which description of the four stages of labor is correct for both definition and
duration?
a. First stage: onset of regular uterine contractions to full dilation; less than 1 hour to 20
hours
b. Second stage: full effacement to 4 to 5 cm; visible presenting part; 1 to 2 hours
c. Third state: active pushing to birth; 20 minutes (multiparous women), 50 minutes

First stage: onset of regular uterine contractions to full dilation; less than 1 hour to 20
hours

womans pelvis and the size of the fetal head.

womb). - Answer c. The effects of the forces determining descent are modified by the

relieve fetal hypoxia.
