Concerning the turns and other adjustments of the fetus during the human birth process, known as the mechanism of labor, nurses should be aware that:
1. the seven critical movements must progress in a more or less orderly sequence.
2. asynclitism is sometimes achieved by means of the Leopold maneuver.
3. the effects of the forces determining descent are modified by the shape of the woman's pelvis and the size of the fetal head.
4. at birth the baby is said to achieve "restitution," that is, a return to the C shape of the womb.

1. Incorrect. The seven identifiable movements of the mechanism of labor occur in combi-nations simultaneously, not in precise sequence.
2. Incorrect. Asynclitism is the deflection of the baby's head; the Leopold maneuver is a way to judge descent by palpation of the mother's abdomen.
3. Correct. The size of the maternal pelvis and the fetal head's capacity to mold also affect the process.
4. Incorrect. Restitution is the rotation of the baby's head after it is born.
