When assessing a woman in the first stage of labor, the nurse recognizes that the most conclusive sign that uterine contractions are effective would be
Dilation of the cervix
the cervical dilation.
During the first stage of labor, the cervix gradually dilates to allow for the passage of the fetus through the birth canal. The effectiveness of uterine contractions in promoting cervical dilation is one of the key parameters that healthcare providers use to assess the progress of labor. The nurse would use vaginal exams to assess the degree of cervical dilation and effacement, as well as the position and station of the baby in the pelvis.
If the cervix is not dilating in response to adequate contractions, this is a sign that labor is not progressing as it should and further interventions may be necessary. In contrast, if the cervix is dilating at an appropriate rate, this is a good indication that the baby is coming down the birth canal and delivery is progressing as it should.
