A nurse is caring for a client who is a primigravida, at term, and having contractions but is stating that she is “not really sure if she is in labor or not.” Which of the following should the nurse recognize as a sign of true labor?
A Changes in the cervix
B Station of the presenting part
C Rupture of the membranes
D Pattern of contractions
The Correct answer and Explanation is:
The correct answer is A: Changes in the cervix.
Explanation:
When assessing whether a client is in true labor, several clinical indicators can help differentiate true labor from false labor (Braxton Hicks contractions). One of the most reliable signs of true labor is changes in the cervix.
- Changes in the Cervix: True labor is characterized by progressive cervical changes. This includes cervical effacement (thinning of the cervix) and dilation (opening of the cervix). During true labor, contractions cause the cervix to gradually dilate and efface to prepare for the passage of the fetus through the birth canal. This cervical change is monitored during labor assessments and is a definitive sign that labor is progressing. In contrast, false labor does not usually produce these cervical changes.
- Station of the Presenting Part: While the station of the presenting part (the position of the fetal head in relation to the ischial spines of the maternal pelvis) is important for understanding fetal descent and engagement, it is not as definitive for distinguishing true labor. The station can change during both true and false labor.
- Rupture of the Membranes: Rupture of the membranes (also known as the water breaking) can occur in both true and false labor, though it is more commonly associated with true labor. However, it is not a definitive sign on its own, as membranes can rupture at any time, and in some cases, they may need to be artificially ruptured during labor.
- Pattern of Contractions: In true labor, contractions typically become regular, progressively more intense, and closer together. They also tend to persist and increase in intensity despite changes in position or activity. Although the pattern of contractions is an important aspect of labor, it alone does not confirm true labor without accompanying cervical changes.
Overall, monitoring cervical changes is a crucial assessment tool used by healthcare providers to confirm the onset of true labor, making it the most definitive indicator among the options provided.
