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.
Rupture of the membranes.
B.
Pattern of contractions.
C.
Changes in the cervix.
D.
Station of the presenting part.
The Correct Answer and Explanation is:
The correct answer is C. Changes in the cervix.
Explanation:
True labor is characterized by specific physiological changes that distinguish it from false labor or Braxton Hicks contractions. The key sign of true labor is cervical changes, which include both dilation (opening) and effacement (thinning) of the cervix.
- Cervical Changes: In true labor, the cervix undergoes progressive changes due to the rhythmic contractions of the uterus. The cervix begins to dilate (open) and efface (thin out). This is the most definitive sign that labor is progressing. The cervix may go from being long and closed to fully dilated (10 cm) and fully effaced, allowing the baby to pass through the birth canal.
- Rupture of Membranes (Option A): While the rupture of membranes, commonly referred to as “water breaking,” can indicate that labor is imminent or has started, it is not a definitive sign of true labor. Some women may experience the rupture of membranes before labor contractions begin, while others may not have their membranes rupture until well into active labor. Therefore, it is not solely indicative of true labor.
- Pattern of Contractions (Option B): True labor contractions are typically regular, become progressively stronger, last longer, and occur closer together over time. However, some women experience false labor, where contractions may be irregular and do not lead to cervical changes. Thus, while a pattern of contractions can suggest true labor, it is not as definitive as cervical changes.
- Station of the Presenting Part (Option D): The station refers to the position of the baby’s head (or presenting part) in relation to the pelvis. While this is important in assessing labor progress, it is not a definitive sign of true labor. The station of the presenting part can change as labor progresses, but it is not necessarily indicative of whether true labor has begun.
In conclusion, while various signs and symptoms may suggest that labor is beginning, the cervical changes are the most reliable and definitive indicator of true labor. The nurse should assess the cervix for dilation and effacement to confirm that the client is indeed in true labor. This assessment helps ensure that the appropriate interventions and care are provided as labor progresses.
