In the active phase of labor, what is the expected duration of contractions?

• A. 30-45 seconds
• B. 45-60 seconds
• C. 60-90 seconds
• D. 90-120 seconds

Answer: (B)

In the active phase of labor, women typically experience contractions that last between 45 to 60 seconds. This phase is characterized by more frequent and intense contractions as the body progresses toward delivery. During this stage, contractions serve to dilate the cervix more effectively, and women often perceive these contractions as stronger, which aligns with the expected duration.

The range of 45 to 60 seconds is standard as it reflects a balance between effective uterine activity and allowing time for the fetus to tolerate contractions. Longer durations of contractions can lead to fetal distress, while shorter contractions may not provide sufficient stimulus for cervical dilation.

Understanding this typical timeframe helps healthcare providers assess labor progress and make necessary interventions to support both the mother and the baby throughout the labor process.
