Active labor lasts on average for a primipara around how many hours?

• A. 1-2 hours
• B. 3-7 hours
• C. 8-10 hours
• D. 12-14 hours

Answer: (B)

Active labor duration for a first-time mother is typically around 3 to 7 hours. During the active phase, contractions become regular and dilation progresses more steadily, usually from about 4 cm to 10 cm. With a dilation rate near 1 cm per hour, moving from 4 cm to full dilation takes roughly six hours, which fits the 3–7 hour range for many primiparas. Times shorter than this are less common for the initial phase, while longer durations (8–14 hours) can occur but are less typical without interventions or atypical labor patterns.
