Which stage of labor may last 14 hours or longer?

1. All stages last equally long.

2. The second

3. The first

4. The third

The correct answer is: The first

The first stage of labor is characterized by the onset of contractions and the gradual dilation of the cervix. This stage is typically the longest, often lasting anywhere from several hours to over 14 hours, particularly for first-time mothers. During this stage, the body prepares for delivery as the cervix opens to about 10 centimeters, allowing the baby to move into the birth canal. In contrast, the second stage of labor, which involves pushing and delivery of the baby, usually lasts shorter, averaging from a few minutes to a few hours. The third stage, which involves the delivery of the placenta, is typically even shorter, often completed within 30 minutes after the birth of the baby. Therefore, while all stages of labor are important and can vary greatly in duration, the first stage is specifically known for its potential longevity, making it the correct answer.
