What is a common characteristic of Braxton Hicks contractions?

• A. They indicate the onset of labor.
• B. They may occur throughout the pregnancy.
• C. They are always painful.
• D. They require immediate medical attention.

Answer: (B)

Braxton Hicks contractions are a type of sporadic uterine contraction that can occur during pregnancy as the body prepares for labor. One common characteristic of these contractions is that they may occur throughout the pregnancy, often starting in the second trimester and becoming more noticeable as the pregnancy progresses. These contractions are often described as "practice" contractions because they help tone the uterine muscle and prepare for the actual labor process, but they are not a sign that labor is imminent.

This characteristic helps to differentiate Braxton Hicks contractions from true labor contractions, which are regular, painful, and signify that the body is entering labor. While they can sometimes be uncomfortable, they are typically not painful, and they do not require any medical attention unless there are other concerning symptoms.
