In the third trimester, mild contractions that mimic early labor are called what?

• A. Henderson-Hasselbach
• B. Braxton-Hicks
• C. Stokes-Adams
• D. Adair-Dighton

Answer: (B)

Mild contractions that resemble early labor in the third trimester are Braxton Hicks contractions. These are the uterus’s practice contractions—usually irregular, often painless, and not aimed at dilating the cervix. They can feel like a tightening across the abdomen and may come and go, sometimes lasting 30 to 60 seconds. Because they don’t progressively strengthen or become more frequent, they don’t advance labor. Dehydration, overexertion, or a full bladder can make them more noticeable, but they typically ease with rest, hydration, or a change in activity. In contrast, true labor contractions become regular, increase in frequency and intensity, and are associated with progressive cervical dilation. If contractions become regular and persistent or are accompanied by other signs like vaginal bleeding or rupture of membranes, medical evaluation is important.
