Which statement regarding the role and function of the cervix during pregnancy is true?

Question

Quizplus · Accepted Answer

During pregnancy, the cervix produces thick mucus that plugs the cervical canal and helps prevent bacteria or other pathogens from entering the uterus, which could potentially harm the developing fetus. This mucus plug may be expelled as the cervix begins to dilate during labor, often referred to as the "bloody show," but it does not confirm pregnancy in the first trimester. The EMT may palpate the cervix during labor to assess cervical dilation and effacement, but this is not a function of the cervix during pregnancy itself. While the cervix does play a role in preventing premature birth, it does so by remaining tightly closed and preventing the fetal membranes from rupturing too soon, rather than by constricting.
