During pregnancy, many changes occur as a direct result of the presence of the fetus. Which of these adaptations meet this criterion? (Select all that apply.)

Correct Answer: B

Rationale: The correct answer is B: Development of the operculum. This adaptation refers to the formation of a mucus plug in the cervix during pregnancy, which helps protect the fetus from infections. It is a direct result of the presence of the fetus as it serves as a physical barrier. A: Leukorrhea is the increased vaginal discharge during pregnancy, but it is not a direct result of the fetus presence. C: Quickening is the first fetal movements felt by the mother, but it is a fetal activity, not a direct adaptation. D: Ballottement is a palpation technique used to assess the fetus position, not an adaptation directly caused by the fetus.
