Betty's cervix is fully dilated and contractions are strong. Nurse Lee explains to Betty's husband that his wife is in the stage. A. crowning B. effacing C. placental D. transition I think the answer is B

The correct answer is D. transition.

To arrive at this answer, let's briefly review the stages of labor. Labor is typically divided into three stages:

1. Stage 1: This is the longest stage and includes three sub-stages: early labor, active labor, and transition. During early labor, the cervix begins to dilate and efface (thin out). Active labor is marked by stronger contractions and more rapid dilation. The transition is the final part of Stage 1 and is characterized by fully dilated cervix (10 centimeters) and intense contractions.

2. Stage 2: This is the stage of labor when the baby is born. It begins with the fully dilated cervix and ends with the baby's delivery.

3. Stage 3: This stage involves the delivery of the placenta or afterbirth.

In the scenario provided, Betty's cervix is fully dilated, and the contractions are described as strong. These are indications of being in the transition stage. During the transition stage, contractions are usually the most intense and may be accompanied by the urge to push. This stage is a sign that labor is progressing towards the final stage of pushing and delivery.

Taken together, the correct answer is D. transition.
