Final answer:
An android pelvis can make labor and delivery more difficult, potentially necessitating a Caesarian section. If the cervix doesn't dilate and labor doesn't progress as it should, medical interventions might be needed. Devin's case of intact mucous plug and no dilation indicated she was not in active labor.
Step-by-step explanation:
The nurse clarifies to a primigravida that her pelvis is of the android type, which usually means the delivery will be more challenging. An android pelvis is a male-like pelvis, which is not as well adapted for childbirth as the female gynecoid pelvis, due to a more heart-shaped pelvic brim, narrower subpubic angle, and smaller pelvic inlet and outlet. This anatomical difference can potentially lead to a more difficult labor process, often requiring medical intervention such as a Caesarian section to safely deliver the baby.
When a woman is in labor, the progression through the stages of labor is essential. During the first stage of labor, the cervix thins and begins to dilate. If labor does not progress, leading to the full dilation of the cervix and eventually to the delivery of the baby and the placenta, medical interventions like administration of pitocin or a Caesarian section may be warranted. Devin's situation, with intact mucous plug and no cervical dilation, signifies that she is likely experiencing pre-labor contractions rather than active labor, and thus was advised to return home.
