A woman at 40 weeks gestation calls the labor unit to see whether or not she should go to the hospital to be evaluated.

Which of the following statements by the woman indicates that she is probably in labor and should proceed to the hospital?

Choice A rationale
The occiput anterior position is optimal for labor and birth due to the fetal head's alignment with the maternal pelvis, reducing resistance and facilitating descent through the birth canal.
Choice B rationale
The occiput posterior position can lead to prolonged labor and increased discomfort because the fetal head does not align with the maternal pelvis as effectively as in the anterior position.
Choice C rationale
The mentum posterior position is uncommon and often requires medical intervention, as the chin-first presentation can obstruct labor progression and prevent the fetus from passing through the birth canal.
Choice D rationale
The occiput transverse position may result in a difficult labor due to the fetal head being oriented sideways, hindering descent and potentially necessitating medical assistance or operative delivery.

Choice A rationale
Calculating from the LMP of February 14, 2019, the estimated date of birth using Naegele's rule would not fall in September.
Choice B rationale
Naegele's rule calculates EDB by adding 7 days to the LMP and then subtracting 3 months. This does not lead to a November date.
Choice C rationale
Using Naegele's rule, adding 7 days to February 14 results in February 21, 2019, then subtracting 3 months, results in November 2019.
Choice D rationale
While close, November 7 is not accurate. Naegele's rule would adjust from February 14, giving an EDB in mid to late November.
