A multipara in latent phase of labor experiences spontaneous rupture of membranes while walking.

Which is the first priority nursing action?

Choice A rationale
Although the placenta acts as a partial barrier, it does not keep out all harmful substances, allowing some to cross and affect fetal development.
Choice B rationale
One of the placenta's early functions is producing hormones like human chorionic gonadotropin (hCG), estrogen, and progesterone, making it act as an endocrine gland.
Choice C rationale
The placenta does not thin out; it remains robust and increases in thickness to support the growing fetus and facilitate nutrient and gas exchange.
Choice D rationale
While optimal blood circulation through the placenta is crucial, this statement lacks detail on the specific structural and functional aspects of the placenta.

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.
