Correct Answer is B
Explanation
a. A woman at 37 weeks' gestation who experienced spontaneous rupture of membranes 30 minutes ago with normal fetal movements is not a priority assessment as long as there are no signs of fetal distress.
b. A woman who is 9 cm dilated and fully effaced and is requesting to go to the bathroom to have a bowel movement is in the second stage of labor, which means that the cervix is fully dilated and the fetus is descending in the birth canal.
