Explanation
•Considering that the woman has already reached full cervical dilation and already lies at +2 station, the nurse should anticipate caring for the mother at the second stage of labor.
•The presenting part is now below the ischial spines. As the fetal head touches the internal side of the perineum, the perineum begins to bulge and appear tense. The circle enlarges until the fetus is pushed out of the birth canal.
•First stage of labor is incorrect because the first stage of labor starts from onset of regularly perceived uterine contractions and ends with full cervical dilation.
•Third stage of labor, or the placental stage, follows after the expulsion of the infant and ends with the delivery of the placenta.
•The fourth stage of labor is incorrect because the fourth stage follows placental expulsion to 1-4 hours postpartum.
