The perinatal nurse has assessed Neela, who has a twin pregnancy, and made the following determinations: blood pressure = 136/80; pulse rate = 84; fetal heart rates (FHRs) are between 138–146 bpm and 132–138 bpm; uterine contractions occur every
5–6 minutes, duration = 45 seconds, moderate strength. Neela's birth plan describes her wish to be involved in all decision-making throughout her labor and birth as well as her partner's wish to say a prayer in each infant's ear as soon after birth as possible (he is a Muslim). The perinatal nurse's appropriate actions would include a discussion with Neela and her partner about: A) The need for Neela to have an intravenous infusion administered throughout labor B) The emergent care the infants will require after birth that will not allow the time to pray C) The need for epidural analgesia during labor because of Neela's multiple gestation D) The gestational abilities of the twins at birth, the progress of Neela's labor and the nurse's ability to advocate for prayers if possible
