Case Scenario: AB (gravida 3, para 0) has a history of spontaneous abortion at 10 weeks' gestation and a preterm delivery and demise of a neonate at 21 weeks' gestation. At her 28-week prenatal visit, she reports increased clear vaginal discharge and feelings of pelvic pressure. Examination of her cervix reveals 2-cm dilation and a presenting fetal part low in the pelvis. TA is admitted to the hospital, and uterine activity is documented. Magnesium sulfate therapy is ordered for treatment of preterm labor. The nurse prepares for magnesium sulfate administration by the intravenous route.

Questions:

1. How will magnesium sulfate therapy be initiated? What intervals and dosages should be anticipated?
2. What maternal and fetal side effects will the nurse expect to observe?
