A nurse is caring for a client who is 5 hr postpartum following a vaginal birth of a newborn weighing 11 lb 6 oz. (5160 g). The nurse should recognize that this client is at risk for which of the following postpartum complications?

Choice A reason: Initiation of pushing is not an appropriate nursing action, as it can increase the bleeding and the risk of placental separation, which can cause fetal hypoxia, hemorrhage, or shock. Pushing is contraindicated in clients with placenta previa, which is a condition where the placenta covers the cervical opening and can cause painless, bright red bleeding in the third trimester.

Choice B reason: Examination to determine cervical status is not an appropriate nursing action, as it can cause trauma and perforation of the placenta, which can lead to severe bleeding and infection. Examination is contraindicated in clients with placenta previa, unless it is confirmed by ultrasound that the placenta is not low-lying or covering the cervix.

Choice C reason: Preparation for cesarean birth is an appropriate nursing action, as it is the preferred mode of delivery for clients with placenta previa, especially if the bleeding is heavy, the fetus is mature, or the fetal distress is present. Cesarean birth can prevent the complications of placenta previa, such as fetal hypoxia, hemorrhage, or shock.

Choice D reason: A magnesium sulfate infusion is not an appropriate nursing action, as it is a drug that prevents seizures and lowers the blood pressure in clients with severe preeclampsia, which is a hypertensive disorder of pregnancy. Magnesium sulfate is not indicated for clients with placenta previa, unless they also have severe preeclampsia or eclampsia.

Choice A reason: Uterine enlargement greater than expected for gestational age is not a typical manifestation of ectopic pregnancy, because the embryo is implanted outside the uterus, usually in the fallopian tube. The uterus may be slightly enlarged due to hormonal changes, but not more than expected for the gestational age.

Choice B reason: Unilateral, cramp-like abdominal pain is a common manifestation of ectopic pregnancy, because the embryo grows and stretches the fallopian tube, causing inflammation and irritation. The pain may be mild or severe, depending on the size and location of the ectopic pregnancy, and may radiate to the shoulder or back.

Choice C reason: Severe nausea and vomiting is not a specific manifestation of ectopic pregnancy, because it can be caused by other conditions, such as hyperemesis gravidarum, gastroenteritis, or appendicitis. The client may have mild nausea and vomiting due to hormonal changes, but not more than usual for the gestational age.

Choice D reason: Large amount of vaginal bleeding is not a usual manifestation of ectopic pregnancy, because the bleeding is usually internal, into the abdominal cavity. The client may have spotting or light bleeding due to the detachment of the endometrium, but not heavy or profuse bleeding.
