A nurse is caring for a client who has preeclampsia and is being treated with magnesium sulfate IV. The client's respiratory rate is 10/min and deep-tendon reflexes are absent. Which of the following actions should the nurse take?

Choice A) Increase oral intake of water between feedings is incorrect because this is not a helpful or recommended measure to help reduce the bilirubin in a newborn who is receiving phototherapy. Bilirubin is a yellow pigment that is produced when red blood cells are broken down. It is normally excreted by the liver into bile and then eliminated by the intestines. However, some newborns have high levels of bilirubin in their blood, which can cause jaundice, a condition that makes the skin and eyes look yellow. Phototherapy is a treatment that uses blue light to help break down the bilirubin and make it easier for the liver to process. Increasing oral intake of water between feedings does not have any effect on the bilirubin level, as water does not contain any nutrients or calories that can stimulate the liver or bowel function. Moreover, giving water to a newborn can cause hyponatremia, which is a low level of sodium in the blood that can lead to seizures, brain damage, or death. Therefore, this measure should be avoided or used with caution for newborns who are receiving phototherapy.

Choice B) Wrap the infant in triple blankets to prevent cold stress during phototherapy is incorrect because this is not a safe or appropriate measure to help reduce the bilirubin in a newborn who is receiving phototherapy. Cold stress is a condition that occurs when a newborn loses too much heat and has difficulty maintaining a normal body temperature. It can cause complications such as hypoglycemia, hypoxia, acidosis, or bleeding. Wrapping the infant in triple blankets may seem like a good way to prevent cold stress, but it can actually cause overheating, dehydration, or hyperthermia, which are equally dangerous for the newborn. Moreover, wrapping the infant in blankets can reduce the effectiveness of phototherapy, as it blocks the exposure of the skin to the blue light. Therefore, this measure should be avoided or used with caution for newborns who are receiving phototherapy.

Choice C) How to prepare the newborn for an exchange transfusion is incorrect because this is not a relevant or necessary measure to help reduce the bilirubin in a newborn who is receiving phototherapy. An exchange transfusion is a procedure that involves replacing some of the newborn's blood with donor blood to lower the bilirubin level and prevent brain damage. It is usually reserved for severe cases of jaundice that do not respond to phototherapy or other treatments. Preparing the newborn for an exchange transfusion involves obtaining informed consent from the parents, placing an umbilical venous catheter, monitoring vital signs and blood tests, and administering medications and fluids. However, these steps are not part of routine care for newborns who are receiving phototherapy, and they do not help to reduce the bilirubin level by themselves. Therefore, this measure should be done only when indicated by the physician and explained by the nurse.

Choice D) Increase the frequency of feedings is correct because this is an effective and recommended measure to help reduce the bilirubin in a newborn who is receiving phototherapy. Feeding provides nutrients and calories that can stimulate the liver and bowel function, which are essential for processing and eliminating bilirubin from the body. Feeding also helps to prevent dehydration, which can worsen jaundice and increase the risk of complications.

Feeding can be done by breast milk or formula, depending on the mother's preference and availability. The frequency of feedings should be increased to at least every 2 to 3 hours or on demand, as long as the newborn shows signs of hunger and satisfaction. Therefore, this measure should be encouraged and supported by the nurse for newborns who are receiving phototherapy.

Choice A) Placenta previa is incorrect because this is not a likely complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. It can cause painless, bright red bleeding in the third trimester, especially after intercourse or a pelvic exam. However, it does not cause abdominal pain, as the bleeding is not associated with uterine contractions or separation. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.

Choice B) Incompetent cervix is incorrect because this is not a possible complication for a client who is at 36 weeks of gestation and has gestational hypertension and reports continuous abdominal pain and vaginal bleeding.

Incompetent cervix is a condition where the cervix is weak and unable to hold the pregnancy, leading to premature dilation and delivery. It can cause painless, watery vaginal discharge or spotting in the second trimester, followed by rupture of membranes and labor. However, it does not cause abdominal pain or heavy bleeding, as the cervix does not tear or detach from the uterus. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.

Choice C) Prolapsed cord is incorrect because this is not a common complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Prolapsed cord is a condition where the umbilical cord slips through the cervix and into the vagina before the baby, compressing the cord and cutting off the blood supply and oxygen to the baby. It can cause variable or prolonged fetal heart rate decelerations, visible or palpable cord in the vagina, or fetal distress. However, it does not cause abdominal pain or bleeding, as the cord does not rupture or bleed. Moreover, it is not related to gestational hypertension, which is a condition that causes high blood pressure during pregnancy. Therefore, this response is irrelevant and inaccurate.

Choice D) Abruptio placentae is correct because this is a probable complication for a client who has gestational hypertension and reports continuous abdominal pain and vaginal bleeding. Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery, causing hemorrhage and hypoxia for the mother and the baby. It can cause severe, constant abdominal pain, dark red bleeding, uterine tenderness or rigidity, fetal distress or demise, or maternal shock or coagulopathy. It can be triggered by gestational hypertension, which is a condition that causes high blood pressure during pregnancy and increases the risk of placental abruption by 25%. Therefore, this response is relevant and accurate.
