A nurse on the obstetric unit is caring for a client who experienced abruptio placentae. The nurse observes petechiae and bleeding around the IV access site. The nurse should recognize that this client is at risk for which of the following complications?

Choice A) Prepare for an emergency cesarean birth is incorrect because this is not a priority or appropriate action for a nurse who is caring for a client who has preeclampsia and is being treated with magnesium sulfate IV.

Preeclampsia is a condition that causes high blood pressure, proteinuria, and edema during pregnancy. It can lead to complications such as eclampsia, which is seizures, or HELLP syndrome, which is hemolysis, elevated liver enzymes, and low platelets. Magnesium sulfate is a medication that helps to prevent or treat seizures in preeclamptic clients by relaxing the muscles and nerves. However, it can also cause side effects such as respiratory depression, hypotension, or loss of reflexes. Preparing for an emergency cesarean birth may be necessary if the client has severe preeclampsia or fetal distress, but it does not address the immediate problem of magnesium toxicity. Therefore, this action should be done only when indicated by the physician and after stabilizing the client's condition.

Choice B) Discontinue the medication infusion is correct because this is a priority and appropriate action for a nurse who is caring for a client who has preeclampsia and is being treated with magnesium sulfate IV. Discontinuing the medication infusion can help to stop or reduce the adverse effects of magnesium sulfate, such as respiratory depression, hypotension, or loss of reflexes. These effects can indicate magnesium toxicity, which is a life-threatening condition that can cause cardiac arrest or coma. The nurse should also notify the physician and prepare to administer calcium gluconate, which is an antidote for magnesium toxicity. Therefore, this action should be done as soon as possible for clients who show signs of magnesium overdose.

Choice C) Place the client in Trendelenburg's position is incorrect because this is not a safe or suitable action for a nurse who is caring for a client who has preeclampsia and is being treated with magnesium sulfate IV.

Trendelenburg's position means lying on the back with the head lower than the feet. It is sometimes used to improve blood flow to the brain or heart in cases of shock or hypotension. However, it can also cause complications such as increased intracranial pressure, decreased lung expansion, aspiration, or acid reflux. Moreover, it does not help to reverse or prevent the side effects of magnesium sulfate, such as respiratory depression, hypotension, or loss of reflexes. Therefore, this action should be avoided or used with caution for clients who are receiving magnesium sulfate IV.

Choice D) Assess maternal blood glucose is incorrect because this is not a relevant or necessary action for a nurse who is caring for a client who has preeclampsia and is being treated with magnesium sulfate IV. Blood glucose is the level of sugar in the blood that provides energy to the cells. It is measured by a blood test or a finger stick test. It can be affected by various factors such as diet, exercise, medication, or pregnancy. Assessing maternal blood glucose may be important for clients who have diabetes or gestational diabetes, which are conditions that cause high blood sugar levels that can harm the mother and the baby. However, it does not relate to preeclampsia or magnesium sulfate, which are conditions that affect blood pressure and nerve function. Therefore, this action should be done only when indicated by the physician and according to the client's history and needs.

Choice A) Increased urinary output: This is not a sign of sepsis in newborns. In fact, sepsis can cause reduced urinary output due to poor blood flow to the kidneys and dehydration.

Choice B) Hypothermia: This is a sign of sepsis in newborns. Sepsis can cause changes in temperature, often fever, but sometimes low temperature. Hypothermia can indicate a severe infection that affects the body's ability to regulate its temperature.

Choice C) Wakefulness: This is not a sign of sepsis in newborns. Sepsis can cause reduced activity and lethargy due to inflammation and organ dysfunction.

Choice D) Interest in feeding: This is not a sign of sepsis in newborns. Sepsis can cause reduced sucking and difficulty feeding due to poor appetite, nausea, vomiting, and abdominal distension.
