A nurse is assessing a newborn who was born at 42.5 weeks of gestation. Which of the following findings should the nurse expect?

Choice A reason: Preeclampsia is not the correct answer, as it is a hypertensive disorder of pregnancy that causes high blood pressure, proteinuria, and edema. Preeclampsia can be a risk factor for abruptio placentae, which is a premature separation of the placenta from the uterine wall, but it is not a complication of it. Preeclampsia does not cause petechiae or bleeding around the IV access site, but rather headaches, blurred vision, or epigastric pain.

Choice B reason: Anaphylactoid syndrome of pregnancy is not the correct answer, as it is a rare and fatal condition that occurs when the amniotic fluid enters the maternal circulation and causes an allergic reaction. Anaphylactoid syndrome of pregnancy can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Anaphylactoid syndrome of pregnancy would cause respiratory distress, hypotension, or cardiac arrest.

Choice C reason: Puerperal infection is not the correct answer, as it is a bacterial infection of the reproductive tract that occurs after childbirth. Puerperal infection can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Puerperal infection would cause fever, foul-smelling lochia, or pelvic pain.

Choice D reason: Disseminated intravascular coagulation is the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. Disseminated intravascular coagulation can occur as a complication of abruptio placentae, and it is indicated by the petechiae and bleeding around the IV access site. Disseminated intravascular coagulation would also cause a low platelet count, a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.

Choice A reason: To call for an immediate magnesium sulfate level is not the immediate action that the nurse should take, as it is a diagnostic test that requires a blood sample and a laboratory analysis, which can take time and delay the treatment. The nurse should first stop the infusion and notify the provider, as the client is showing signs of magnesium sulfate toxicity, which is a life-threatening condition that can cause respiratory depression, cardiac arrest, or coma.

Choice B reason: To prepare to administer hydralazine is not the immediate action that the nurse should take, as it is a pharmacological intervention that requires a prescription and an assessment of the blood pressure and the fetal status. Hydralazine is an antihypertensive drug that lowers the blood pressure and prevents the complications of severe preeclampsia, such as eclampsia, stroke, or organ damage. However, the client's blood pressure is not very high and is not the main problem at the moment.

Choice C reason: To discontinue the magnesium sulfate infusion is the immediate action that the nurse should take, as it is the first and most important intervention that can reverse the effects of magnesium sulfate and restore the neuromuscular function and the respiratory rate. Magnesium sulfate is a drug that prevents seizures and lowers the blood pressure in clients with severe preeclampsia, but it can also cause toxicity if the dose is too high or the infusion is too fast.

Choice D reason: To administer oxygen is not the immediate action that the nurse should take, as it is a supportive intervention that improves the oxygen delivery to the tissues and organs, but does not address the underlying cause of the respiratory depression, which is the magnesium sulfate toxicity. The nurse should administer oxygen only after stopping the infusion and assessing the oxygen saturation and the respiratory status.
