The nurse is teaching a pregnant woman with type 2 diabetes about her diet during pregnancy. Which client statement indicates that the nurse's teaching was successful?

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: This statement is incorrect, as it describes the direct Coombs test, not the indirect Coombs test. The direct Coombs test is performed on the newborn's blood, and it detects the presence of maternal antibodies that have attached to the newborn's red blood cells. The direct Coombs test can help diagnose hemolytic disease of the newborn, which is a condition where the maternal antibodies destroy the newborn's red blood cells, causing anemia and jaundice.

Choice B reason: This statement is incorrect, as it is not the purpose of the indirect Coombs test, but rather a possible complication of hemolytic disease of the newborn. Kernicterus is a severe form of jaundice that occurs when the bilirubin level in the blood is very high, and it can cause brain damage, deafness, or death. Kernicterus can be prevented by treating the jaundice with phototherapy or exchange transfusion.

Choice C reason: This statement is correct, as it describes the indirect Coombs test, which is performed on the mother's blood, and it detects the presence of Rh-positive antibodies that have formed in response to the exposure to the Rh-positive blood of the newborn. The indirect Coombs test can help identify the risk of hemolytic disease of the newborn, and guide the administration of Rh immunoglobulin, which is a medication that prevents the formation of Rh-positive antibodies.

Choice D reason: This statement is incorrect, as it is not possible for the newborn to have Rh-negative antibodies, since the newborn has Rh-positive blood. Rh-negative antibodies are produced by Rh-negative individuals who have been exposed to Rh-positive blood, such as Rh-negative mothers who have Rh-positive newborns. Rh-negative antibodies can cross the placenta and attack the Rh-positive red blood cells of the newborn, causing hemolytic disease of the newborn.
