Which assessments are included in the fetal biophysical profile (BPP)? (Select all that apply.)

Choice A reason: Physiological jaundice is not the correct answer, as it is a normal and benign condition that occurs in about 60% of term newborns, and usually appears after the first 24 hours of life. Physiological jaundice is caused by the breakdown of fetal hemoglobin and the immature liver function, and resolves within a few days.

Choice B reason: Maternal cocaine abuse is not the correct answer, as it is a maternal risk factor that can cause various complications in the newborn, such as low birth weight, prematurity, intrauterine growth restriction, or congenital anomalies. Maternal cocaine abuse does not cause jaundice in the newborn, unless it leads to hepatic or renal dysfunction.

Choice C reason: Maternal/newborn blood group incompatibility is the correct answer, as it is a maternal-fetal condition that can cause hemolytic disease of the newborn, which is a severe form of jaundice that can appear within the first 24 hours of life. Maternal/newborn blood group incompatibility occurs when the mother's blood type is Rh negative and the newborn's blood type is Rh positive, or when the mother's blood type is O and the newborn's blood type is A or B. The maternal antibodies cross the placenta and attack the newborn's red blood cells, causing hemolysis, anemia, and hyperbilirubinemia.

Choice D reason: Absence of vitamin K is not the correct answer, as it is a nutritional deficiency that can cause hemorrhagic disease of the newborn, which is a bleeding disorder that can occur within the first week of life. Absence of vitamin K is due to the lack of intestinal flora and the low vitamin K content in breast milk, and can cause bleeding in the skin, mucous membranes, or internal organs. Absence of vitamin K does not cause jaundice in the newborn, unless it leads to hepatic or biliary dysfunction.

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.
