The difference between physiological and nonphysiological jaundice is that nonphysiological jaundice

Choice A: This is the correct answer because a hard and tender abdomen is a sign of concealed hemorrhage, which can lead to hypovolemic shock and fetal distress. The nurse needs to monitor the woman's blood loss, blood pressure, pulse, and fetal heart rate to detect any complications and intervene accordingly.

Choice B: This is incorrect because opioid pain medication can mask the signs of shock and fetal distress, and may also cause respiratory depression in both the mother and the fetus. Pain relief should be given after assessing the woman's condition and consulting with the physician.

Choice C: This is incorrect because documenting the findings is not a priority action. The nurse needs to act quickly to prevent further blood loss and fetal compromise, and report the findings to the physician.

Choice D: This is incorrect because relaxation techniques may not be effective in reducing the pain and anxiety caused by abruptio placentae. The nurse should provide emotional support and reassurance to the woman, but also focus on assessing and managing her physical condition.

Choice A: This is incorrect because preeclampsia is a condition characterized by hypertension, proteinuria, and edema that occurs after 20 weeks of gestation. It is not related to abruptio placentae, which is the premature separation of the placenta from the uterine wall. Preeclampsia does not cause petechiae or bleeding around the IV site, but it may cause headache, blurred vision, epigastric pain, or seizures.

Choice B: This is incorrect because anaphylactoid syndrome of pregnancy, also known as amniotic fluid embolism, is a rare and life-threatening complication that occurs when amniotic fluid enters the maternal circulation and triggers an allergic reaction. It is not related to abruptio placentae, but it may occur during labor, delivery, or shortly after birth. Anaphylactoid syndrome of pregnancy does not cause petechiae or bleeding around the IV site, but it may cause respiratory distress, hypotension, cardiac arrest, or disseminated intravascular coagulation.

Choice C: This is the correct answer because disseminated intravascular coagulation (DIC) is a condition in which the blood clotting system is activated abnormally, leading to excessive clot formation and consumption of clotting factors and platelets. This results in bleeding from various sites, such as the IV site, gums, nose, or vagina. DIC is a common complication of abruptio placentae, as the release of thromboplastin from the placenta triggers the clotting cascade. DIC can also cause organ failure, shock, or death if not treated promptly.

Choice D: This is incorrect because puerperal infection, also known as postpartum infection, is a bacterial infection that affects the uterus, vagina, bladder, or wound site after childbirth. It is not related to abruptio placentae, but it may occur due to prolonged labor, cesarean delivery, retained placenta, or poor hygiene. Puerperal infection does not cause petechiae or bleeding around the IV site, but it may cause fever, malaise, foul-smelling lochia, or pelvic pain.
