The nurse is caring for a neonate undergoing phototherapy. What action does the nurse include on the infant's care plan?

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) Missed abortion: This is not the correct obstetric complication for methotrexate treatment. A missed abortion is a type of miscarriage in which the fetus has died but the products of conception are still retained in the uterus. Methotrexate is not used for this condition, as it can cause toxicity and bleeding. The usual treatment options for a missed abortion are expectant management, medical induction, or surgical evacuation.

Choice B) Abruptio placentae: This is not the correct obstetric complication for methotrexate treatment. Abruptio placentae is a condition in which the placenta separates from the uterine wall before delivery, causing bleeding and fetal distress. Methotrexate is not used for this condition, as it can worsen the bleeding and harm the fetus. The usual treatment options for abruptio placentae depend on the severity of the condition and the gestational age, but they may include fluid resuscitation, blood transfusion, tocolysis, or emergency delivery.

Choice C) Unruptured ectopic pregnancy: This is the correct obstetric complication for methotrexate treatment. An ectopic pregnancy is a pregnancy that implants outside of the uterine cavity, usually in the fallopian tube. An unruptured ectopic pregnancy is one that has not caused any bleeding or rupture of the tube. Methotrexate is used for this condition, as it can dissolve the pregnancy tissue and prevent further growth and complications.

Methotrexate is given as an injection and works by inhibiting folic acid metabolism, which is essential for cell division.

Methotrexate is only suitable for patients who have stable vital signs, low levels of human chorionic gonadotropin (hCG), and no fetal heartbeat or cardiac activity detected by ultrasound.

Choice D) Complete hydatidiform mole: This is not the correct obstetric complication for methotrexate treatment. A complete hydatidiform mole is a type of gestational trophoblastic disease in which there is an abnormal proliferation of placental tissue without any fetal development. Methotrexate is not used for this condition, as it can cause resistance and recurrence. The usual treatment option for a complete hydatidiform mole is suction curettage, which removes the molar tissue from the uterus.
