A 35-year-old G3P2 woman currently 39 weeks pregnant presents to the emergency department with painful vaginal bleeding shortly after a motor vehicle accident in which she was a passenger. She had her seat belt on and reports that the airbag deployed immediately upon her car's impact against a tree. She admits that she actively smokes cigarettes. Her prenatal workup is unremarkable. Her previous pregnancies were remarkable for one episode of chorioamnionitis that resolved with antibiotics. Her temperature is 98.6°F (37°C), blood pressure is 90/60 mmHg, pulse is 130/min, and respirations are 20/min. The fetal pulse is 110/min. Her uterus is tender and firm. The remainder of her physical exam is unremarkable. What is the most likely diagnosis?
APlacental abruption
BEclampsia
CVasa previa
DPreterm labor
EPreeclampsia
A 26-year-old primigravid woman at 39 weeks' gestation is admitted to the hospital in active labor. Pregnancy was complicated by mild oligohydramnios detected a week ago, which was managed with hydration. Her pulse is 92/min, respirations are 18/min, and blood pressure is 134/76 mm Hg. Pelvic examination shows 100% cervical effacement and 10 cm cervical dilation; the vertex is at 0 station. Cardiotocography is shown. Which of the following is the most appropriate next step in management?
AMaternal repositioning and oxygen administration
BEmergent cesarean section
CElevation of the fetal head
DReassurance
ERapid amnioinfusion
A 35-year-old G1 is brought to the emergency department because of sharp pains in her abdomen. She is at 30 weeks gestation based on ultrasound. She complains of feeling a little uneasy during the last 3 weeks of her pregnancy. She mentions that her abdomen has not been enlarging as expected and her baby is not moving as much as during the earlier part of the pregnancy. If anything, she noticed her abdomen has decreased in size. While she is giving her history, the emergency medicine physician notices that she is restless and is sweating profusely. An ultrasound is performed and her blood is sent for type and match. The blood pressure is 90/60 mm Hg, the pulse is 120/min, and the respiratory rate is 18/min. The fetal ultrasound is significant for no fetal heart motion or fetal movement. Her blood work shows the following: hemoglobin, 10.3 g/dL; platelet count, 1.1*10(5)/ml; bleeding time, 10 minutes; PT, 25 seconds; and PTT, 45 seconds. Which of the following would be the best immediate course of management for this patient?
ALow-molecular-weight heparin
BFresh frozen plasma
CInitiation of labor
DD-dimer assay
