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 39-year-old woman, gravida 5, para 4, at 41 weeks' gestation is brought to the hospital because of regular uterine contractions that started 2 hours ago. Pregnancy has been complicated by iron deficiency anemia treated with iron supplements. Pelvic examination shows the cervix is 90% effaced and 7-cm dilated; the vertex is at -1 station. Fetal heart tracing is shown. The patient is repositioned, O2 therapy is initiated, and amnioinfusion is done. A repeat assessment after 20 minutes shows a similar cervical status, and no changes in the fetal heart tracing, and less than 5 contractions in a period of 10 minutes.What is the most appropriate next step in management?
AEmergent cesarean delivery
BMonitor without intervention
CBegin active pushing
DRetry maternal repositioning
EAdminister tocolytics
A 22-year-old G4P2 at 35 weeks gestation presents to the hospital after she noticed that "her water broke." Her prenatal course is unremarkable, but her obstetric history includes postpartum hemorrhage after her third pregnancy, attributed to a retained placenta. The patient undergoes augmentation of labor with oxytocin and within four hours delivers a male infant with Apgar scores of 8 and 9 at 1 and 5 minutes, respectively. Three minutes later, the placenta passes the vagina, but a smooth mass attached to the placenta continues to follow. Her temperature is 98.6°F (37°C), blood pressure is 110/70 mmHg, pulse is 90/min, and respirations are 20/min. What is the most likely complication in the absence of intervention?
AHypertension
BHemorrhagic shock
CTachypnea
DHeart failure
EHyperthermia
