A 42-year-old woman presents to the emergency department in active labor. She has had no prenatal care and is unsure of the gestational age. Labor progresses rapidly and spontaneous vaginal delivery of a baby boy occurs 3 hours after presentation. On initial exam, the child is 1.9 kg (4.2 lb) with a small head and jaw. A sac-like structure containing intestine, as can be seen in the picture, protrudes from the abdominal wall. What complication is closely associated with this presentation?
ALack of abdominal wall muscles
BDehydration and necrosis of bowel
CDuodenal atresia
DTwisting of the bowel around itself
ECardiac defect
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 31-year-old G3P0 is admitted to the hospital with profuse vaginal bleeding and abdominal pain at 34 weeks gestation. She reports passing bright blood with clots and no water in the discharge. She denies recent trauma or medical illnesses. She had no prenatal care. Her previous pregnancies culminated in spontaneous abortions in the second trimester. She has a 6-year history of drug abuse and cocaine smoking 2 hours prior to the onset of her symptoms. Her blood pressure is 160/90 mm Hg, the heart rate is 93/min, the respiratory rate is 19/min, and the temperature is 36.9℃ (98.4℉). The fetal heart rate is 110/min. On examination, the patient is lethargic. Her pupils are constricted, but reactive to light bilaterally. There are no signs of trauma. Abdominal palpation identifies lower abdominal tenderness and strong uterine contractions. The fundus of the uterus is between the xiphoid process and umbilicus. The patient’s perineum is grossly bloody. On pelvic examination, the vaginal canal is without lesions. The cervix is almost completely effaced and 2 cm dilated. Which of the following options is the most likely cause of the patient’s pregnancy-related condition?
AThrombosis of the placental vessels
BDramatic decrease in thrombocytes
CPremature rupture of the membranes
DRupture of the placental vessels
EAbrupt constriction of maternal and placental vessels
