A 34-year-old G3P2 is admitted to the hospital after being physically assaulted by her husband. She developed severe vaginal bleeding and abdominal pain. She is at 30 weeks gestation. Her previous pregnancies were uncomplicated, as has been the course of the current pregnancy. The vital signs are as follows: blood pressure, 80/50 mmHg; heart rate, 117/min and irregular; respiratory rate, 20/min; and temperature, 36.2℃ (97.1). The fetal heart rate is 103/min. On physical examination, the patient is pale and lethargic. Abdominal palpation reveals severe uterine tenderness and tetanic contractions. The perineum is grossly bloody. There are no vaginal or cervical lesions. There is active heavy bleeding with blood clots passing through the cervix. An ultrasound shows a retroplacental hematoma with a volume of approximately 400 ml. Laboratory workup shows the following findings: Red blood cells count: 3.0 millions/mL Hb%: 7.2 g/dL Platelet count: 61,000/mm3 Prothrombin time: 310 seconds (control 20 seconds) Partial prothrombin time: 420 seconds Serum fibrinogen: 16 mg/dL Elevated levels of which of the following laboratory markers is characteristic for this patient’s complication?

Four months after giving birth, a young woman presents to the hospital complaining of lack of breast milk secretion. The patient complains of constantly feeling tired. Physical exam reveals that she is slightly hypotensive and has lost a significant amount of weight since giving birth. The patient states that she has not experienced menstruation since the birth. Which of the following is likely to have contributed to this patient's presentation?

A 30-year-old woman, gravida 2, para 1, at 42 weeks' gestation is admitted to the hospital in active labor. Pregnancy has been complicated by gestational diabetes, for which she has been receiving insulin injections. Her first child was delivered by lower segment transverse cesarean section because of a nonreassuring fetal heart rate. Her pulse is 90/min, respirations are 18/min, and blood pressure is 135/80 mm Hg. The fetal heart rate tracing shows a baseline heart rate of 145/min and moderate variation with frequent accelerations and occasional early decelerations. She undergoes an elective repeat lower segment transverse cesarean section with complete removal of the placenta. Shortly after the operation, she starts having heavy uterine bleeding with passage of clots. Examination shows a soft uterus on palpation. Her bleeding continues despite fundal massage and the use of packing, oxytocin, misoprostol, and carboprost. Her pulse rate is now 120/min, respirations are 20/min, and blood pressure is 90/70 mm Hg. Her hemoglobin is 8 g/dL, hematocrit is 24%, platelet count is 120,000 mm3, prothrombin time is 11 seconds, and partial thromboplastin time is 30 seconds. Mass transfusion protocol is activated and a B-Lynch uterine compression suture is placed to control her bleeding. Which of the following is the mostly likely cause of her postpartum complication?

Two days after being admitted to the hospital because of severe peripartum vaginal bleeding during a home birth, a 40-year-old woman, gravida 3, para 3, has a 30-second generalized convulsive seizure followed by unconsciousness. Prior to the event she complained of acute onset of sweating and uncontrollable shivering. She was hemodynamically unstable and required several liters of intravenous fluids and 5 units of packed red blood cells in the intensive care unit. The patient's two prior pregnancies, at ages 33 and 35, were uncomplicated. She is otherwise healthy. Prior to admission, her only medication was a daily prenatal vitamin. Temperature is 37.5°C (99.5°F), pulse is 120/min, respirations are 18/min, blood pressure is 101/61 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 96%. Examination shows very little milk expression from the breasts bilaterally. Finger-stick glucose level is 36 mg/dL. Which of the following is the most likely underlying cause of this patient's condition?

29-year-old G2P2002 presents with foul-smelling lochia and fever. She is post-partum day three status-post cesarean section due to eclampsia. Her temperature is 101 F, and heart rate is 103. She denies chills. On physical exam, lower abdominal and uterine tenderness is present. Leukocytosis with left shift is seen in labs. Which of the following is the next best step in management?

A 36-year-old woman, gravida 3, para 3, presents to the postpartum clinic complaining of left breast pain. She gave birth 3 weeks ago, and the breast pain started yesterday. She has exclusively breastfed her infant since birth. She says she hasn't been feeling well for the past 2 days and has experienced fatigue and muscle soreness. Her temperature is 38.3°C (101°F). Physical examination shows the lateral side of her left breast to be erythematous and warm. Which of the following is the most appropriate next step in management?

Three days after delivering a baby at 36 weeks' gestation by lower segment transverse cesarean section due to abruptio placentae, a 29-year-old primigravid woman develops fever, chills, and a heavy feeling in her breasts. She also has nausea and abdominal pain. Her temperature is 39.3°C (102.7°F), pulse is 101/min, and blood pressure is 110/70 mm Hg. Examination shows full and tender breasts and mild lower limb swelling. Abdominal examination shows diffuse tenderness with no guarding or rebound. Pelvic examination shows foul-smelling lochia and marked uterine tenderness. Laboratory studies show: Hemoglobin 11.3 g/dL Leukocyte count 16,300/mm3 D-dimer 130 ng/mL(N < 250 ng/mL) Serum Creatinine 1.2 mg/dL Pelvic ultrasonography shows an empty uterus. Which of the following is the most appropriate next step in management?

A 26-year-old woman presents to her physician with a complaint of milk reduction. 2 months ago, she delivered a healthy girl from an uncomplicated pregnancy. The baby was exclusively breastfed until 1.5 months when the patient had to return to the workforce. She cannot breastfeed her daughter at work so she had to leave her with her grandmother and incorporated baby formula into her diet. She reports breast engorgement shortly after she switched to the described regimen which subsided soon. A week after she switched to such a regimen, she started to notice that she has less milk to feed her baby when she is at home.
