Postpartum hemorrhage protocols — MCQs

A 38-year-old woman, gravida 2, para 1, at 35 weeks' gestation comes to the emergency department because of an episode of vaginal bleeding that morning. The bleeding has subsided. She has had no prenatal care. Her previous child was delivered with a caesarean section because of a breech presentation. Her temperature is 37.1°C (98.8°F), pulse is 88/min, respirations are 14/min, and blood pressure is 125/85 mm Hg. The abdomen is nontender and the size of the uterus is consistent with a 35-week gestation. No contractions are felt. The fetal heart rate is 145/min. Her hemoglobin concentration is 12 g/dL, leukocyte count is 13,000/mm3, and platelet count is 350,000/mm3. Transvaginal ultrasound shows that the placenta covers the internal os. Which of the following is the most appropriate next step in management?

A 35-year-old patient is brought into the emergency department post motor vehicle crash. Stabilization of the patient in the trauma bay requires endotracheal intubation. The patient has a laceration on the femoral artery from shrapnel and seems to have lost large quantities of blood. The patient is transfused with 13 units of packed red blood cells. His vitals are T 96.5, HR 150, BP 90/40. Even with the direct pressure on the femoral artery, the patient continues to bleed. Results of labs drawn within the last hour are pending. Which of the following is most likely to stop the bleeding in this patient?

A 34-year-old primigravida was brought to an obstetric clinic with a chief complaint of painless vaginal bleeding. She was diagnosed with placenta praevia and transfused with 2 units of whole blood. Five hours after the transfusion, she developed a fever and chills. How could the current situation be prevented?

A 34-year-old G5P5 woman gave birth to a healthy infant 30 minutes ago by vacuum-assisted vaginal delivery and is now experiencing vaginal bleeding. The placenta was delivered spontaneously and was intact upon examination. The infant weighed 5.2 kg and had Apgar scores of 8 and 9. No perineal tear or intentional episiotomy occurred. The patient has type 1 diabetes. She had good glycemic control throughout her pregnancy. She took a prenatal vitamin daily. Blood pressure is 135/72 mmHg, pulse is 102/min, and respirations are 18/min. Upon physical examination, the uterine fundus is soft and palpated 4 cm above the umbilicus. There are 3-cm blood clots on the patient’s bed pad. Which of the following is the next best step in management for the patient’s bleeding?

Five minutes after initiating a change of position and oxygen inhalation, the oxytocin infusion is discontinued. A repeat CTG that is done 10 minutes later shows recurrent variable decelerations and a total of 3 uterine contractions in 10 minutes. Which of the following is the most appropriate next step in management?

Thirty minutes after normal vaginal delivery of twins, a 35-year-old woman, gravida 5, para 4, has heavy vaginal bleeding with clots. Physical examination shows a soft, enlarged, and boggy uterus. Despite bimanual uterine massage, administration of uterotonic drugs, and placement of an intrauterine balloon for tamponade, the bleeding continues. A hysterectomy is performed. Vessels running through which of the following structures must be ligated during the surgery to achieve hemostasis?

A 31-year-old G6P6 woman with a history of fibroids gives birth to twins via vaginal delivery. Her pregnancy was uneventful, and she reported having good prenatal care. Both placentas are delivered immediately after the birth. The patient continues to bleed significantly over the next 20 minutes. Her temperature is 97.0°F (36.1°C), blood pressure is 124/84 mmHg, pulse is 95/min, respirations are 16/min, and oxygen saturation is 98% on room air. Continued vaginal bleeding is noted. Which of the following is the most appropriate initial step in management?

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?

A 30-year-old woman, gravida 2, para 1, abortus 1, comes to the physician because of failure to conceive for 12 months. She is sexually active with her husband 2–3 times per week. Her first child was born at term after vaginal delivery 2 years ago. At that time, the postpartum course was complicated by hemorrhage from retained placental products, and the patient underwent dilation and curettage. Menses occur at regular 28-day intervals and previously lasted for 5 days with normal flow, but now last for 2 days with significantly reduced flow. She stopped taking oral contraceptives 1 year after the birth of her son. Her vital signs are within normal limits. Speculum examination shows a normal vagina and cervix. The uterus is normal in size, and no adnexal masses are palpated. Which of the following is the most appropriate next step in management?

Two days after vaginal delivery of a healthy newborn at term, a 32-year-old woman, gravida 2, para 2, is unable to breastfeed. Her labor was complicated by antepartum hemorrhage and she received two units of packed red blood cells. Her pulse is 99/min and blood pressure is 90/55 mm Hg. Further evaluation of this patient is most likely to show which of the following sets of serum findings? $$$ ACTH %%% Aldosterone %%% Cortisol $$$
