Write answer in between .Q: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, 8050 mmHg; heart rate, 117min and irregular; respiratory rate, 20min; and temperature, 36.2C 97.1. The fetal heart rate is 103min. 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 millionsmLHb: 7.2 gdLPlatelet count: 61,000mm3Prothrombin time: 310 seconds control 20 secondsPartial prothrombin time: 420 secondsSerum fibrinogen: 16 mgdLElevated levels of which of the following laboratory markers is characteristic for this patients complication?? A: Procalcitonin, B: C-reactive protein, C: Creatinine, D: D-dimer, E: Pro-brain natriuretic peptide,  <response>: This is a question about a 34-year-old pregnant woman at 30 weeks gestation who was physically assaulted by her husband. She is now experiencing severe vaginal bleeding, abdominal pain, and other concerning vital signs and exam findings. The question asks which elevated laboratory marker is characteristic of her complication. Based on the information provided, this patient likely has placental abruption leading to disseminated intravascular coagulation DIC. Key findings supporting this include the trauma history, tetanic contractions, heavy vaginal bleeding with clots, enlarged retroplacental hematoma on ultrasound, low platelet count, prolonged PTPTT, low fibrinogen, and high D-dimer. Of the laboratory markers listed, an elevated D-dimer is most characteristic of DIC from placental abruption in this setting. The other markers may be elevated in other conditions but are not specifically indicative of DIC.D: D-dimer
