She is in her 38th week of pregnancy and her course has thus far been uncomplicated. This morning, she began feeling painful contractions and noted vaginal bleeding after she fell off her bike while riding to work. She is experiencing lower abdominal and pelvic pain between contractions as well. Her temperature is 97.6F 36.4C, blood pressure is 17799 mmHg, pulse is 100min, respirations are 20min, and oxygen saturation is 98 on room air. Physical exam is notable for a gravid and hypertonic uterus and moderate blood in the vaginal vault. Ultrasound reveals no abnormalities. Which of the following is the most likely diagnosis?? A: Abruptio placentae, B: Normal labor, C: Placenta previa, D: Uterine rupture, E: Vasa previa,  <response>: This is a question about diagnosing the cause of vaginal bleeding and abdominal pain in a pregnant woman at 38 weeks gestation. Based on the information provided, the key findings are:- 31-year-old woman at 38 weeks pregnancy- History of hypertension- Vaginal bleeding after falling off a bike - Lower abdominal and pelvic pain between contractions- Vital signs notable for elevated blood pressure - Physical exam shows gravid, hypertonic uterus and moderate vaginal bleeding- Normal ultrasoundThe main diagnostic considerations based on these findings are abruptio placentae, placenta previa, uterine rupture, and normal labor. Abruptio placentae is separation of the placenta from the uterine wall leading to vaginal bleeding. Placenta previa is a low-lying placenta covering the cervix, also causing bleeding. Uterine rupture would cause bleeding and abdominal pain. The history of trauma from falling off the bike makes abruptio placentae most likely. The other findings of contractions, hypertonic uterus, and late pregnancy support normal labor, but the bleeding makes this less likely.A: Abruptio placentae
