The intensity and frequency of pain have increased in the past 2 hours. This is her 1st pregnancy and she was diagnosed with gestational diabetes several weeks ago. Her vital signs include a blood pressure of 12468 mm Hg, a pulse of 77min, a respiratory rate of 22min, and a temperature of 37.0C 98.6F. The abdominal examination is positive for a firm and tender uterus. An immediate cardiotocographic evaluation reveals a fetal heart rate of 150min with prolonged and repetitive decelerations and high-frequency and low-amplitude uterine contractions. Your attending physician warns you about delaying the vaginal physical examination until a quick sonographic evaluation is completed. Which of the following is the most likely diagnosis in this patient?? A: Miscarriage, B: Vasa previa, C: Uterine rupture, D: Placenta previa, E: Placenta abruption,  <response>: This is a patient presenting with vaginal bleeding and uterine contractions in the third trimester. The key findings are:- 30 weeks gestation - Sudden onset vaginal bleeding - Abdominopelvic pain and uterine contractions that are increasing in intensity and frequency- First pregnancy- Diagnosed with gestational diabetes - Vital signs are normal- Firm and tender uterus on abdominal exam- Fetal heart rate showing decelerations - High-frequency, low-amplitude uterine contractionsThe most likely diagnoses to consider are:A Miscarriage - Unlikely at 30 weeks gestationB Vasa previa - No risk factors notedC Uterine rupture - Possible but less common than other diagnoses D Placenta previa - Can cause painless bleeding but not contractionsE Placenta abruption - Most likely given bleeding with painful contractionsE: Placenta abruption
