Read the first 6 Obstetric and Gynecologic Emergencies flashcards as text

  1. A 26-year-old woman presents with acute pelvic pain, vaginal bleeding, and a positive pregnancy test. She has a BP of 80/50 mmHg and signs of peritoneal irritation. What is the most likely diagnosis?

    Answer: Ruptured ectopic pregnancy

    Hemodynamic instability with pelvic pain, vaginal bleeding, and positive pregnancy test is ruptured ectopic pregnancy until proven otherwise, requiring emergent surgical intervention.

  2. A 36-week pregnant patient presents with severe headache, visual disturbances, BP of 160/110 mmHg, and 3+ proteinuria. What is the diagnosis?

    Answer: Severe preeclampsia

    BP ≥160/110 mmHg with headache, visual changes, and proteinuria after 20 weeks meets criteria for severe preeclampsia with severe features.

  3. What is the drug of choice to prevent and treat seizures in eclampsia?

    Answer: Magnesium sulfate 4–6 g loading dose IV

    Magnesium sulfate is the drug of choice for eclampsia prophylaxis and treatment, given as a 4–6 g IV loading dose over 20–30 minutes followed by a maintenance infusion.

  4. A patient at 34 weeks gestation presents with painless, bright red vaginal bleeding. What is the most likely cause?

    Answer: Placenta previa

    Painless bright red vaginal bleeding in the third trimester is the classic presentation of placenta previa, where the placenta covers the cervical os.

  5. Which assessment is CONTRAINDICATED in a patient with suspected placenta previa?

    Answer: Digital cervical examination

    Digital cervical examination is absolutely contraindicated in placenta previa as it can disrupt the placenta, causing life-threatening hemorrhage.

  6. A postpartum patient (1 hour after delivery) develops heavy vaginal bleeding with a boggy, enlarged uterus. What is the priority intervention?

    Answer: Uterine massage and oxytocin administration

    Uterine atony is the most common cause of postpartum hemorrhage; bimanual uterine massage combined with IV oxytocin is the first-line treatment to stimulate uterine contraction.
