Read the first 7 In Pregnancy flashcards as text

  1. A 28-week pregnant trauma patient presents with uterine rigidity and severe abdominal pain after a fall. The fetal heart rate is 90 bpm. What is the priority intervention?

    Answer: Immediate rapid transport to a trauma center

    Fetal bradycardia with uterine rigidity suggests placental abruption requiring immediate surgical intervention only available at a hospital.

  2. Which physiologic change of pregnancy increases the risk of aspiration during airway management?

    Answer: Reduced lower esophageal sphincter tone

    Progesterone reduces lower esophageal sphincter tone and slows gastric emptying, increasing aspiration risk in pregnant patients.

  3. What is the minimum gestational age at which fetal viability is generally considered possible in the US?

    Answer: 22–24 weeks

    Fetal viability is generally considered possible at 22–24 weeks of gestation with advanced neonatal support.

  4. When placing IV access in a critically injured pregnant patient, which site is preferred?

    Answer: Antecubital fossa or above

    IV access should be established above the diaphragm because the gravid uterus may compress the inferior vena cava, reducing flow from lower extremity IVs.

  5. Perimortem cesarean delivery (PMCD) should ideally be performed within how many minutes of maternal cardiac arrest for the best neonatal outcome?

    Answer: 5 minutes

    PMCD performed within 5 minutes of maternal arrest gives the best chance of intact neonatal survival and may also improve maternal resuscitation.

  6. A pregnant trauma patient at 30 weeks reports she felt the baby 'stop moving' after a car crash 2 hours ago. Which assessment is most important in the field?

    Answer: Fetal heart tones

    Absent or abnormal fetal heart tones after trauma indicate possible fetal compromise requiring urgent hospital evaluation.

  7. Which mechanism of injury is most commonly associated with fetal death in blunt abdominal trauma?

    Answer: Placental abruption

    Placental abruption is the most frequent cause of fetal death in blunt abdominal trauma, occurring even without apparent external injury.
