The most common serious complication of multiple gestation pregnancy is:
Answer: Preterm birth before 37 weeks
Preterm birth is the most frequent and clinically significant complication of twin and higher-order multiple pregnancies, occurring in the majority of cases.
Monochorionic-diamniotic (MCDA) twins share a placenta and are at specific risk for which serious complication not seen in dichorionic twins?
Answer: Twin-to-twin transfusion syndrome (TTTS)
TTTS occurs in 10–15% of MCDA twins due to unequal sharing of blood flow through placental vascular anastomoses, causing one twin to become donor and the other recipient.
Weekly 17-alpha hydroxyprogesterone caproate (17-OHPC) injections are indicated to reduce preterm birth risk in which patient population?
Answer: Women with a singleton pregnancy and a prior spontaneous preterm birth
17-OHPC is FDA-indicated for singleton pregnancies in women with a documented prior spontaneous preterm birth to reduce recurrence risk.
A cervical length of less than what measurement on transvaginal ultrasound is the standard threshold associated with significantly increased preterm birth risk?
Answer: 2.5 cm
A cervical length of less than 2.5 cm (25 mm) on transvaginal ultrasound between 16–24 weeks is the established threshold for increased spontaneous preterm birth risk.
Which tocolytic agent is contraindicated in patients with cardiac disease due to its cardiovascular side effects?
Answer: Terbutaline and other beta-agonists
Beta-agonist tocolytics (terbutaline, ritodrine) cause tachycardia, hypotension, and increased myocardial oxygen demand, making them contraindicated in patients with cardiac disease.
Antenatal corticosteroids (betamethasone) to accelerate fetal lung maturity are indicated between which gestational ages?
Answer: 24–34 weeks
ACOG recommends a single course of betamethasone at 24 0/7 to 33 6/7 weeks for women at risk of preterm delivery within 7 days to reduce respiratory distress syndrome.
