**Question:** Post-term pregnancy is associated with

A. Increased risk of stillbirth
B. Lower risk of congenital anomalies
C. Increased risk of preterm delivery
D. Lower risk of maternal complications

**Core Concept:** Post-term pregnancy is defined as pregnancy lasting beyond the 42nd week of gestation. The human pregnancy is typically considered to last for 40 weeks from the first day of the last menstrual period (LMP).

**Why the Correct Answer is Right:** Post-term pregnancy increases the risk of adverse maternal and neonatal outcomes due to the prolonged exposure of the fetus to the uterine environment and the mother's body to the elevated levels of maternal hormones.

A. Increased risk of stillbirth: The prolonged gestation period can lead to fetal growth restriction, hypoxia, and other complications that increase the risk of stillbirth.

B. Lower risk of congenital anomalies: This is a misconception often found in general knowledge. In reality, the risk of congenital anomalies increases with post-term pregnancy due to prolonged exposure to maternal hormones and the risk of maternal infections.

C. Increased risk of preterm delivery: While post-term pregnancy increases the risk of preterm labor and delivery, the main concern remains the increased risk of stillbirth and congenital anomalies.

D. Lower risk of maternal complications: Post-term pregnancy can lead to maternal complications such as preeclampsia, gestational diabetes, and increased risk of cesarean delivery due to fetal presentation changes or macrosomia.

**Why Each Wrong Option is Incorrect:**

A. Stillbirth risk: While the risk of stillbirth increases with post-term pregnancy, option B states that there is a lower risk of congenital anomalies. This is incorrect because congenital anomalies are actually more common in post-term pregnancies due to the prolonged exposure to maternal hormones and the risk of maternal infections.

B. Lower risk of congenital anomalies: As mentioned earlier, this is a misconception. Congenital anomalies are more common in post-term pregnancy due to prolonged exposure to maternal hormones and the risk of maternal infections.

C. Increased risk of preterm labor: While post-term pregnancy increases the risk of preterm labor and delivery, the main concern remains the increased risk of stillbirth and congenital anomalies, which outweigh the risk of preterm delivery.

D. Lower risk of maternal complications: Post-term pregnancy can lead to maternal complications such as preeclampsia, gestational diabetes, and increased risk of cesarean delivery due to fetal presentation changes or macrosomia. This option is more accurate than options A and B, but still does not address the increased risks of stillbirth and congenital anomalies associated with post-term pregnancy.

**Clinical Pearls:**

1. ACOG (American College of Obstetricians and Gynecologists) recommends inducing labor at 41 weeks for routine terminations to reduce the risk of stillbirth, congenital anomalies, and adverse maternal outcomes.
2. Clinical decision making should be individualized for each patient, considering the mother
