Air travel in pregnancy is not recommended after What gestational age
**Core Concept**
Air travel during pregnancy is a topic of concern due to the risk of hypoxia, decompression sickness, and preterm labor. The American College of Obstetricians and Gynecologists (ACOG) and other reputable sources have guidelines for safe air travel during pregnancy.
**Why the Correct Answer is Right**
Air travel is generally safe after the first trimester, but there is a specific gestational age limit for non-urgent air travel. This is because air pressure changes during flight can cause fetal distress, and there is a risk of preterm labor. The American College of Obstetricians and Gynecologists recommends avoiding air travel after 36 weeks of gestation due to the increased risk of preterm labor. The risk of preterm labor is higher after 36 weeks because the cervix is more likely to dilate and efface, which can lead to premature birth.
**Why Each Wrong Option is Incorrect**
**Option A:** 28 weeks - This is too early, as air travel is generally safe after the first trimester (13-14 weeks).
**Option B:** 32 weeks - This is still early, as the risk of preterm labor is relatively low until 36 weeks.
**Option C:** 40 weeks - This is too late, as the cervix is fully dilated and effaced at term, and air travel is not recommended after 36 weeks.
**Clinical Pearl / High-Yield Fact**
Remember that air travel is generally safe after the first trimester, but it's essential to discuss individual circumstances with a healthcare provider, especially if there are any underlying medical conditions or concerns.
**Correct Answer:** C. 36 weeks
