What is the anticoagulant of choice for pregnancy?

1. Warfarin

2. Heparin

3. Aspirin

4. Dipyridamole

The correct answer is: Heparin

Heparin is the preferred anticoagulant for pregnancy because it does not cross the placenta and does not cause harm to the developing fetus. Warfarin, on the other hand, can cause birth defects and should be avoided during pregnancy. Aspirin and Dipyridamole are also not recommended as anticoagulants for pregnancy as they are not as effective as Heparin and may have potential risks for the fetus. While all anticoagulants carry some level of risk, Heparin is the safest option for pregnant women.
