Thalidomide is described as ...

A stimulant medication A non-teratogenic supplement A vaccine A teratogenic medication that caused limb defects

Correct Answer:

A teratogenic medication that caused limb defects

Explanation:

Thalidomide is best described as a teratogenic medication that caused limb defects. Historically, it was given to pregnant women as a sedative and antiemetic, but it led to thousands of babies being born with serious congenital limb abnormalities, often during early stages of fetal limb development. This outcome showed that thalidomide can disrupt normal fetal growth, especially affecting limb formation, which is the hallmark of its teratogenic effects. In modern medical use, it’s kept under strict controls with pregnancy prevention protocols precisely because of that teratogenic risk, and it is not considered a stimulant, a vaccine, or a non-teratogenic supplement.
