A nurse is teaching a class to a group of pregnant patients. The nurse correctly teaches that the highest risk of teratogen-induced gross malformations exists during which time?

a. Immediately before conception
b. During the first trimester
c. During the second trimester
d. During the third trimester


ANS: B
Gross malformations are caused by exposure to teratogens during the embryonic period, which is considered the first trimester. This is the time when the basic shape of internal organs and other structures is established. No risk exists immediately before conception unless the medication is a category X drug. Teratogen exposure during the second and third trimesters usually disrupts function rather than gross anatomy.
