Practice Question
A nurse in the labor and delivery unit is reviewing medications for a group of clients. Which of the following medications places the fetus at risk for teratogenic effects?
Answer Choices:
Correct Answer:
Phenytoin for seizure disorder
Rationale:
⚠️ Phenytoin is an anticonvulsant that is known to be teratogenic, meaning it can cause developmental abnormalities in the fetus if taken during pregnancy.
⚠️ Fetal hydantoin syndrome—characterized by growth deficiencies, craniofacial anomalies, and limb defects—is a documented risk with phenytoin exposure.
⚠️ While seizure control is important during pregnancy, alternative or safer anticonvulsants may be considered, and close monitoring is essential.
⚠️ Levothyroxine, magnesium oxide, and ferrous sulfate are generally considered safe during pregnancy and are often necessary for maternal health.
⚠️ Teratogenic risk is highest during the first trimester when organogenesis occurs.
