A pregnant patient with hypothyroidism asks about treatment; which point should the nurse emphasize?

• A. Neuropsychologic deficits in the fetus can occur if the condition is not treated.
• B. Hypothyroidism is a normal effect of pregnancy.
• C. The condition only affects the mother.
• D. Treatment can wait until after delivery.

Answer: (A)

During pregnancy, maternal thyroid hormone is essential for fetal brain development, especially in the first trimester before the fetal thyroid is fully functional. If hypothyroidism is not treated, the fetus can develop neuropsychologic deficits, including cognitive impairment and developmental delays. Therefore, the most important message to emphasize is that treatment during pregnancy is necessary to protect the baby’s neurodevelopment, with thyroid hormone replacement continued and adjusted to keep thyroid function in the appropriate ranges. Hypothyroidism is not a normal effect of pregnancy, it affects both mother and fetus, and treatment should not be delayed until after delivery.
