The use of radioactive iodine is contraindicated in which client?

Explanation:
Radioactive iodine therapy delivers radiation specifically to thyroid tissue, but that radiation can also reach a developing fetus. If the patient is pregnant, the radioactive iodine crosses the placenta and can ablate the fetal thyroid, risking severe hypothyroidism and developmental issues. Because of these fetal risks, radioactive iodine is contraindicated during pregnancy. The other scenarios don’t pose the same fetus-related risk, though lactation requires special consideration after treatment, pregnancy remains the primary contraindication.
