If a patient's thyroid gland is exposed to radioactive iodine, which consequence follows regarding thyroid hormone production?

💡 Explanation

Radioactive iodine is absorbed by the thyroid, destroying thyroid follicular cells; because of this damage, less thyroxine (T4) and triiodothyronine (T3) are synthesized. Therefore thyroid hormone production decreases, rather than increasing hormone production through altered receptor sensitivity or conversion rates.
