An older patient has been diagnosed with hyperthyroidism. Which treatment will the nurse anticipate?

1. Partial thyroidectomy
2. Ingestion of radioactive sodium iodine
3. Combination treatment with Synthroid and amiodarone
4. Large doses of propylthiouracil (PTU) and intravenous propranolol


2. Ingestion of radioactive sodium iodine


Explanation: 1. Surgical removal is reserved for patients with symptoms too severe for treatment with radioactive iodine or nodules suspicious for malignancy.
2. The treatment of choice is ingestion of the radioactive iodine, which is picked up by the thyroid tissue and then destroys the tissue. This treatment avoids surgery, anesthesia, and hospitalization.
3. Treatment with Synthroid would worsen symptoms, and amiodarone is an antiarrhythmic drug that has induced hyperthyroidism in some patients.
4. Large doses of propylthiouracil (PTU) and intravenous propranolol are used to treat thyroid storm and not hyperthyroidism.
