Final answer:
Iodide preparations are used in the short-term treatment of hyperthyroidism to suppress thyroid hormone production, but are not useful for long-term management. Over-the-counter potassium iodide tablets are not typically used to treat hyperthyroidism, and the effects of iodide suppression are not permanent.
Step-by-step explanation:
When addressing the question of which of the following is true of using iodide preparations to treat hyperthyroidism, it is important to understand the background of hyperthyroidism treatment. Hyperthyroidism is a condition where the thyroid gland is overactive, producing excessive thyroid hormones. One of the treatment options includes the use of iodide preparations. These are typically used to suppress thyroid hormone production in the short term; however, there are several points to consider:
- The iodide preparations used for iodide suppression are not taken parenterally; they are usually taken orally.
- Over-the-counter potassium iodide tablets are not the most commonly used iodide drug preparations to treat hyperthyroidism. Prescription medications or radioactive iodine are typically employed.
- Iodide suppression is not useful for the long-term treatment of hyperthyroidism. It is generally a short-term solution prior to other treatments like radioactive iodine therapy or surgery.
- The effects of iodide suppression are not permanent. The thyroid may eventually escape from the suppressive effects of iodide, resuming its overactivity.
Therefore, the correct answer from the multiple-choice options provided is that iodide suppression is not useful for the long-term treatment of hyperthyroidism.
