A patient is receiving radioactive iodine treatment for hyperthyroidism. What will you include in your patient education to this patient about this type of treatment?

A. Taste changes and swollen salivary glands
B. Constipation
C. Excessive thirst
D. Sun protection

The correct answer is: A. Taste changes and swollen salivary glands

When educating a patient receiving radioactive iodine treatment for hyperthyroidism, it's crucial to inform them about potential adverse effects associated with this therapy. One significant aspect to discuss is the possibility of taste changes and swollen salivary glands. Radioactive iodine is absorbed by the thyroid gland, but it can also affect the tissues in the salivary glands. This can lead to temporary or even long-term changes in taste perception. Additionally, the treatment can cause inflammation and swelling of the salivary glands, which can produce discomfort or a feeling of fullness in the mouth. Providing this information helps the patient prepare for and manage these side effects effectively. While constipation, excessive thirst, and the need for sun protection are considerations for patients undergoing various treatments, they are not commonly highlighted as direct effects of radioactive iodine. Understanding the specific interactions and expected outcomes of radioactive iodine can empower patients to identify symptoms accurately and seek timely assistance if they encounter significant challenges.
