The nurse is educating a group of clients about the different causes of goiter. Which cause of goiter is related to a deficiency of dietary iodine?
Autoimmune thyroid disease
Excessive thyroid hormone production
Radiation exposure
Iodine deficiency
The Correct Answer is D
Iodine deficiency is a common cause of goiter, especially in regions where there is insufficient dietary intake of iodine, leading to inadequate production of thyroid hormones.
Incorrect choices:
a. Autoimmune thyroid disease, such as Hashimoto's thyroiditis, is not specifically related to iodine deficiency and is characterized by immune system attack on the thyroid gland.
b. Excessive thyroid hormone production is associated with conditions such as toxic goiter or Graves' disease and is not directly related to iodine deficiency.
c. Radiation exposure can damage the thyroid gland and lead to goiter, but it is not directly related to iodine deficiency.
