Question

Which of the following would be higher than normal in a person who has a goiter caused by inadequate dietary intake of iodide?

A. blood level of TSH
B. blood levels of T3 and T4
C. basal metabolic rate
D. growth of bones
E. lipolysis

Answer 1

The blood level of TSH would be higher than normal in a person who has a goiter caused by inadequate dietary intake of iodide.

Step-by-step explanation:

In a person who has a goiter caused by inadequate dietary intake of iodide, the blood level of TSH (thyroid-stimulating hormone) would be higher than normal.

When there is inadequate dietary intake of iodide, the thyroid gland cannot produce enough T3 (triiodothyronine) and T4 (thyroxine) hormones. As a result, the pituitary gland produces more TSH to try to stimulate the thyroid gland to produce more thyroid hormones. This increased production of TSH leads to a higher than normal blood level of TSH.

The other options mentioned in the question, such as blood levels of T3 and T4, basal metabolic rate, growth of bones, and lipolysis, would be lower than normal in a person with inadequate dietary intake of iodide.
