Q

Jane lives in Appalachia and suffers from hypothyroidism ( low T3 and T4). Her thyroid gland is enlarged, her body temperature is low, and her heart rate is very low. Blood test shows very little iodine in blood and very low T3 and T4.

Choose correct statement that explains why her thyroid gland was enlarged.

Q

Jane lives in Appalachia and suffers from hypothyroidism ( low T3 and T4). Her thyroid gland is enlarged, her body temperature is low, and her heart rate is very low. Blood test shows very little iodine in blood and very low T3 and T4.

What would be her TSH level and why?

A

Her TSH would be high because lack of iodine leads to decrease of T3 and T4 in plasma
