The nurse is educating a newly diagnosed client about treatment for hyperthyroidism. Which of the following statements would require further teaching?
It is important that I take my levothyroxine daily to help manage my hyperthyroidism
I should avoid foods like kale, cabbage, Brussel sprouts, and cauliflower
Methimazole will decrease my T3 and T4 levels
Iodine will prevent the thyroid hormone from being released into the bloodstream
The Correct Answer is A
Choice A reason: Levothyroxine treats hypothyroidism by adding T4, worsening hyperthyroidism’s excess hormone; antithyroid drugs are needed, so this statement is incorrect.
Choice B reason: Avoiding goitrogens (kale, cabbage) prevents thyroid suppression, appropriate in hyperthyroidism where reducing hormone production is the goal, so this is correct.
Choice C reason: Methimazole inhibits thyroid hormone synthesis, lowering T3 and T4 in hyperthyroidism, a standard treatment, making this statement accurate.
Choice D reason: Iodine blocks thyroid hormone release, reducing circulating T3/T4 in hyperthyroidism, a correct approach, especially in acute settings, so this is valid.

Correct Answer is B
Explanation
Choice A reason: Fever of 103°F may occur in thyroid storm, not goiter, which is simply thyroid enlargement without systemic hypermetabolism or infection necessarily.
Choice B reason: Goiter is defined by thyroid gland enlargement, often from iodine deficiency or hyperplasia, palpable as a neck mass, the core characteristic here.
Choice C reason: Fibrotic tissue in arterioles relates to vascular diseases, not goiter, which involves thyroid tissue growth, not arterial structural changes.
Choice D reason: Glycosaminoglycan deposits occur in myxedema (hypothyroidism), not goiter, which is enlargement alone, not skin or connective tissue alteration.
Correct Answer is A
Explanation
Choice A reason: Hypothyroidism slows metabolism due to low thyroid hormone, reducing calorie burning and causing weight gain from fat accumulation and fluid retention in tissues.
Choice B reason: Diaphoresis (sweating) occurs in hyperthyroidism from excess metabolism raising body heat. Hypothyroidism causes dry skin and cold intolerance, not sweating.
Choice C reason: Exophthalmos, bulging eyes, results from Graves’ disease in hyperthyroidism due to orbital inflammation. Hypothyroidism doesn’t affect eye protrusion, making this unlikely.
Choice D reason: Palpitations stem from hyperthyroidism’s increased heart rate via excess thyroid hormone. Hypothyroidism slows heart rate, leading to bradycardia, not palpitations.
