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: Prednisolone reduces inflammation and thyroid hormone production in thyroid storm, stabilizing metabolism, a standard adjunct, so this order is appropriate.
Choice B reason: Aspirin displaces thyroid hormone from proteins, worsening hyperthyroidism in thyroid storm, risking increased T3/T4 effects, so it’s contraindicated and questionable.
Choice C reason: Diazepam controls agitation and seizures in thyroid storm’s hypermetabolic state, calming the nervous system, making it a suitable order here.
Choice D reason: Metoprolol blocks beta-adrenergic effects, slowing heart rate in thyroid storm’s tachycardia, a critical intervention, so this order is clinically sound.
Correct Answer is A
Explanation
Choice A reason: Myxedema, severe hypothyroidism, slows metabolism, reducing cardiac output and causing fluid retention in tissues, leading to non-pitting leg edema from glycosaminoglycan deposits and poor circulation.
Choice B reason: Heat intolerance occurs in hyperthyroidism due to increased metabolism raising body temperature. Myxedema causes cold intolerance from slowed metabolism, making this finding unlikely.
Choice C reason: Tachycardia is a hyperthyroid symptom from excess thyroid hormone speeding heart rate. Myxedema leads to bradycardia as metabolism and cardiac activity decrease significantly.
Choice D reason: Diarrhea aligns with hyperthyroidism’s accelerated gut motility. Myxedema causes constipation from slowed metabolism reducing peristalsis, so diarrhea contradicts this condition’s physiology.
