A nurse is providing education to a client who has Graves' disease and who will be returning home after receiving their first dose of radioactive iodine therapy. Which of the following information should the nurse include?

"You may need to repeat this therapy again in three weeks if the first dose doesn't achieve optimal results."

"Avoid being close to pregnant women and children for 7 days after your treatment."

"You may need to begin corticosteroid replacement therapy after this treatment."

"The purpose of this therapy is to increase your levels of thyroid hormone."

Answer and Explanation

The Correct Answer is B

A. "You may need to repeat this therapy again in three weeks if the first dose doesn't achieve optimal results": Radioactive iodine therapy may require additional doses, but this is not determined by a set timeframe such as three weeks. The need for additional therapy is based on the individual’s response and thyroid function tests.
B. "Avoid being close to pregnant women and children for 7 days after your treatment": This is correct as radioactive iodine therapy can emit radiation, and avoiding close contact with vulnerable populations such as pregnant women and children helps minimize their exposure to radiation.
C. "You may need to begin corticosteroid replacement therapy after this treatment": This is incorrect because corticosteroid replacement is not typically required after radioactive iodine therapy for Graves' disease. The treatment primarily targets the thyroid gland.
D. "The purpose of this therapy is to increase your levels of thyroid hormone": This is incorrect. The purpose of radioactive iodine therapy is to reduce thyroid hormone production by destroying thyroid tissue, which helps to manage hyperthyroidism in Graves' disease.

Correct Answer is B

Explanation

A. Excess mineralocorticoids: Mineralocorticoids primarily affect electrolyte and fluid balance. While excess mineralocorticoids can cause hypertension and fluid retention, they are not directly responsible for hirsutism or acne.
B. Excess adrenal androgens: Cushing syndrome can lead to elevated levels of adrenal androgens, which are responsible for hirsutism (excessive hair growth) and acne due to their androgenic effects.
C. Excess thyroid hormone: Thyroid hormone imbalances can affect various body systems, but they are not directly related to the development of hirsutism or acne seen in Cushing syndrome.
D. Excess glucocorticoids: While excess glucocorticoids are characteristic of Cushing syndrome and can cause a range of symptoms, hirsutism and acne are specifically due to excess adrenal androgens rather than glucocorticoids.

A. Weight gain and lethargy B. Nervousness and tachycardia C. Facial puffiness and constipation D. Hypotension and intolerance to cold

Correct Answer is B

Explanation

A. Weight gain and lethargy: These symptoms are more commonly associated with hypothyroidism or insufficient thyroid hormone levels, not with excess levothyroxine.
B. Nervousness and tachycardia: Excessive levothyroxine can lead to symptoms of hyperthyroidism, such as increased heart rate (tachycardia) and nervousness. These symptoms are consistent with an overdose of levothyroxine.
C. Facial puffiness and constipation: These symptoms are indicative of hypothyroidism, not hyperthyroidism. They would not be expected with an excess of levothyroxine.
D. Hypotension and intolerance to cold: These are symptoms of hypothyroidism and would not typically occur with an excess of levothyroxine. Excess levothyroxine usually causes symptoms of hyperthyroidism.
