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."
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 A
Explanation
A. B-type natriuretic peptide (BNP): BNP levels are elevated in heart failure due to the heart's response to increased pressure and volume overload. This biomarker is used specifically to diagnose and assess the severity of heart failure.
B. Troponin I: This is a marker for myocardial injury and is used to diagnose acute myocardial infarction rather than heart failure.
C. Blood urea nitrogen (BUN): While elevated BUN can be associated with renal dysfunction or fluid overload in heart failure, it is not specific to diagnosing heart failure.
D. Platelet levels: These are not directly related to diagnosing heart failure and do not provide information about cardiac function.
Correct Answer is D
Explanation
A. Radioactive iodine therapy: This is contraindicated during pregnancy as it can harm the fetus and affect thyroid function.
B. Levothyroxine: This is used for hypothyroidism, not hyperthyroidism. For hyperthyroidism, this medication would not be appropriate.
C. Ketoconazole: This is an antifungal and is not used to treat hyperthyroidism.
D. Propylthiouracil (PTU): PTU is the preferred treatment during the first trimester of pregnancy for hyperthyroidism. It inhibits thyroid hormone synthesis and is considered safer than methimazole during early pregnancy.
