A client is experiencing tachycardia and tremors. Lab values show elevated Free T4 and low thyroid stimulating hormone (TSH). Which diagnostic study will help the practitioner differentiate Graves' disease from other forms of hyperthyroidism?
Levothyroxine replacement test
Radioactive iodine uptake (RAIU) test
Adrenocorticotropic hormone (ACTH) stimulation test
Subtotal thyroidectomy
The Correct Answer is B
A. Levothyroxine replacement test: This test is used to assess the thyroid's response to synthetic thyroid hormone and is not used to differentiate types of hyperthyroidism.
B. Radioactive iodine uptake (RAIU) test: This test measures the thyroid gland's ability to absorb iodine, which helps differentiate Graves' disease (characterized by increased uptake) from other forms of hyperthyroidism, such as thyroiditis (which may show decreased uptake).
C. Adrenocorticotropic hormone (ACTH) stimulation test: This test is used to evaluate adrenal function and is not relevant for diagnosing or differentiating forms of hyperthyroidism.
D. Subtotal thyroidectomy: This is a surgical procedure rather than a diagnostic test and would not be used to differentiate between types of hyperthyroidism.

Correct Answer is B
Explanation
A. I will need to wear a medical alert bracelet at all times: This statement is correct. Clients with Addison's disease should wear a medical alert bracelet to inform healthcare providers of their condition in case of an emergency, as it could impact treatment decisions.
B. I will need to hold my hydrocortisone dose if I have an infection: This statement indicates a need for additional teaching. Clients with Addison's disease should not hold their hydrocortisone dose if they have an infection. In fact, they may need to increase their dose during periods of stress or illness to manage their condition effectively.
C. I will take my hydrocortisone tablets twice a day: This statement is correct. Hydrocortisone is typically taken in divided doses to mimic the natural release of cortisol from the adrenal glands.
D. I will need to eat a high-sodium diet: This statement is correct. Clients with Addison's disease often need to increase their sodium intake, as they may have difficulties retaining sodium due to adrenal insufficiency.
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.
