Question 1 of 5
The nurse in the emergency room is reviewing the health record of a client who is being evaluated for Graves' disease. Which of the following laboratory results is an expected finding?
Correct Answer: D
Rationale: The correct answer is D: Decreased thyroid-stimulating hormone (TSH). In Graves' disease, there is excessive production of thyroid hormones, leading to negative feedback on the pituitary gland, resulting in decreased TSH levels. This is because the elevated thyroid hormone levels signal the pituitary gland to decrease TSH production.
A: Decreased thyrotropin receptor antibodies - This is incorrect as Graves' disease is associated with increased levels of these antibodies.
B: Decreased free thyroxine index - This is incorrect as Graves' disease typically presents with elevated levels of free thyroxine.
C: Decreased triiodothyronine - This is incorrect as Graves' disease is characterized by elevated levels of triiodothyronine due to increased thyroid hormone production.
In summary, the expected finding in Graves' disease is a decreased TSH level due to the negative feedback mechanism, making option D the correct choice.
