The nurse in the emergency room is reviewing the health record of a client who is being evaluated for Graves' disease. The nurse should identify which of the following laboratory results is an expected finding?
Decreased thyrotropin receptor antibodies
Decreased free thyroxine index
Decreased triiodothyronine
Decreased thyroid-stimulating hormone (TSH)
The Correct Answer is D
A. Decreased thyrotropin receptor antibodies: Graves' disease is characterized by the presence of thyrotropin receptor antibodies, so they are typically increased, not decreased.
B. Decreased free thyroxine index: Graves' disease typically results in increased levels of thyroid hormones, not decreased.
C. Decreased triiodothyronine: T3 levels may be elevated in Graves' disease due to increased thyroid hormone production.
D. Decreased thyroid-stimulating hormone (TSH): Graves' disease causes excessive thyroid hormone production, leading to suppressed TSH levels. TSH is typically low in hyperthyroidism because the thyroid gland is overactive and not being stimulated by the pituitary gland.

C. Having multiple siblings: Having multiple children does not directly increase the risk of shaking unless coupled with other stressors.
