. A nurse is reinforcing teaching with a client who is scheduled for a blood test to measure her thyroid-stimulating hormone (TSH) level. Which of the following statements should the nurse give?
"This test measures the absorption of iodine and how it relates to the thyroid gland."
"The test determines whether your thyroid gland is overactive, appropriately active, or underactive."
"This test detects antithyroid antibodies in your blood."
"This test measures the amount of thyroid hormone that attaches to a protein in your blood."
The Correct Answer is B
A. "This test measures the absorption of iodine and how it relates to the thyroid gland.": This describes a radioactive iodine uptake (RAIU) test, not TSH testing.
B. "The test determines whether your thyroid gland is overactive, appropriately active, or underactive.": A TSH test evaluates thyroid function by measuring the pituitary gland’s response to circulating thyroid hormone levels.
C. "This test detects antithyroid antibodies in your blood.": This describes a thyroid antibody test, which is used to diagnose autoimmune thyroid conditions like Hashimoto’s thyroiditis or Graves’ disease.
D. "This test measures the amount of thyroid hormone that attaches to a protein in your blood.": This describes a thyroid hormone-binding ratio test, not TSH.

Correct Answer is B
Explanation
A. Hypernatremia: Addison’s disease causes low aldosterone levels, leading to hyponatremia rather than hypernatremia.
B. Hypotension: Addison's disease causes insufficient cortisol and aldosterone, resulting in fluid loss and low blood pressure, especially in stress or postoperative states.
C. Bradycardia: Addison’s disease does not typically affect heart rate directly, though hypotension may cause a compensatory increase in heart rate (tachycardia).
D. Hypokalemia: Addison's disease leads to hyperkalemia due to low aldosterone levels, which reduce potassium excretion by the kidneys.
