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 detects antithyroid antibodies in your blood.”
“This test measures the amount of thyroid hormone that ataches to a protein in your blood.”
“This test determines whether your thyroid gland is overactive, appropriately active, or underactive.”
“This test measures the absorption of iodine and how it relates to the thyroid gland.”
The Correct Answer is C
Choice A reason: This test does not detect antithyroid antibodies in your blood. Antithyroid antibodies are proteins that atack the thyroid gland and can cause autoimmune thyroid diseases, such as Hashimoto’s thyroiditis or Graves’ disease. To detect antithyroid antibodies, you need a different blood test called the thyroid peroxidase (TPO) antibody test.
Choice B reason: This test does not measure the amount of thyroid hormone that ataches to a protein in your blood. Thyroid hormone can exist in two forms in the blood: free or bound. Free thyroid hormone is not atached to any protein and can enter the cells and tissues where it is needed. Bound thyroid hormone is atached to a protein called thyroxine-binding globulin (TBG) and cannot enter the cells and tissues. To measure the amount of thyroid hormone that ataches to TBG, you need a different blood test called the total thyroxine (T4) test.
Choice C reason: This test determines whether your thyroid gland is overactive, appropriately active, or underactive. TSH is a hormone produced by the pituitary gland that stimulates the thyroid gland to make and release thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3). These hormones regulate many body functions, such as metabolism, growth, and development. The TSH test measures the amount of TSH in the blood and reflects how well the thyroid gland is working. If the TSH level is high, it means that the thyroid gland is underactive (hypothyroidism) and not making enough thyroid hormones. If the TSH level is low, it means that the thyroid gland is overactive (hyperthyroidism) and making too much thyroid hormones.
Choice D reason: This test does not measure the absorption of iodine and how it relates to the thyroid gland. Iodine is a mineral that is essential for the production of thyroid hormones. The thyroid gland absorbs iodine from the food and water we consume and uses it to make T4 and T3. To measure the absorption of iodine by the thyroid gland, you need a different test called the radioactive iodine uptake (RAIU) test.

Correct Answer is B
Explanation
Choice A: Sensitivity to cold. This is incorrect because sensitivity to cold is a manifestation of hypothyroidism, not hyperthyroidism. Clients with hyperthyroidism have increased metabolism and heat production, which makes them more sensitive to heat.
Choice B: Frequent mood changes. This is correct because frequent mood changes are a manifestation of hyperthyroidism. Clients with hyperthyroidism have increased levels of thyroid hormones, which can affect their nervous system and cause irritability, anxiety, nervousness, or emotional instability.
Choice C: Weight gain. This is incorrect because weight gain is a manifestation of hypothyroidism, not hyperthyroidism. Clients with hyperthyroidism have increased metabolism and appetite, which makes them lose weight or have difficulty gaining weight.
Choice D: Constipation. This is incorrect because constipation is a manifestation of hypothyroidism, not hyperthyroidism. Clients with hyperthyroidism have increased bowel motility and peristalsis, which makes them more prone to diarrhea or frequent stools.
Correct Answer is C
Explanation
Choice A: Ketoacidosis. This is incorrect because ketoacidosis is a complication of hyperglycemia, not hypoglycemia. Ketoacidosis occurs when the body breaks down fat for energy due to insufficient insulin, resulting in the accumulation of ketones and acids in the blood. Ketoacidosis can cause symptoms such as nausea, vomiting, abdominal pain, fruity breath odor, deep and rapid breathing, and altered mental status.
Choice B: Hyperglycemia. This is incorrect because hyperglycemia is a condition of high blood glucose, not low blood glucose. Hyperglycemia can occur due to insufficient insulin, excessive carbohydrate intake, infection, stress, or illness. Hyperglycemia can cause symptoms such as polyuria, polydipsia, polyphagia, blurred vision, fatigue, and headache.
Choice C: Hypoglycemia. This is correct because hypoglycemia is a condition of low blood glucose, which can occur due to excessive insulin, inadequate carbohydrate intake, exercise, alcohol consumption, or medication interactions. Hypoglycemia can cause symptoms such as sweating, tachycardia, palpitations, tremors, hunger, anxiety, confusion, dizziness, weakness, and seizures.
Choice D: Nephropathy. This is incorrect because nephropathy is a complication of chronic hyperglycemia, not acute hypoglycemia. Nephropathy is a kidney disease that results from damage to the small blood vessels and glomeruli in the kidneys due to high blood glucose levels. Nephropathy can cause symptoms such as proteinuria, edema, hypertension, and renal failure.
