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 ["A","B","C"]
Explanation
Choice A reason: Tachycardia is a common symptom of hypoglycemia, as the body releases adrenaline and other hormones to raise the blood sugar level. This can cause the heart to beat faster and stronger.
Choice B reason: Blurry vision is a common symptom of hypoglycemia, as low blood sugar can affect the ability of the eyes to focus and see clearly. This can also cause headaches, dizziness, or double vision.
Choice C reason: Sweating is a common symptom of hypoglycemia, as the body tries to cool down and cope with the stress of low blood sugar. This can also cause shakiness, trembling, or tingling in the lips, tongue, or cheek.
Choice D reason: Polydipsia (excessive thirst) is not a symptom of hypoglycemia, but a symptom of hyperglycemia (high blood sugar). High blood sugar can cause dehydration and dry mouth, which make the person feel thirsty.
Choice E reason: Polyuria (excessive urination) is not a symptom of hypoglycemia, but a symptom of hyperglycemia (high blood sugar). High blood sugar can cause the kidneys to filter out excess glucose and water from the blood, which make the person urinate more often.
Correct Answer is D
Explanation
Choice A: Place the client on his back. This is incorrect because the client should be placed in a sitting position with the head of the bed elevated to 30 to 45 degrees. This allows the fluid to accumulate in the lower abdomen and reduces the risk of puncturing the diaphragm.
Choice B: Have the client increase fluid intake after the procedure. This is also incorrect because the client should restrict fluid intake after the procedure to prevent fluid overload and electrolyte imbalance. The nurse should monitor the client’s intake and output, weight, and vital signs.
Choice C: Assure the client that the procedure is painless. This is not true because the client may experience some discomfort or pressure during the insertion of the needle or catheter. The nurse should administer analgesics as prescribed and provide emotional support.
Choice D: Instruct the client to empty his bladder. This is correct because this reduces the risk of bladder injury during the procedure. The nurse should also measure and record the amount of urine voided.
