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
Explanation
Choice A reason: A fruity odor in the breath is a symptom of hyperglycemia, especially when it is severe and causes ketoacidosis. Ketoacidosis is a condition where the body produces ketones, which are acidic substances that result from the breakdown of fat for energy when there is not enough insulin or glucose available. Ketones can make the breath smell fruity or like nail polish remover.
Choice B reason: A decreased appetite is not a symptom of hyperglycemia. On the contrary, an increased appetite or hunger is a symptom of hyperglycemia, as the body tries to compensate for the lack of glucose in the cells by stimulating the hunger center in the brain.
Choice C reason: An increased thirst is a symptom of hyperglycemia, as the body tries to flush out the excess glucose and ketones in the blood through urine. This leads to dehydration and thirst signals in the brain.
Choice D reason: A blurry vision at times is a symptom of hyperglycemia, as high blood glucose levels can cause swelling and damage to the lens of the eye, affecting its ability to focus light properly. This can lead to temporary or permanent vision problems.
Correct Answer is A
Explanation
Choice A: Maintain the client in Fowler’s position. This is correct because Fowler’s position, which is a semi-sitting position with the head of the bed elevated 45 to 60 degrees, can facilitate the drainage of gastric contents and reduce the risk of aspiration.
Choice B: Use sterile water to irrigate the nasogastric tube. This is incorrect because sterile water is not necessary to irrigate the nasogastric tube, unless the client is immunocompromised or has a high risk of infection. Tap water or normal saline can be used to irrigate the nasogastric tube, following the provider’s orders or the facility’s protocol.
Choice C: Moisten the client’s lips with lemon-glycerin swabs. This is incorrect because lemon-glycerin swabs can dry out and irritate the client’s lips and oral mucosa, especially if used frequently. The nurse should use water-soluble lubricant or lip balm to moisturize the client’s lips and mouth.
Choice D: Measure abdominal girth daily. This is incorrect because measuring abdominal girth daily is not enough to monitor the progression of the intestinal obstruction and the effectiveness of the gastrointestinal decompression. The nurse should measure abdominal girth more frequently, such as every 4 hr or every shift, and report any changes or abnormalities.
