A nurse is reinforcing teaching about exercise with a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

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.

Choice A: Both illnesses result in malabsorption of nutrients. This is incorrect because malabsorption of nutrients is more common in Crohn’s disease than in ulcerative colitis. Crohn’s disease can affect any part of the gastrointestinal tract, including the small intestine, where most of the nutrient absorption occurs. Ulcerative colitis mainly affects the colon and rectum, which are responsible for water and electrolyte absorption.

Choice B: Both illnesses begin in the rectum. This is incorrect because ulcerative colitis usually begins in the rectum and spreads proximally to the colon, while Crohn’s disease can begin anywhere in the gastrointestinal tract, from the mouth to the anus.

Choice C: Both illnesses manifest fistula formation. This is incorrect because fistula formation is more common in Crohn’s disease than in ulcerative colitis. Fistulas are abnormal connections between different parts of the gastrointestinal tract or other organs, such as the bladder, vagina, or skin. They are caused by inflammation, ulceration, and infection that penetrate through the bowel wall.

Choice D: Both illnesses are inflammatory in nature. This is correct because both ulcerative colitis and Crohn’s disease are types of inflammatory bowel disease (IBD), which are chronic conditions that cause inflammation and damage to the gastrointestinal tract. The exact cause of IBD is unknown, but it may involve genetic, immune, environmental, and microbial factors.
