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 reason: Providing emotional support is important for a client who has ulcerative colitis, as the condition can affect their quality of life and mental health. However, this is not the priority action for a nurse who is caring for a client who is experiencing an acute exacerbation of ulcerative colitis, as it does not address the immediate physical needs of the client.
Choice B reason: Evaluating fluid and electrolyte levels is the priority action for a nurse who is caring for a client who is experiencing an acute exacerbation of ulcerative colitis, as the client is at risk of dehydration, hypovolemia, and electrolyte imbalances due to diarrhea, vomiting, and poor oral intake. The nurse should monitor the client’s vital signs, urine output, weight, skin turgor, mucous membranes, and laboratory values such as serum sodium, potassium, chloride, bicarbonate, blood urea nitrogen (BUN), and creatinine.
Choice C reason: Promoting physical mobility is beneficial for a client who has ulcerative colitis, as it can help prevent complications such as deep vein thrombosis (DVT), pulmonary embolism (PE), and pressure ulcers. However, this is not the priority action for a nurse who is caring for a client who is experiencing an acute exacerbation of ulcerative colitis, as the client may have abdominal pain, fatigue, and weakness that limit their mobility. The nurse should encourage rest and provide comfort measures such as positioning, heat therapy, and analgesics.
Choice D reason: Reviewing stress factors that can cause disease exacerbation is helpful for a client who has ulcerative colitis, as stress can trigger or worsen inflammation in the bowel. However, this is not the priority action for a nurse who is caring for a client who is experiencing an acute exacerbation of ulcerative colitis, as it does not address the immediate physical needs of the client. The nurse should teach the client about stress management techniques and refer them to appropriate resources such as counseling or support groups.
Correct Answer is A
Explanation
Choice A reason: Phosphate 5.7 mg/dL is an elevated value, as the normal range is 2.5 to 4.5 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood.
Choice B reason: Vitamin D 25 ng/mL is a normal value, as the normal range is 20 to 50 ng/mL. Hypoparathyroidism does not directly affect vitamin D levels, but vitamin D supplements may be given to help increase calcium absorption and lower phosphorus levels in the blood.
Choice C reason: Calcium 9.8 mg/dL is a normal value, as the normal range is 8.6 to 10.2 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood. However, calcium levels may be normal or near- normal in some cases of hypoparathyroidism, especially if the condition is mild or well-controlled with treatment.
Choice D reason: Magnesium 1.8 mEq/L is a normal value, as the normal range is 1.5 to 2.5 mEq/L. Hypoparathyroidism does not directly affect magnesium levels, but magnesium deficiency can cause or worsen hypoparathyroidism, as magnesium is needed for PTH secretion and action. Magnesium supplements may be given to correct magnesium deficiency and improve PTH function.
