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","D"]
Explanation
Choice A reason: Documenting the color, consistency, and amount of nasogastric drainage is an important action for the nurse to include in the client’s plan of care. This can help monitor the client’s GI function, fluid balance, and response to treatment. The normal color of nasogastric drainage is clear or yellow-green. Abnormal colors include red, brown, or black, which may indicate bleeding.
Choice B reason: Encouraging hourly use of an incentive spirometer while awake is an important action for the nurse to include in the client’s plan of care. This can help prevent respiratory complications, such as atelectasis and pneumonia, which are common after abdominal surgery. An incentive spirometer is a device that helps the client breathe deeply and expand the lungs.
Choice C reason: Irrigating the nasogastric tube every 4 to 8 hr is not an action that the nurse should include in the client’s plan of care. Routine irrigation of nasogastric tubes is not recommended, as it may increase the risk of infection, tube occlusion, or aspiration. Irrigation should only be done when indicated by specific orders or protocols, or when there is evidence of tube blockage.
Choice D reason: Performing leg exercises every 2 hr is an important action for the nurse to include in the client’s plan of care. This can help prevent venous thromboembolism (VTE), which is a serious complication that can occur after surgery due to immobility and hypercoagulability. Leg exercises can improve blood circulation and reduce stasis in the lower extremities.
Correct Answer is B
Explanation
Choice A reason: Shock is not a cause of acute pancreatitis, but a possible complication of severe cases that can lead to organ failure and death.
Choice B reason: Gallstones are one of the major causes of acute pancreatitis, as they can block the pancreatic duct and prevent the flow of digestive enzymes, leading to inflammation and damage of the pancreas.
Choice C reason: Diabetes mellitus is not a cause of acute pancreatitis, but a possible complication of chronic pancreatitis, as the damage to the pancreas can impair its ability to produce insulin and regulate blood sugar levels.
Choice D reason: GERD (gastroesophageal reflux disease) is not a cause of acute pancreatitis, but a condition that affects the lower esophageal sphincter and allows stomach acid to reflux into the esophagus, causing heartburn and other symptoms.
