A nurse is assisting with teaching a newly licensed nurse about parenteral nutrition (PN). Which of the following information should the nurse include in the teaching?
Weigh the client weekly.
Reduce the rate of the solution gradually to discontinue.
Remove solution from refrigerator 2 hr before infusion.
Shake the solution before hanging if there is a layer of fat present on the top.
The Correct Answer is B
Choice A: Weigh the client weekly. This is incorrect because the client receiving PN should be weighed daily, not weekly, to monitor fluid balance and nutritional status. The nurse should also measure the client’s intake and output, blood glucose, electrolytes, and other laboratory values daily.
Choice B: Reduce the rate of the solution gradually to discontinue. This is correct because the nurse should taper off the PN solution slowly to prevent rebound hypoglycemia, which can occur when the high concentration of glucose in the PN solution is abruptly stopped. The nurse should follow the provider’s orders or the facility’s protocol for reducing and discontinuing PN.
Choice C: Remove solution from refrigerator 2 hr before infusion. This is incorrect because the nurse should remove the PN solution from the refrigerator 30 to 60 minutes before infusion, not 2 hr, to allow it to reach room temperature. Infusing a cold solution can cause discomfort, vasoconstriction, and impaired absorption of nutrients.
Choice D: Shake the solution before hanging if there is a layer of fat present on the top. This is incorrect because the nurse should not shake the PN solution at all, as this can cause fat emulsion droplets to coalesce and form large particles that can clog the filter or cause embolism. The nurse should gently invert or roll the PN solution container to mix it if there is any separation of components.

Correct Answer is C
Explanation
Choice A: Negative Chvostek’s sign is the absence of facial twitching when the facial nerve is tapped. This is a normal finding and does not indicate hypoparathyroidism. A positive Chvostek’s sign is a sign of hypocalcemia, which can occur in hypoparathyroidism.
Choice B: Flaccid muscles are weak and limp muscles that lack tone and resistance. This is not a typical finding of hypoparathyroidism, as low levels of parathyroid hormone can cause muscle spasms, cramps, and tetany.
Choice C: Numbness of the hands is a common finding of hypoparathyroidism, as low levels of parathyroid hormone can cause hypocalcemia, which affects the nerve function and sensation. Numbness can also occur in the feet, lips, and tongue.
Choice D: Hypercalcemia is a high level of calcium in the blood. This is not a finding of hypoparathyroidism, as low levels of parathyroid hormone can cause hypocalcemia, which is a low level of calcium in the blood. Hypercalcemia can be a sign of hyperparathyroidism, which is the opposite condition of hypoparathyroidism.
Correct Answer is C
Explanation
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.
