The nurse is caring for a patient scheduled for a thyroidectomy. Which instruction should be included in the preoperative care?

A. Iodine will be administered in the 2 weeks before surgery to increase the level of thyroid hormone being released into the bloodstream: Iodine is used to reduce thyroid hormone production and decrease vascularity of the thyroid gland, not to increase it before surgery. B. Salt should be avoided during the 2 weeks before surgery: There is no requirement to avoid salt before a thyroidectomy, and it is not part of the standard preoperative care for this procedure. C. Medications will be administered to increase the vascularity of the gland before surgery: Increased vascularity in the thyroid gland can complicate surgery, so medications are used to decrease vascularity, not increase it. D. Medications will be administered in the 2 weeks before surgery to reduce the vascularity of the gland: Iodine and other medications are often used to reduce the vascularity and size of the thyroid gland before surgery, which helps minimize the risk of excessive bleeding during the procedure.
