A nurse is providing teaching for a client who is preparing for a below-the-knee amputation. Which of the following statements is true regarding the postoperative placement of a prosthesis?

Choice A reason:
Monitoring temperature is important postoperatively as it can indicate infection or inflammation. However, it is not the immediate priority following a thyroidectomy. The primary concern post-thyroidectomy is ensuring the airway is not compromised due to swelling or bleeding.

Choice B reason:
Monitoring urination is part of postoperative care to ensure kidney function and that the body is adequately eliminating fluids. While important, it is not the priority in the immediate postoperative period following a thyroidectomy.

Choice C reason:
Pain control is essential for patient comfort and recovery. However, while managing pain is a significant aspect of postoperative care, it is not the most critical priority following a thyroidectomy. The nurse must first ensure that the airway is clear.

Choice D reason:
Airway patency is the priority for monitoring a client post-thyroidectomy. Due to the proximity of the surgery to the trachea, there is a risk of swelling, hematoma, or other complications that could lead to airway obstruction. Ensuring the client has a patent airway is crucial to prevent respiratory distress or compromise.

Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.

Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.

Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.

Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.
