A nurse is assessing a patient's immune function by reviewing the laboratory value of the cellular response of the T cells. The nurse should recognize that which of the following conditions is affected by the?

Choice A reason: play a crucial role in transplant rejection. They can recognize and attack foreign tissues, including transplanted organs, leading to rejection. This immune response is a significant concern in transplant medicine, and managing T cell activity is essential for the success of organ transplants.

Choice B reason: While anaphylaxis is an acute allergic reaction, it is more commonly associated with the release of histamines and other mediators from mast cells and basophils. can contribute to the severity of the reaction, but they are not the primary cells involved in anaphylaxis.

Choice C reason: Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. do not directly engage in phagocytosis but can activate other immune cells that do.

Choice D reason: Hay fever, or allergic rhinitis, involves an immune response to airborne allergens, with contributing to the development of symptoms by helping to produce IgE antibodies. However, the immediate symptoms of hay fever are more directly related to mast cell activation rather than activity.

Choice A reason: This choice is incorrect because an oral cholangiogram does not involve putting a camera down the throat. That procedure is more akin to an endoscopy.

Choice B reason: This statement is correct. An oral cholangiogram involves taking an Xray examination of the gallbladder after the patient has taken an iodine based contrast agent orally. The procedure is used to diagnose problems related to the gallbladder, such as gallstones or issues with bile flow.

Choice C reason: This choice is incorrect because an oral cholangiogram does not involve putting medication into the gallbladder to dissolve stones. That description is more consistent with nonsurgical treatments for gallstones, such as oral bile acid pills.

Choice D reason: This choice is incorrect as it describes a different procedure known as extracorporeal shock wave lithotripsy (ESWL), which uses shock waves to break up gallstones.
