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?
Transplant rejection
Anaphylaxis
Bacterial phagocytosis
Hay fever allergy
The Correct Answer is A
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.

Correct Answer is B
Explanation
Choice A reason: Applying a tourniquet just below the elbow is not recommended as the first line of action for a deep laceration unless there is life-threatening hemorrhaging that cannot be controlled by direct pressure. Tourniquets are used as a last resort because they can cause tissue damage.
Choice B reason: Elevating the limb and applying ice can help reduce bleeding and swelling. Elevation uses gravity to help reduce blood flow to the injury, and the cold from the ice constricts blood vessels, further helping to control bleeding and reduce swelling.
Choice C reason: Cleaning the wound is important, but it should not be the first action taken. The initial focus should be on stopping the bleeding. Once bleeding is controlled, the wound can be cleaned to prevent infection.
Choice D reason: Applying pressure directly to the wound with a clean cloth or bandage is the first step in controlling bleeding. However, the question specifies applying pressure above the wound, which would not be effective in controlling bleeding from the wound itself.
Correct Answer is C
Explanation
Choice A reason: Metabolic acidosis is characterized by a low pH and a low HCO3. However, George's HCO3 is within normal range, indicating that metabolic acidosis is not the primary issue.
Choice B reason: Partially compensated metabolic acidosis would present with a low pH and a low HCO3, along with a low PaCO2 as the body attempts to compensate. George's PaCO2 is elevated, which is not consistent with this condition.
Choice C reason: George's high PaCO2 and near normal HCO3 suggest that his primary issue is respiratory acidosis. The body has begun to compensate by retaining HCO3, making it partially compensated.
Choice D reason: Uncompensated respiratory acidosis would present with an elevated PaCO2 and a normal HCO3. Since George's HCO3 is elevated, it indicates partial compensation.
