Explanation
Cytotoxic hypersensitivity is a type of hypersensitivity that involves the production of IgG or IgM antibodies that bind to antigens on the surface of cells, leading to cell destruction by complement activation or antibody-dependent cellular cytotoxicity. Myasthenia gravis is an example of a cytotoxic hypersensitivity, as it is caused by autoantibodies that target the acetylcholine receptors on the muscle cells, impairing neuromuscular transmission and causing muscle weakness.
Delayed hypersensitivity is a type of hypersensitivity that involves the activation of T cells and macrophages, leading to inflammation and tissue damage after several hours or days of exposure to an antigen. Examples of delayed hypersensitivity include contact dermatitis, tuberculin skin test, and transplant rejection.
Immediate hypersensitivity is a type of hypersensitivity that involves the production of IgE antibodies that bind to mast cells or basophils, leading to degranulation and release of histamine and other mediators, causing anaphylaxis, urticaria, or allergic rhinitis within minutes of exposure to an antigen.
Immune complex-mediated hypersensitivity is a type of hypersensitivity that involves the formation of antigen- antibody complexes that deposit in tissues or blood vessels, leading to complement activation and inflammation, causing vasculitis, glomerulonephritis, or serum sickness within hours or days of exposure to an antigen.
Correct Answer is ["50"]
Explanation
To calculate the gt/min, the nurse should use the following formula:
gt/min = (mL/hr x drop factor) / 60
Plugging in the given values, we get:
gt/min = (150 mL/hr x 20 gt/mL) / 60
gt/min = 3000 gt/hr / 60 gt/min = 50 gt/min
Therefore, the nurse should set the manual IV infusion to deliver 50 gt/min.
