The nurse is evaluating the patient's understanding of his new diagnosis of rheumatoid arthritis. Which statement reflects an understanding of the disease process?
a. "My body lacks an appropriate response to invading bacteria."
b. "My body produces an immune response to my own cells and tissues."
c. "My body immediately produces a protein that is specifically designed to fight off an antigen."
d. My body has a delayed response in which lymphocytes attack whole cells like bacte-ria."
B
When a patient has an autoimmune disease such as rheumatoid arthritis, the body produces an immune response to a "self" cell or tissue. Lacking an appropriate response is characteristic of an immune deficiency. Immediate production of a protein (an antibody) to an antigen is a normal humoral immune response. The statement involving the delayed response of lymphocytes is re-ferred to a cell-mediated response.
