Answer to Question 1

Correct Answer: 1

The introduction of an antigen whose properties closely resemble those of host tissue results in the production of antibodies that target not only the foreign antigen but also normal tissue. This is considered molecular mimicry. Heart damage in rheumatic fever is an example of the development of antibodies against normal tissue. The other choices are explanations for the development of autoimmune disorders, but they do not describe the physiology of heart damage after rheumatic heart fever.

Answer to Question 2

Correct Answer: 1

Manifestations of serum sickness include fever, urticaria or rash, arthralgias, myalgias, and lymphadenopathy. Serum sickness can occur in response to some drugs, such as penicillin and sulfonamides. The patient is not experiencing an exacerbation of a disease process, acute influenza, or subacute rheumatoid arthritis.
