A client has begun to suffer from rheumatoid arthritis and is being assessed for disorders of the immune system. The client works as an aide at a facility that cares for children infected with AIDS. What is the most important factor related to the client's assessment?

Generally interactions of  past drugs(which may be immumosupressant ) in the  client's blood streams and certain  illness usually  have great effects on the  immune system response and therefore  exposure to high risk of infection. Thus in this scenario the medical history of the client should be examined, for relevant data relating to the  drug history and illness.  Certain Corticosteroids  for treatments of  asthma, arthritis usually suppress  both inflammatory and immune response. Thus  the data(drug history)   may be a good indicator or factor  of susceptibility  of the client to illness.
