The nurse is caring for a client who is receiving multiple drugs for treatment of tuberculosis. The nurse teaches the client the rationale for the multiple-drug treatment and evaluates learning as effective when the client makes which statement?
A) "Multiple drugs are necessary to develop immunity to tuberculosis."
B) "Multiple drugs are necessary because I became infected from an immigrant."
C) "Multiple drugs will be required as long as I am contagious."
D) "Multiple drugs are necessary because of the risk of resistance."
Answer: D
Tuberculosis bacilli are likely to develop resistance to one drug, so multiple drugs must be used. Treatment must be continued long after the client is no longer contagious. There is no indication that the client contracted TB from an immigrant. Multiple drugs are used for all cases of TB.
