Answer to Question 1

B
A positive reaction means the client has been exposed to TB; it isn't conclusive of the presence of active disease. A positive reaction consists of palpable swelling and induration of 5 to 15 mm. It can be read 48 to 72 hours after the injection. In clients with positive reactions, further studies are usually done to rule out active disease. In immunosuppressed clients, a negative reaction doesn't exclude the presence of active disease.

Answer to Question 2

B, C, D
General anesthesia is used to control pain (analgesia), relax muscles, and promote amnesia. Anesthesia is not used for the purpose of obtaining a reduction in risk potential; however, surgical risk is influenced by the type of anesthesia used.
