Answer to Question 1
C
Tuberculosis skin testing positive results is a palpable, elevated, hardened area around the injec-tion site, caused by edema and inflammation from the antigen-antibody reaction, measured in millimeters. A reddened flat area is not a positive reaction, and you do not need to measure it.
Answer to Question 2
B
Nonsteroidal drugs such as acetaminophen, salicylates, indomethacin, ibuprofen, and ketorolac reduce fever by increasing heat loss. Health care providers generally order antipyretics if a fever is high than 39 C (102.2 F). Corticosteroids reduce heat production by interfering with the hypothalamic response. These drugs mask signs of infection by suppressing the immune system. Corticosteroids are not used to treat a fever.
