Answer to Question 1

B
The blood cancer leukemia is associated with radiation exposure. Bladder, melanoma, and lung cancer are associated with other carcinogens.

Answer to Question 2

D
All TSTs are read at 48 to 72 hours after the injection. A positive reading of a TST for a person who is low risk for exposure is an area of swelling 15 mm or more. For individuals who are at high risk for TB (such as recent immigrants from countries where TB is prevalent, medically underserved groups, and the homeless), swelling of more than 10 mm is considered positive. In-dividuals with a history of contact with infectious TB or who are immunocompromised are con-sidered to have a positive TST if there is more than 5 mm of swelling.
