单项选择题
A young adult had a significant reaction to the Mantoux test. What conclusion would the nurse make from the findings（）
A. The client has active tuberculosis.
B. The client had active tuberculosis.
C. The client has been exposed to tuberculosis.
D. The client is immunocompromised.
答案
参考答案：C
解析：
A reaction to the Mantoux test for tuberculosis means that the client has been exposed to the tuberculin bacillus. Further testing needs to be done to determine whether the disease is active or dormant. A positive reaction doesn’t mean the client is immunocompromised, but clients who are immunocompromised have a high risk of tuberculosis.
