A patient with which findings requires drug therapy for active tuberculosis (TB)?
a. Negative TB skin test and chest x-ray but who has productive cough, fever, and shortness of breath
b. Positive TB skin test, productive cough, and a cavitation on chest x-ray
c. Positive TB skin test and a TB scar on chest x-ray
d. Positive TB skin test as the only symptom
B
A positive skin test for TB only means that the patient was infected with TB at one time. A TB scar also only indicates old, inactive disease. Cavitation and productive cough along with a posi-tive skin test are indicators of active disease that can be spread to others, and this person must be treated. The person with a negative skin test and chest x-ray but with other symptoms probably has another type of respiratory infection.
