region of induration
c. A patient with no known risk factors who has a job-related tuberculin skin test
result of a 12-mm area of induration
d. An intravenous drug abuser with a tuberculin skin test result of a 5-mm region of
induration
ANS: B
A healthcare worker who is asymptomatic has a screening TST result of 10 mm of induration during a pre-employment physical. What will the nurse reading this test tell the patient?
a. “This is a negative test, so you are cleared for employment.”

c. “You need to have a chest radiograph and a sputum culture.”
d. “You will begin taking a four-drug regimen to treat tuberculosis.”
ANS: C

c. “You must take rifampin daily for 4 months.”

c. order pyridoxine 100 mg per day.
d. recheck the tuberculin skin test to see whether it worsens.
ANS: C

b. reducing the phenytoin dose.
c. monitoring isoniazid levels.
d. monitoring phenytoin levels.
ANS: D

c. reducing the isoniazid dose
d. increasing the oral contraceptive dose
ANS: A
