True/False:
Tuberculosis constitutes an important opportunistic infection among individuals infected with HIV. - True
- What is the most sensitive and specific test available for identifying persons infected w/ Mycobacterium tuberculosis?
- Tuberculin skin test w/ purified protein derivative (PPD) administered by the Mantoux method.
- What percent of lifetime risk of developing tuberculosis disease does a infected person have if there is no intervention?
- 5 percent
- What is the most effective measure to prevent the development of tuberculosis disease in a newly infected person?
- Preventive Therapy with isoniazid (INH)
- Although the preventive treatment reduces the risk of disease, does it totally eliminate it?
- No
- What is Tuberculosis?
- A disease produced by infection with Mycobacterium tuberculosis.
- What the definition of the term active disease?
- The peson has symptoms, signs, radiographic, or laboratory evidence of pulmonary, meningeal, miliary, or extrapulmonary tuberculosis.
- What is the most common form of active tuberculosis disease?
- Pulmonary tuberculosis. It causes the most concern because of the potential to transmit the infection to others by airborne route.
- What is the definition of the term tuberulosis infection?
- The person has no symptoms, signs, or radiographic evidence of active disease, but does have evidence of infection, as indicated by the presence of a positive tuberculin skin test.
- Describe the Mantoux Method of tuberculosis skin testing?
- A tuberculin skin test using a syringe and needle to inject purified protein derivative (PPD) of tuberculin.
- Describe intermediate strength dosage?
- Intermediate strength dose is is 5 tuberculin units (TU) of purified protein derivative(PPD).
- Describe low strength dosage?
- Low strength dose contains one-fifth of the intermediate strength dose (1 TU).
- Define induration?
- An area around the site of tuberculin injection that is raised and firm to touch.
- Define Tuberculin Reactor?
- A person with an area of induration to a 5 TU tuberculin skin test (or to a 1 TU tuberculin skin test).
- When should a tuberculin test be read?
- 48-72 hours afer administration of skin test.
- Define a tuberculin nonreactor?
- A person with an area of induration of less than 5 mm (usually no reaction or zero mm induration) to a 5 TU tuberculin skin test.
