A nurse at a correctional facility is counseling a client who had a positive tuberculin skin test. Which of the following client statements should the nurse identify as understanding of the information?

Choice A reason: A low immune system can cause a false negative, not a false positive. Immunocompromised clients may fail to mount a reaction to the test, leading to inaccurate results. Choice B reason: Treatment for tuberculosis requires multiple medications (such as isoniazid, rifampin, pyrazinamide, and ethambutol) over several months to prevent resistance and ensure eradication. This statement reflects accurate understanding, making it correct. Choice C reason: The tuberculin skin test is read once, 48–72 hours after placement. It is not repeated within that timeframe. A repeat test may be done weeks later in certain cases, but not immediately. Choice D reason: Hospitalization is not standard unless the client has severe disease or cannot adhere to treatment. Most TB treatment is outpatient with strict medication adherence and monitoring.
