A nurse is caring for a client who has a history of exposure to TB and symptoms of night sweats and hemoptysis. Which of the following tests should the nurse realize is the most reliable to confirm the diagnosis of active pulmonary TB?
Mantoux test
Sputum culture for acid-fast bacillus
Sputum smear
Chest x-ray
The Correct Answer is B
This is because sputum culture can identify the presence and type of mycobacteria that cause TB, while other tests can only indicate exposure or infection. Sputum culture results may take several weeks, so treatment should be initiated based on clinical suspicion and other tests.

Explanation
This is because Western blot analysis detects specific antibodies to HIV antigens and has a high specificity and sensitivity for HIV infection. CD4+ T-cell count measures the number of helper T cells in the blood and indicates the degree of immunosuppression in clients with HIV infection, but it does not confirm the diagnosis. Quantitative RNA assay and viral load test measure the amount of HIV RNA in the blood and indicate the level of viral replication and response to antiretroviral therapy, but they do not confirm the diagnosis.
Correct Answer is A
Explanation
This is because SLE is an autoimmune disorder that causes inflammation and damage to various organs and tissues, such as the skin, joints, kidneys, heart, and blood vessels. Connective tissue is a type of tissue that supports and binds other tissues and organs in the body.
