A. Sputum culture for AFB: A sputum culture for acid-fast bacilli (AFB) is the definitive diagnostic test for active tuberculosis. It confirms the presence of Mycobacterium tuberculosis by identifying and culturing the bacteria from sputum, which is the most reliable confirmation of disease.

B. Chest x-ray: A chest x-ray can show lung abnormalities consistent with TB, such as cavitations or infiltrates, but it cannot confirm active infection. It is useful for supporting diagnosis but must be interpreted alongside microbiological tests.

C. Mantoux test: The Mantoux (PPD) test identifies TB exposure by measuring delayed hypersensitivity, but it does not distinguish between latent and active infection. A positive result requires further testing to confirm active disease.

D. Pulmonary function test: Pulmonary function tests assess lung capacity and airflow but are not used for diagnosing tuberculosis. They may be used later to evaluate lung impairment but have no role in confirming TB.

A. Start the client on a broad-spectrum antibiotic:Oral lesions from fluticasone are often fungal (e.g., oral candidiasis), not bacterial. Starting antibiotics without identifying the causative agent can worsen fungal infections and is not a first-line or appropriate action.

B. Encourage the client to rinse their mouth after administering fluticasone:Fluticasone, an inhaled corticosteroid, can cause oral thrush if residue remains in the mouth. Rinsing the mouth after each use helps remove residual medication and prevent fungal overgrowth.

C. Document the finding as a known side effect:While oral lesions are a known side effect, documentation alone does not address the issue or help prevent recurrence. Intervention to reduce further irritation or infection is necessary along with documentation.

D. Obtain an oral specimen for culture & sensitivity:A culture may be indicated if the lesions are persistent, worsening, or unresponsive to initial interventions. For early or mild lesions suggestive of candidiasis, encouraging mouth rinsing is the more immediate step.
