Explanation:

Identify the core question and context

The blurry text asks about healthcare workers who may be exposed to patients with active tuberculosis (TB) disease. It asks what type of testing they are required to participate in as part of a screening/protection program.

Evaluate the options

The options visible in the multiple-choice format correspond to standard occupational health protocols for TB exposure:

• Option 1: Sputum culture (used for diagnosing active TB in symptomatic individuals, not routine screening for all exposed workers).
• Option 2: Fit testing (specifically, annual respirator fit testing for N95 or other respirators, which is a standard OSHA requirement for healthcare workers exposed to airborne pathogens like TB).
• Option 3: Interferon-gamma release assay (IGRA) or blood test (used for infection screening, but "fit testing" is the standard equipment-related requirement for airborne precautions).
• Option 4: Chest x-ray (used for follow-up of positive screens, not the primary preventative respirator program requirement).

Determine the correct standard requirement

Healthcare workers who may be exposed to active TB must use respiratory protection (such as N95 respirators) and must undergo respirator fit testing annually to ensure a proper seal and protection against airborne droplet nuclei.

Answer:

• (A) Sputum culture
• (B) Fit testing (Correct answer)
• (C) Interferon-gamma release assay
• (D) Chest x-ray screening
