PSW are defined by the CDC as persons whose occupations involve

• A. Administrative duties
• B. Close personal contact with patients
• C. Laboratory procedures
• D. Food handling

Answer: (B)

This question centers on recognizing who the CDC considers PSW: people whose occupations involve close personal contact with patients. That proximity means a higher risk of exposure to infections and bodily fluids, so infection-control guidance targets these workers with specific precautions, PPE, and vaccination recommendations. Administrative roles don’t require direct patient interaction, laboratory work is typically performed in controlled settings with its own protocols, and food handling isn’t defined by patient contact in healthcare contexts. The important idea is that direct, close contact with patients is what defines the PSW category for CDC guidance.
