An employee who has been sick is told to stay home and not come to work. This infection control measure is classified as:

Correct answer: B. Administrative control

• A. Engineering controls modify the work environment or equipment (e.g., needle recapping devices, HVAC) — not personnel policies.
• B. Correct. Administrative controls are policies and procedures that reduce exposure risk, including sick employee policies (work exclusion), scheduling immunocompromised patients at specific times, and infection control protocols.
• C. PPE (masks, gloves, gowns) are barriers on the worker's body — not administrative policies.
• D. Work practice controls involve how tasks are performed (e.g., one-handed recapping, safe disposal). Personnel exclusion is not a work practice control.
