Which statement best describes a comprehensive approach to infection prevention in the operatory?

• A. Relying on routine cleaning by support staff.
• B. Using standard precautions, the use of PPE, proper sterilization of instruments, and maintaining a clean environment.
• C. Disinfecting surfaces but skipping sterilization when time is limited.
• D. Hand hygiene only, with no PPE.

Answer: (B)

Infection prevention in the operatory relies on a layered approach that combines standard precautions with practical steps to protect both patients and staff. Standard precautions mean treating all blood and body fluids as potentially infectious and requiring protective measures such as wearing gloves, masks, eye protection, gowns when appropriate, performing proper hand hygiene before and after patient contact, and safe handling of sharps. Instrument sterilization is essential to ensure any tools entering the sterile field are free of microbes, typically through validated methods like autoclaving. Keeping the environment clean involves thorough cleaning and disinfection of surfaces, chairs, and equipment between patients to reduce cross-contamination. When these elements are used together, the overall risk of transmission is minimized throughout every stage of care.

Relying on routine cleaning by support staff misses the protective PPE and hand hygiene components and may not address all infection risks. Disinfecting surfaces without sterilizing instruments leaves contaminated tools in use. Hand hygiene alone does not cover PPE, instrument sterilization, or environmental cleaning, so it fails to address all modes of transmission.
