Which of the following is NOT part of standard precautions?

Wearing masks in all situations is not considered part of standard precautions because standard precautions are designed to reduce the risk of transmission of bloodborne and other infectious pathogens. While masks are an essential part of infection control protocols in specific situations—such as when a healthcare worker is likely to come into contact with respiratory secretions or when aerosols are generated—they are not required universally for all scenarios.

In contrast, using gloves during procedures, practicing hand hygiene, and implementing safe injection practices are fundamental components of standard precautions. These measures are established protocols aimed at preventing the spread of infections regardless of the patient's diagnosis, ensuring a safe and hygienic environment for both healthcare providers and patients. This distinction emphasizes the importance of tailoring protective measures based on the specific risk of exposure, rather than applying masks universally in every situation.
