Which of the following is an effective method for preventing exposure to blood-borne pathogens?

Wearing a face shield at all times is an effective method for preventing exposure to blood-borne pathogens because it provides a barrier that protects the mucous membranes of the eyes, nose, and mouth from potential splashes or sprays of blood or other infectious materials. Face shields are particularly valuable in procedures where there is a high risk of exposure to bodily fluids, as they help to minimize the potential for infection transmission through droplets that can enter the body via these routes.

In addition to physical barriers like face shields, other personal protective equipment (PPE) such as gloves, gowns, and masks also play essential roles in infection control, but a face shield specifically addresses the risk from airborne particles and splashes—enhancing safety for healthcare workers. In situations with a high likelihood of exposure to blood-borne pathogens, taking comprehensive protective measures, including wearing a face shield, is crucial for maintaining a safe environment in perioperative settings.

Other methods such as changing gloves during regular intervals or frequent use of hand sanitizer are also important practices in reducing the risk of infection, but they may not provide the full range of protection that a face shield does against direct exposure to blood and bodily fluids. Avoiding direct contact with the patient is a preventive measure, but it may not
