Which of the following practices is essential for handling bloodborne pathogens?

Using gloves is essential for handling bloodborne pathogens because they serve as a protective barrier between the skin and potentially infectious materials. This practice minimizes the risk of exposure to pathogens that can be transmitted through blood and other bodily fluids during procedures such as embalming or when assisting with post-mortem care.

Gloves are part of personal protective equipment (PPE) that helps ensure the safety of both the mortician and the deceased's family. Proper glove usage includes donning them before any task involving potential exposure and ensuring they are disposed of correctly afterward to prevent contamination. This is a vital step in adhering to safe protocols in the mortuary environment, where exposure to bloodborne pathogens could pose serious health risks.

The other practices listed do not provide direct protection from exposure to bloodborne pathogens, making gloves the critical choice for ensuring safety in these situations.
