Which of the following practices is essential after potential exposure to body fluids?

Hand hygiene is the most critical practice after potential exposure to body fluids because it significantly reduces the risk of infection transmission. Proper handwashing or the use of hand sanitizer helps eliminate pathogens that may have come in contact with the caregiver's hands, ensuring a safer environment for both healthcare providers and patients. This practice is essential in maintaining personal safety and preventing cross-contamination in a healthcare setting.

Using gloves, while important for initial protection when anticipating contact with body fluids, does not replace the need for hand hygiene. Gloves can be compromised, and pathogens can transfer to the hands during glove removal unless proper hand hygiene is performed. Similarly, wearing a gown serves to protect clothing from contamination but also necessitates hand hygiene after removal to ensure no pathogens are on the caregiver's hands. Limiting contact with other residents is a good practice for infection control but does not address the immediate need for hand hygiene after direct exposure to body fluids.
