Wisconsin CNA State Exam Vocabulary Practice

The term that best refers to a barrier between a person and pathogens like bacteria is personal protective equipment, commonly known as PPE. PPE includes items such as gloves, masks, gowns, and face shields, designed to protect healthcare workers and patients from the transmission of infectious agents. By creating a physical barrier, PPE minimizes the risk of exposure to pathogens and is essential in maintaining safety within healthcare settings. Other terms provided may relate to safety and infection control but do not specifically denote a physical barrier to pathogens. For example, barrier precautions introduce concepts related to preventing the spread of infection but do not specifically embody the protective equipment itself. Caution and standard care refer more broadly to relevant practices and guidelines without focusing solely on the protective equipment used.
