Final answer:
The statement is true; gloves are part of infection control measures and serve as a barrier to protect against the transmission of infectious diseases through body fluids.
Step-by-step explanation:
The statement that barriers used in infection control, such as gloves, should be worn when there is a possibility of coming in contact with body fluids, is true. Gloves are a crucial part of personal protective equipment (PPE) and are essential when working in environments where exposure to body fluids is possible. This helps prevent the transmission of infectious diseases by creating a barrier against various types of pathogens such as bacteria, viruses, fungi, and protozoa, that can enter the body through mucous membranes or broken skin. In healthcare and laboratory settings, the use of gloves is accompanied by other protective measures like handwashing, use of face protection, and proper disposal of contaminated materials to ensure a high level of infection control.
