What does the term "body substance isolation" refer to?

The term "body substance isolation" refers specifically to protecting personnel from exposure to infectious materials. This approach is primarily focused on the idea that all body fluids and substances potentially harbor infectious agents, and therefore, measures should be taken to prevent contact between healthcare workers and these substances.

This practice involves the use of personal protective equipment (PPE), such as gloves, gowns, masks, and eye protection, to create a barrier against these substances during patient care. The concept is grounded in the belief that certain precautions should be standard practice whenever there is a reasonable expectation of encountering body substances, regardless of whether a patient is known to have an infectious disease.

The other options do not accurately reflect the main focus of body substance isolation. While isolating patients from others, isolating disease patients, or quarantining those with visible symptoms have their own public health significance, they do not capture the core principle of BSI, which is about protecting healthcare personnel from potential contamination during the course of their duties.
