Final answer:
Saliva can potentially contain Bloodborne pathogens, especially when sores or cuts are present in the mouth, which provides a route for infection. Tears and urine are usually not considered to carry such pathogens unless visibly contaminated with blood.
Step-by-step explanation:
The presence of Bloodborne pathogens can potentially be in various body fluids. Specifically, these pathogens are present in bodily fluids through which they can be transmitted from one person to another, such as blood, semen, and in some cases saliva - particularly when cuts or sores are present in the mouth. Typically, tears and urine are not considered high risk for transmitting Bloodborne pathogens unless they are visibly contaminated with blood. However, certain situations or conditions may increase the risk of pathogen presence in these fluids.
The correct choice would be B) Saliva, especially when considering the context of contact with infected body fluids, since saliva can transmit certain infections, particularly when sores or bleeding gums are present. Tears and urine are generally not considered infectious for Bloodborne pathogens unless visibly contaminated with blood. Therefore, saliva is the body fluid among the options given that could potentially contain Bloodborne pathogens.
