Final answer:
The statement is true. In dental procedures and situations where it is difficult to differentiate between body fluids, all body fluids visibly contaminated with blood and saliva should be considered potentially infectious.
Step-by-step explanation:
The statement is true.
In dental procedures and situations where it is difficult or impossible to differentiate between body fluids, all body fluids that are visibly contaminated with blood and any body fluid that may carry the HIV virus, such as saliva, are considered high-risk and should be treated as potentially infectious.
For example, dental procedures involving the use of dental instruments can result in the mixing of saliva and blood, making it difficult to differentiate between the two in case of any contamination. Therefore, it is important to follow strict infection control measures to minimize the risk of transmission.
