Which bodily fluid has a risk of transmitting bloodborne pathogens?

The risk of transmitting bloodborne pathogens through spinal fluid is based on its potential to carry infectious agents, particularly when it is in direct contact with blood or if there is an injury that allows for exchange. Bloodborne pathogens, which include viruses like HIV and Hepatitis B and C, are primarily transmitted through blood and certain other bodily fluids that contain blood components, such as spinal fluid.

Bodily fluids that are not typically considered a risk for transmitting bloodborne pathogens include saliva, urine, and sweat. Saliva may contain pathogens, but the concentration is generally much lower compared to blood or spinal fluid. Similarly, urine and sweat are not known to transmit bloodborne pathogens because they do not contain sufficient viral loads to pose a risk for infection.

Thus, spinal fluid is correctly identified as a significant risk for transmitting bloodborne pathogens due to its direct relationship with the central nervous system and its potential exposure to blood.
