What organization created the standard precautions for healthcare workers?

The correct choice is the CDC, or Centers for Disease Control and Prevention, which is responsible for developing and promoting standard precautions for healthcare workers. These precautions are essential in infection control practices to prevent the transmission of infectious agents in healthcare settings.

The CDC's guidelines encompass measures like hand hygiene, the use of personal protective equipment (PPE), and safe handling of potentially contaminated materials, which are fundamental to minimizing the spread of infections among both healthcare workers and patients.

While the WHO (World Health Organization) does contribute significantly to global health guidelines and recommendations, it is the CDC that specifically established the policies around standard precautions used in U.S. healthcare facilities. The FDA (Food and Drug Administration) primarily deals with the regulation of food, drugs, and medical devices, while the NHA (National Healthcareer Association) focuses on certification and training for healthcare professionals, but does not create guidelines for infection control.
