a nurse washing his or her hands

Explanation:

Universal precautions are basically the practices that are considered important to be applied worldwide in medical field. These practices aim to enhance the health of people working in healthcare sector as well as patients. These practices focus on many points that should be followed to avoid the direct contact with the patient's body fluids, by wearing masks, gloves, face shields and goggles.

The system was introduced during 1985–88 but in 1997 it was replaced with a more appropriate system of healthcare safety,called standard precautions.

As per above facts, we can clearly see that usage of gloves, masks and disposing off used needles are clearly among universal precautions. However, a nurse washing his or her hands is not a universal precaution, since it is an example of hand hygiene (although very important in healthcare sector). As per universal precautions, it is more important for a nurse to wear gloves than to was her hands again and again. However, in general body hygiene terms, hand-washing is an excellent health safety measure.
