Answer:
C. Wash your hands prior to putting on new gloves
Explanation:
When using single-use gloves you should wash your hands before putting on new gloves because you can infect the new pair of gloves if you touch them with the same hands that have touched the old pair of gloves. In other words, you should remove your old gloves, discard them, wash your hands, since they were in contact with the contaminated gloves, and put on a new pair.
