Before an aseptic procedure, (3) After body fluid exposure risk, and (4) Before
leaving the patient's room.
7. Does wearing gloves replace the need for hand hygiene?
A) Yes, gloves provide complete protection
B) No, gloves do not replace the need for hand hygiene
C) Only if gloves are changed between patients
