- A. Cleaning the hands after leaving the patient's room
- B. Cleaning the hands before touching sterile supplies
- C. Cleaning the hands after removing used gloves

Explanation
Hand hygiene is required immediately before an aseptic task to prevent microorganisms on the nurse's hands from entering the wound. The other actions are also important moments, but they occur after contact or after the procedure.

About Infection Prevention and Asepsis
Asepsis covers the chain of infection, hand hygiene, personal protective equipment, standard and transmission-based precautions, sterilisation, disinfection and safe waste disposal. The key distinction is between medical asepsis, which reduces microorganisms, and surgical asepsis, which maintains a sterile field during invasive procedures.
