When entering the patient's room, the CPCT should apply personal protective clothing and follow strict hand hygiene practices.
Step-by-step explanation:
When entering the patient's room, the CPCT should apply personal protective clothing, which includes a protective coat, face protection, and cut-resistant gloves. This is to prevent the CPCT from coming into contact with any potentially infectious materials in the room. Furthermore, strict adherence to hand hygiene practices should be followed, including washing hands with soap and warm water immediately after leaving the patient's room.
