Final answer:
The cuffs of the gown are the part that is sterile during surgery. The front of the surgical gown and the sleeves, except for the cuffs, are considered sterile during surgery.
Step-by-step explanation:
The part of the gown that is considered sterile during surgery is the cuffs. The cuffs are the areas of the gown that come into contact with the sterile field and must be kept sterile to prevent contamination. This is because the cuffs may come into contact with the patient or with other sterile instruments and equipment.
