Final answer:
The sterile team member's function that is not appropriate is handling non-sterile items, as this could contaminate the sterile field and increase the risk of sepsis.
Step-by-step explanation:
The function that would not be one of the sterile team members is C) Handle non-sterile items. Sterile team members are required to maintain a sterile environment during medical procedures to prevent sepsis. This includes washing hands and arms, wearing sterile gowns and gloves, and functioning within the sterile field. Handling non-sterile items would compromise the sterility of the environment and therefore is not a function of a member of the sterile team.
