The nurse is caring for a client receiving total parenteral nutrition (TPN). Which action is most appropriate for the nurse to implement in order to decrease the risk of infection?

Clients receiving TPN are at high risk for developing infection because the concentrated glucose solutions are an excellent medium for bacterial growth. The nurse reduces the client's risk of infection by using aseptic technique when handling all equipment and solutions related to the TPN infusion. Option 1 is a reasonable intervention for early detection of infection but does not prevent infection. Prophylactic antibiotics are not indicated for TPN infusions and can contribute to the development of secondary infections. The nurse implements option 3 to ensure that the client receives the correct infusion but is not relevant to decreasing the risk of infection.
