1. Nurses should always avoid contact with soiled items to prevent the transmission of microorganisms.
2. The nurse performs hand washing before and after client care to avoid contamina-tion of the client and to prevent transmission of the client's microorganisms to the nurse and others.
3. Sterile dressing changes are common practice to avoid contamination (preventing entry of a microorganism) of a new surgical incision. If the incision is not closed and becomes contaminated, it is likely to become infected.
