Which action is a part of the bundle of measures used to prevent nosocomial catheter-related infections?
1. Chlorhexidine is most effective when swabbed starting at the insertion site and moving outward in a circular motion.
2. It is recommended that transparent dressings be changed every 72 hours to prevent growth of bacteria on the skin.
3. Current recommendations support changing IV tubing every 48 hours on patients at risk for catheter-related infections.
4. During insertion of a central line the doctor should wear a cap and mask, sterile gloves, and a gown, and the patient should have a full body drape.

Rationale 1: Chlorhexidine is used in a scrubbing motion rather than in a circular motion.
Rationale 2: An original central line dressing should be changed after 24 hours and when soiled with blood or fluid. Central line dressings may be changed every 7 days.
Rationale 3: Current recommendations are to change IV tubing every 72 to 96 hours. Tubing may be changed more often if solutions with large concentrations of dextrose (such as TPN) are infused.
Rationale 4: During insertion of a central line the doctor should wear a cap, a mask, sterile gloves, and a gown. The patient should have a full body drape. These measures prevent catheter-related sepsis.
