The nurse is caring for a patient following insertion of a left subclavian central venous catheter (CVC). Which action by the nurse best reduces the risk of catheter- related bloodstream infection (CRBSI)?
a. Review daily the necessity of the central venous catheter.
b. Cleanse the insertion site daily with isopropyl alcohol.
c. Change the pressurized tubing system and flush bag daily.
d. Maintain a pressure of 300 mm Hg on the flush bag.
A
Duration of the catheter is an independent risk factor for CRBSI, and removal of the catheter when not needed to guide treatment is associated with a reduction in mortality. Maintaining of the insertion site should be guided by institutional guidelines and is best accomplished with chlorhexidine skin antisepsis. Minimizing the number of times the flush system is opened by changing tubing no more frequently than every 72 to 96 hours reduces the risk of CRBSI. Maintaining a pressure of 300 mm Hg on the flush solution bag helps maintain the integrity of the invasive line and does not reduce the risk of infection.
