Final answer:
The best action a nurse can take to prevent CRBSI following the insertion of a CVC is to use a strict sterilization protocol and preventive measures such as hand hygiene, sterile barrier precautions, chlorhexidine skin antisepsis, and catheter site care.
Step-by-step explanation:
The nurse can best reduce the risk of catheter-related bloodstream infection (CRBSI) after the insertion of a left subclavian central venous catheter (CVC) by following a rigorous sterilization protocol. Utilizing a checklist as proposed by Dr. Peter Pronovost, which includes steps to prevent contamination during the insertion and maintenance of the central line, is crucial.
Moreover, maintaining a sterile field, practicing proper aseptic technique, and adhering to hand hygiene are essential actions to minimize the risk of CRBSI.
Some specific actions include: ensuring hand hygiene before and after touching the catheter, using sterile gloves, clean gown, mask, cap, and sterile drapes during the insertion, disinfecting the insertion site with an appropriate antiseptic, and replacing dressings and the catheter itself according to the recommended schedule or sooner if there's any sign of infection.
In the unfortunate event where CRBSI is suspected or confirmed, swift clinical action such as obtaining blood cultures, administering antibiotics, and, if necessary, removing and replacing the catheter at a different site is critical for patient recovery. Continual assessment of the central line site for signs of infection and ongoing patient education regarding CRBSI symptoms are also important preventative measures.
