What aspect is crucial in reducing the risk of CVC infection?

Proper skin preparation efficiency is essential in reducing the risk of central venous catheter (CVC) infections. Effective skin preparation involves thoroughly cleaning the area where the catheter will be inserted, which helps eliminate bacteria on the skin and prevents them from entering the bloodstream during the procedure.

Using an appropriate antiseptic solution, such as chlorhexidine, and ensuring that the skin is dried properly before insertion are critical steps that contribute to minimizing the risk of infection. This practice creates a sterile environment, reducing the likelihood of contaminating the catheter and associated infections.

While other options address factors involved in catheter insertion, such as needle angle, time taken for insertion, and the fluid used for cleaning, they do not directly focus on the primary preventive measure against infection, which is effectively cleansing the skin at the site of insertion.
