What is the purpose of the Scrub the Hub protocol?

• A. To prevent catheter-related bloodstream infections
• B. To speed up dialysis
• C. To improve taste in water
• D. To increase blood flow

Answer: (A)

Scrub the Hub is all about infection prevention when you access a catheter. The idea is to clean the catheter hub with an antiseptic before attaching any lines so you reduce the number of bacteria at the access point. By scrubbing and allowing the antiseptic to dry, you lower the risk that bacteria will be carried into the bloodstream when the catheter is used during dialysis. Catheter-related bloodstream infections are a major complication in dialysis patients, so this step directly targets preventing those infections. It’s not about speeding up dialysis, changing water taste, or increasing blood flow—the goal is to keep the access point sterile and minimize infection risk.
