When replacing an IV dressing, why is chlorhexidine gluconate preferred?

Using chlorhexidine gluconate for replacing an IV dressing is preferred primarily because it provides antimicrobial properties that significantly reduce the risk of infection at the insertion site. Chlorhexidine is effective against a wide range of bacteria and some viruses, making it a strong choice for preventing catheter-related infections.

This is particularly important in settings where IV therapy is common, as maintaining optimal hygiene can directly impact patient safety and outcomes. The use of chlorhexidine has been associated with lower rates of infection when compared to other antiseptics, which reinforces its status as a standard practice in healthcare settings focused on infection control.

While some other options mentioned may have their advantages, none equate to the critical importance of infection prevention when it comes to IV therapy.
