What action can help decrease the risk of healthcare-acquired infections in patients with central lines?

Utilizing chlorhexidine baths for immobile patients is an effective action to decrease the risk of healthcare-acquired infections, particularly in patients with central lines. Chlorhexidine is a powerful antiseptic that effectively reduces microbial skin flora, which is crucial for patients who have invasive devices like central lines. Central lines provide direct access to the bloodstream, making it essential to minimize any potential introduction of pathogens that could lead to infections.

Chlorhexidine baths help to cleanse the skin prior to the insertion of central lines and maintain a lower bacterial load in patients who may be immobile and unable to maintain personal hygiene effectively. This proactive skin preparation and maintenance not only reduce the likelihood of introducing bacteria during the placement but also help in preventing colonization and subsequent infections.

In this context, the other choices do not address the specific issue of reducing infection risk related to central lines as effectively. While minimizing the use of urinary catheters, using saline instead of total parenteral nutrition (TPN), and implementing visitor restrictions may contribute to overall infection control, they are not specifically targeted interventions for patients with central lines. Chlorhexidine baths offer a direct method to maintain skin integrity and hygiene, significantly impacting infection rates associated with vascular access devices.
