What is a key measure a nurse can implement to prevent catheter-associated urinary tract infections (CAUTIs)?

Using appropriate catheter insertion techniques and maintaining sterile conditions is a key measure to prevent catheter-associated urinary tract infections (CAUTIs) because it directly addresses the risk of introducing bacteria into the urinary tract during the catheterization process. Proper insertion techniques, which include hand hygiene, using sterile equipment, and maintaining a sterile field, help minimize the introduction of pathogens that can lead to infection.

Additionally, maintaining sterile conditions throughout the life of the catheter is crucial. This includes regular aseptic care of the catheter and the urinary meatus, as well as ensuring that the drainage system remains closed and intact. By adhering to these infection control practices, healthcare providers significantly reduce the likelihood of CAUTIs, thereby improving patient outcomes and reducing complications associated with catheter placement.

In contrast, the other choices do not adequately address the prevention of CAUTIs. Limiting fluid intake might actually worsen patient outcomes or lead to dehydration, while the option of using only single-use catheters does not directly address potential contamination during insertion or following catheter placement. Automatically removing catheters regardless of the patient's needs may not be feasible or appropriate, as certain patients may require catheterization for their care and benefit from appropriate use rather than arbitrary removal. Thus, maintaining sterile insertion techniques and conditions is essential
