Which interventions should the nurse implement to prevent a catheter-associated urinary tract infection (CAUTI)? (Select All that Apply.)

A. Obtain a urine specimen for culture every 24 hours: Routine urine cultures are not necessary unless there are signs of infection. Obtaining cultures frequently can increase the risk of contamination, which is not recommended for preventing CAUTI. B. Flush catheter system daily: Flushing the catheter system is not typically recommended as a routine intervention to prevent CAUTI unless there is an issue with catheter patency. Over-flushing can introduce bacteria into the system and potentially increase infection risk. C. Maintain a closed drainage system: Keeping the catheter and drainage system closed at all times is essential to prevent the introduction of pathogens. A closed system reduces the risk of contamination and helps maintain sterility. D. Secure the catheter to prevent movement: Securing the catheter helps prevent unnecessary movement, which can cause irritation or injury to the urethra and bladder, thus reducing the risk of infection. It also helps prevent catheter displacement. E. Begin antibiotics: Antibiotics should not be started unless there are signs or symptoms of a UTI. Prophylactic use of antibiotics can contribute to antibiotic resistance and is not recommended solely for CAUTI prevention. F. Inspect urine for color, odor, and consistency: Regularly inspecting the urine can help detect early signs of infection, such as changes in color, odor, or consistency. Monitoring for these signs allows for prompt intervention if infection develops.
