A 65-year-old man underwent an emergency laparoscopic cholecystectomy and arrives at the medical unit postoperatively with a Foley catheter. He is in stable condition, and his vital signs are stable. He is tolerating a regular diet, but his urine output is low, and he is admitted for monitoring. He has a foley catheter at this time to monitor urine output.

What procedure is appropriate in the prevention of catheter-associated urinary tract infections in this situation?
a. Remove the Foley catheter as soon as possible to minimize the risk of urinary tract infections.
b. Ensure proper hand hygiene and sterile technique during catheter insertion and maintenance.
c. Encourage the patient to increase fluid intake to promote higher urine output and flush out bacteria.
d. Use aseptic technique when emptying the drainage bag and regularly assess the need for continued catheterization.
