During catheter care, how far from the urethra should you clean the drainage tube?

• A. 1-2 inches
• B. 3-4 inches
• C. 5-6 inches
• D. 7-8 inches

Answer: (B)

The main idea is infection prevention: clean the catheter drainage tube from the urethral exit outward to reduce the chance that bacteria near the opening creep up the tube into the bladder. Cleaning a distance of about 3–4 inches from the urethra provides enough area to remove potential contamination on the portion of tubing closest to the meatus without making the process unnecessary long or awkward. Cleaning too close (1–2 inches) risks leaving bacteria near the entry point, while cleaning much farther away (5–8 inches) isn’t needed for this purpose and can be impractical. As you wipe, use a clean section of the wipe for each stroke and move away from the urethra to maintain proper technique.
