Before inserting an indwelling urinary catheter, which principle is most important for preventing infection?
Correct answer: B. Maintain sterile technique during insertion
- A. Use clean gloves and touch the catheter freely
- B. Maintain sterile technique during insertion
- C. Apply antiseptic only after the catheter enters the urethra
- D. Inflate the balloon before urine appears
Explanation
Sterile technique during insertion prevents introducing microorganisms into the urinary tract. The balloon is inflated only after urine return confirms that the catheter is in the bladder, and contamination of the catheter must be avoided.
