What is a key technique consideration for intermittent catheterization?

• A. Use sterile or clean technique with proper lubrication and void after removing the catheter.
• B. Use non-sterile technique with no lubrication.
• C. Leave the catheter in place for days.
• D. Reuse the same catheter without sterilization.

Answer: (A)

Intermittent catheterization hinges on using aseptic or clean technique with proper lubrication and ensuring the bladder is emptied after removal. Using lubrication reduces urethral friction and trauma, making insertion smoother and decreasing mucosal injury that can invite infection. Performing the procedure with sterile or clean technique helps minimize bacteria entering the urinary tract during catheterization. After removal, the patient should void to confirm complete bladder emptying and reduce residual urine, which can harbor bacteria. Leaving the catheter in place for days or reusing the same catheter without sterilization increases infection risk and contradicts the intermittent approach.
