Which of the following is essential in Foley catheter care?

• A. Keep bag below bladder
• B. All of the above
• C. Maintain closed system
• D. Daily perineal care

Answer: (B)

Preventing infection in Foley catheter care relies on practical safeguards that keep urine flowing in a sterile, closed pathway and minimize bacterial exposure around the catheter. Keeping the collection bag below the level of the bladder uses gravity to prevent backflow of urine into the bladder, which reduces the risk of introducing bacteria from the bag or tubing. Maintaining a closed drainage system is essential because any opening or breaks in the system can allow microorganisms to enter and travel to the bladder. Daily perineal care helps remove bacteria from the surrounding skin and area, decreasing the chance that microbes will contaminate the catheter insertion site or ascend along the catheter.

Together, these practices address the main ways infection can occur with a catheter, so all of them are essential to proper care.
