Which catheter type is designed to remain inside the body for an extended period?

• A. Drainage catheter
• B. Indwelling catheter
• C. I&O catheter
• D. Straight catheter

Answer: (B)

An indwelling catheter is designed to stay inside the bladder for an extended period because it includes a retention mechanism, typically a small balloon near the tip that is inflated after insertion to anchor the catheter in place. This allows continuous drainage without needing to insert a new catheter each time, which is essential for long-term urinary management. The other types serve different purposes: a straight catheter is used for one-time or intermittent drainage and is removed after use; an I&O catheter is used to measure urinary output over a period and isn’t meant to remain in place long-term; a drainage catheter is a broad term that doesn’t specify retention or duration, so it isn’t specifically designed for prolonged use.
