Which statement about the Foley catheter’s balloon is true?

Explanation:
The main idea is how the Foley catheter stays in place and how it’s removed. The retention balloon is inflated after insertion to anchor the catheter inside the bladder. To remove the catheter, you must deflate the balloon completely before pulling it out; leaving it inflated would block withdrawal and could injure the urethra. The balloon is filled with sterile water (not air) to securely hold the catheter and to avoid introducing air into the urinary tract. This balloon is not optional—it’s an essential part of the catheter’s retention mechanism. Therefore, the true statement is that the balloon is deflated before removal.
