Which of the following is NOT a device used for urination assistance?

A colostomy bag is specifically designed for the collection of waste from a stoma created during a surgical procedure for individuals who have had their colon or rectum removed or bypassed. Its purpose is to manage fecal matter, not urine, which is why it is not classified as a device for urination assistance.

In contrast, the other options mentioned are directly involved in facilitating urination. A bedpan is used for patients who are unable to get out of bed, providing a way to manage both urine and feces. A Foley bag collects urine from a catheter placed in the bladder, while a bedside commode offers a toilet-like option that allows patients who may have difficulty accessing a standard restroom to urinate comfortably while remaining close to their bed. Thus, the colostomy bag stands out as the device that does not assist with urination.
