What is a common purpose of using a Foley catheter?

A Foley catheter, also known as an indwelling catheter, is primarily used to provide continuous urine drainage. It is designed to remain in place in the bladder for extended periods, allowing for accurate measurement of urine output and facilitating the collection of urine in patients who may be unable to void on their own due to various medical conditions, surgeries, or other restrictions.

This continuous drainage aspect is essential in many clinical settings, as it helps manage urinary retention, monitor kidney function, and prevent complications related to urinary obstruction. Continuous drainage can also contribute to comfortable and safe care for patients who are immobile or recovering from surgery, where getting to the bathroom may not be feasible.

Other options, while they might relate to urinary care, do not align with the primary use of a Foley catheter. For example, flushing the bladder is not a function of a Foley catheter but may involve other procedures with different types of catheters or devices. Administering medication through a Foley catheter is also not typical practice, as medication delivery usually occurs via different methods. Additionally, while a Foley catheter can play a role in monitoring changes that might indicate infections, the primary purpose is not for detection but for continuous drainage of urine.
