What is the main purpose of using a Foley catheter in a surgical setting?

The main purpose of using a Foley catheter in a surgical setting is to manage urinary output. This specialized catheter is inserted into the bladder and allows for continuous drainage of urine, which is crucial during surgery for several reasons. It helps in monitoring the patient's urinary output, providing important information regarding kidney function and fluid status. Additionally, having a Foley catheter in place can minimize the risk of bladder injury during certain surgical procedures and helps maintain patient comfort by preventing the need for frequent trips to the restroom.

While other options may involve aspects of patient care in the surgical setting, they do not directly relate to the primary function of a Foley catheter. For example, monitoring oxygen levels is typically managed through pulse oximetry and other non-invasive methods, while medication administration is generally accomplished through IV access or oral routes. Draining the abdominal cavity is typically done with different types of drainage tubes specifically designed for that purpose, such as abdominal drains or catheter systems.
