Question: 1 / 400

What is the main purpose of a Foley catheter?

To inject medication

To drain urine

The main purpose of a Foley catheter is to drain urine from the bladder. It is a flexible tube that is inserted into the bladder via the urethra, allowing for continuous drainage of urine. This function is particularly important in situations where a patient may be unable to void on their own due to surgery, urinary obstruction, or certain medical conditions. The catheter is often held in place by a small balloon that is inflated once the catheter is correctly positioned in the bladder. Thus, its primary role is to ensure that urine is properly drained, helping to maintain bladder function, prevent urinary retention, and monitor urinary output in various clinical scenarios.
