What is the primary purpose of flushing an IV catheter?

Flushing an IV catheter primarily serves to clear the catheter of blood and debris. This practice is essential to maintain the integrity of the catheter, ensuring that it remains patent and free from any obstructions that could interfere with medication delivery or fluid administration. By flushing, practitioners also help to ensure that any clots or particulate matter that may have accumulated inside the catheter are removed, allowing for a smooth flow of fluids or medications.

While maintaining sterile technique, preventing infection, and ensuring proper placement are important aspects of handling IV catheters, they are not the primary purpose of flushing. Flushing specifically targets the immediate functionality of the catheter itself, thus making it vital for effective clinical practice.
