What is the primary purpose of a saline flush?

• A. To cleanse the IV line of medications
• B. To prevent blood clot formation
• C. To hydrate the patient
• D. To initiate a blood transfusion

Answer: (B)

The primary purpose of a saline flush is to prevent blood clot formation within an intravenous (IV) line. When a saline flush is performed, it helps to maintain the patency of the IV catheter, ensuring that it remains open and functional for the continuous delivery of fluids or medications. This action minimizes the risk of blood stagnating within the catheter, which can lead to clot formation and potential complications, such as occlusion of the IV line. While other options may touch on aspects related to IV therapy, they do not address the key function of the saline flush as effectively. Cleansing the IV line of medications could be part of a saline flush protocol, but it is not the primary reason for performing one. Similarly, hydration is an important aspect of IV therapy, yet it is not the primary purpose of flushing an IV line with saline. Initiating a blood transfusion requires specific procedures and is not relevant to the function of a saline flush. Overall, the action of flushing ensures continued access and functionality of the IV system, primarily aimed at preventing clot formation.
