Fluids given to maintain a patent vascular access are called

A. therapeutic fluids: Therapeutic fluids are administered to treat a specific condition, such as dehydration or electrolyte imbalance. They are not specifically used just to keep a vein open. B. maintenance fluids: Maintenance fluids are given to meet the ongoing fluid and electrolyte needs of a client, especially when they can't eat or drink. They are not primarily used to preserve line patency. C. replacement fluids: Replacement fluids are used to restore fluid losses due to vomiting, diarrhea, or bleeding. They are given in larger volumes and are not intended solely to keep a vein open. D. KVO fluids: "Keep vein open" (KVO) fluids are minimal infusions used to maintain patency of an IV line. The goal is not hydration or therapy, but ensuring access for future medication or fluid delivery.
