What is the primary purpose of a heparin lock in a nursing home setting?

The primary purpose of a heparin lock in a nursing home setting is to keep an IV line open. Heparin locks, also known as saline locks, are used in patients who require intermittent intravenous access without continuous fluid infusion. By maintaining a small volume of heparin or saline in the line, the lock prevents clotting within the catheter, thereby ensuring that the IV line remains patent for future medication administration or fluid delivery without the need for repeated needle sticks.

This practice is especially important in nursing homes, where patients may have frequent needs for medications or fluids, yet may not require constant intravenous therapy. Maintaining an open IV line allows for expedient access whenever necessary, contributing to better management of patient care.
