CAMRT Radiography Practice Exam

A patient's IV bottle or bag should be hung at what height above the vein?

1. 12 to 18 inches

2. 18 to 24 inches

3. 24 to 30 inches

4. 30 to 36 inches

The correct answer is: 18 to 24 inches

The proper height for hanging an IV bottle or bag is typically between 18 to 24 inches above the level of the vein. This height ensures that the intravenous fluids can flow freely into the patient's bloodstream through gravity, which is essential for maintaining consistent flow rates. When the IV bag is elevated within this range, it creates enough hydrostatic pressure to facilitate the flow of fluids while minimizing the risk of excess pressure that could lead to infiltration or discomfort. Additionally, hanging the IV at this height allows for effective monitoring of the fluid levels in the bag and the flow rate, both of which are crucial for patient safety and care. Hanging the IV too low may hinder the flow of fluids, while hanging it too high can lead to complications related to excessive pressure. Therefore, the 18 to 24-inch range is the standard practice to ensure optimal function and patient comfort during IV administration.
