Which type of IV is typically inserted into a small vein for short-term treatments?

The correct answer is the Peripheral IV, as it is specifically designed for short-term use and is inserted into a small vein, usually in the arm or hand. This type of intravenous line is used to administer fluids, medications, and blood products for a limited time, typically less than a week. Its accessibility and ease of insertion make it ideal for many patients requiring immediate treatment without the need for more invasive procedures.

In contrast, the Central Venous Catheter (CVC) is typically used for longer-term access and is inserted into a larger vein, often in the neck or chest, which poses a different set of considerations and risks. Non-tunneled CVCs are also intended for short-term use but are inserted deeper into the circulatory system than a peripheral IV, increasing the risk of complications. Tunneled catheters are designed for long-term use and involve a more complex insertion technique, which is not suited for short-term treatments. Therefore, the Peripheral IV is the most appropriate choice for short-term intravenous therapy in small veins.
