What is an implanted intravenous port?

1. A device for monitoring blood pressure

2. A catheter inserted into a central vein

3. A type of chemotherapy medication

4. A method for administering oxygen

The correct answer is: A catheter inserted into a central vein

An implanted intravenous port is a catheter inserted into a central vein, usually under the skin, which allows for easy and repeated access to the bloodstream. This device is typically used in patients who require frequent infusions, such as chemotherapy or other long-term treatments. The port itself consists of a small reservoir that is connected to the catheter, which extends into a central venous structure such as the superior vena cava. This setup allows healthcare providers to deliver medications directly into the bloodstream with minimal discomfort and reduces the need for repeated needle sticks. The use of an implanted port is especially beneficial in oncology patients, as it can help preserve peripheral veins, simplify treatment administration, and enhance patient comfort during their regimen. In the context of the other choices, a device for monitoring blood pressure does not play a role in medication delivery, while a type of chemotherapy medication and a method for administering oxygen are unrelated to the function and purpose of an implanted intravenous port.
