Intravenous therapy

In intravenous (IV) therapy, fluids are given through a small catheter (tube) that is inserted into a vein (intra .in; venous . vein). The IV tubing (sometimes called an “IV line”) is connected to a bag that contains the IV fluid. The fluid slowly drips through the tubing and into the vein. Usually the IV line, which is thin, is inserted into one of the small veins in the arm or the back of the hand.

IV therapy is not a source of complete nutrition, but it is useful when a person needs fluids. In addition to water, the IV fluid usually contains glucose, vitamins, and minerals. Drugs, such as pain medications or antibiotics, may also be added to the IV fluid. Sometimes, blood is given through an IV line. You will not be responsible for managing IV therapy, but you may care for many people who have an IV line in place.

SOS!

• When caring for a person with an IV line, report any of the following observations to the nurse immediately:

1. The tubing has become disconnected
2. The fluid bag is empty
3. The IV fluid is not dripping into the drip chamber
4. Blood has backed up into the IV tubing
5. The person complains of pain at the IV site
6. There is swelling or redness at the IV site
