The nurse caring for a client with an IV infusing via an infusion pump monitors the intravenous site more carefully for which type of complication associated with this type of electronic infusion device?
1. Inaccurate fluid administration
2. Severe fluid extravasation if the IV site infiltrates
3. Air emboli
4. Phlebitis
2
Rationale: The infusion pump is set to deliver fluid at a specific pressure, and will continue to infuse fluid into an infiltrated site until enough fluid builds to increase pressure and set off the pressure alarm on the pump. As a result, the nurse must monitor the IV site very carefully because an IV infiltrate can continue to expand, whereas a controller flows by gravity, and will reduce flow much faster, reducing the risk of a severe acute IV infiltrate. Air emboli and phlebitis can occur with any IV infusion. Infusion pumps are more accurate in delivering preset quantities of fluid than are other methods.
