Answer to Question 2
D
Check the patient for positional changes that might affect infusion rate, height of the IV container, and tubing obstruction. Check the condition of the site. The most likely cause of a slow-running IV is positioning. An infiltrated or clotted IV line probably will not be running at all. Discontinue the IV if it is determined that it is infiltrated or clotted off. Position will affect flow even if rate is increased. Fluid overload is not associated with slowing of the infusion rate. Often it occurs when an IV is running too quickly.
