Select the appropriate answer for each question: vented or nonvented

What type of administration set (tubing) should be used for nonrigid containers (bags)? - nonvented

Select the appropriate answer for each question: vented or nonvented

What type of administration set (tubing) should be used for solutions supplied in glass containers? - vented

What is macro-drip tubing? - 10 gtt/mL, 15 gtt/mL, 16 gtt/mL, 20 gtt/mL

What is micro-drip tubing? - 60 gtt/mL

To infuse a solution rapidly, use a _____ drip tubing set - macro

To infuse a solution slowly, use a ____ drip tubing set - micro

A physician's order for IV therapy must contain what components? - Date of order, type of fluid solution, volume, length of infusion time

If medication is ordered, identify what additional components to the order must be present - Date, drug, dose, frequency of drug, length of infusion time, dilution strength

True or False:

Prior to initiating IV therapy, the nurse must check the expiration date on the solution and inspect the solution and container for particles, discoloration, cracks, leaks, or punctures. - True

What is time tape? What is the advantage of using time tape? - Monitors IV fluid/medication delivery. You can quickly see if the rate of IV delivery needs to be adjusted.

Should you write directly on the solution container with a marker? Why or why not? - You should not write directly on the IV solution bag as the ink can be absorbed through the IV plastic bag

What is the difference between IV push (IVP) or bolus verses intermittent IV therapy? - IVP is a medication given directly into the IV line and is pushed over a set time identified in IV medication books (i.e. Lasix 10mg over 1 min). A bolus is directly pushed into the IV line at a steady rate (i.e. 50?xtrose)

Do LPNs administer IVP medications? - LPNs do NOT give IVP medications

Describe how to regulate an IV infusing by gravity. - The nurse has to first figure out how many gtt/min to deliver the specific amount of fluid or the dose of medication. Using a watch with a second hand and using a manual controller to either speed up the gtt/min or to slow the gtt/min.

When infusing by gravity, how high should the solution be positioned above the infusion site? - IV bag should be 36 inches above the insertion site

Differentiate between an electronic pump and a controller. - Electronic pump controls IV fluid infusion by a computer. Controller is controlled manually (gravity drip) by the nurse.

True or False An infusion pump will stop administering an IV solution if an IV infiltrates. - False

True or False The best time to change the tubing is when the IV solution bag is changed. - True

True or False An IV running too slowly has the potential to clot. - True

True or False A sudden increase in the amount of solution infused may result in a patient's death.

• True

True or False IV tubing is tagged with the date and time to indicate when tubing replacement is necessary. - True
