___ to ____ gauge for trauma patients and those requiring large volumes of fluid
rapidly - 14; 16
,What is the purpose of the protective caps at each end of the administration set and
when should they be removed? - To keep both ends of the tubing sterile until
immediately prior to use.
Circle the parts of the IV therapy equipment that must remain sterile: - catheter,
tubing insertion spike, stylet (when intact)

(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

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% Dextrose)
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
