fluid rapidly?
- 14 to 16 gauge
,What is the purpose of the protective caps at each end of the administration

- vented
What gtt/mL is macrodrip tubing?
- 10 gtt/mL, 15 gtt/mL, 16 gtt/mL, and 20 gtt/mL
What gtt/mL is microdrip tubing?
- 60 gtt/mL
What kind of tubing set do you use to infuse a solution rapidly?
- macrodrip
, What kind of tubing set do you use to infuse a solution slowly?

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? Should you write
directly on the solution container with a marker? Why or why not?
- monitors IV fluid/medication delivery. You can quickly see if the rate of IV
delivery needs to be adjusted. You should not write directly on IV solution bag
as it is absorbed through the IV plastic bag
What is the difference between IV push (IVP) or bolus versus intermittent IV
therapy? Do LPNs administer IVP medications?
- IVP is a medication given directly into the IV line and is pushed over a set
time identified in IV Medication books, ie, Lasix 10mg over 1 min. A bolus is
directly pushed into the IV line at a steady rate, ie 50% dextrose. LPNs do NOT
give IVP medications
Describe how to regulate an IV infusing by gravity. How high should the
solution be positioned above the infusion site?
- 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 the slow the
gtt/ml. IV bag should be 36 inches above insertion site
What is the difference between an electronic pump and a controller?
