IV Therapy Final Exam
questions with verified
solutions 2024-2025
What equipment and supplies are needed for initiation of IV therapy? -
answer cannulas, tourniquets, clean gloves, site cleansing agent, IV
solution, IV tubing, IV pole, extension tubing, and dressing
Using what gauge, what length catheter and in the what vein will reduce
the mechanical and chemical irritation to the vein wall? - answer smallest
gauge, shortest length, and largest vein
What gauges do cannulas range? - answer 14 to 26
What length do over-the needle catheters range? - answer 3/4 to 3 inches
What length do butterfly style cannulas range? - answer 3/4 to 2 inches
What are the advantages of using extension tubing with over-the needle
cannulas? - answer loops tubing away from the insertion site preventing
dislodgement and mechanical irritation if pulled, tubing can be changed
away from the insertion site, and decreased cannula manipulation and risk
for contamination
What gauge is used for children and elderly patients? - answer 22 to 26
gauge
What gauge is used for medical patients and postoperative patients? -
answer 20 to 24 gauge
What gauge is used for surgical patients and rapid blood administration? -
answer 18 gauge
,What gauge is used for trauma patients and those requiring large volumes
of fluid rapidly? - answer 14 to 16 gauge
What is the purpose of the protective caps at each end of the
administration set and when should they be removed? - answer to keep
both ends of the tubing sterile until immediately prior to use
What parts of the IV therapy equipment must remain sterile? - answer
catheter, tubing insertion spike, and stylet
A bag of intravenous solution should not hang longer than how many
hours? - answer 24 hours
How often should intravenous tubing be changed? - answer 72 to 96 hours
How often should IV sites be changed? - answer 96 hours
How often should a gauze dressing be changed? - answer 48 hours
How often should a transparent dressing be changed? - answer 7 days
What type of administration set (tubing) should be used for nonrigid
containers (bags)? - answer nonvented
What type of administration set (tubing) should be used for solutions
supplied in glass containers? - answer vented
What gtt/mL is macrodrip tubing? - answer 10 gtt/mL, 15 gtt/mL, 16
gtt/mL, and 20 gtt/mL
What gtt/mL is microdrip tubing? - answer 60 gtt/mL
, What kind of tubing set do you use to infuse a solution rapidly? - answer
macrodrip
What kind of tubing set do you use to infuse a solution slowly? - answer
microdrip
A physician's order for IV therapy must contain what components? -
answer date of order, type of fluid solution, volume, and length of infusion
time
If medication is ordered, identify what additional components to the order
must be present. - answer date, drug, dose, frequency of drug, length of
infusion time, and 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. - answer 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? -
answer 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? - answer 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? - answer 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
