answer
with an IV pump or without (gravity)
question
What are the three things you must do when administering IV therapy without a pump?
answer
- IV set drop factor - calculate flow rate - mixing & diluting drugs
question

answer
number of drops per milliliter
question

answer
large drops per milliliter (10-20 gtt/mL)
question

answer
20 gtt/mL
question
What is the drop factor for a McGaw macrodrip set?
answer
15 gtt/mL
question
What is the drop factor for a Travenol macrodrip set?
answer
10 gtt/mL
question
What is the drop factor for a Travenol microdrip sets?
answer
60 gtt/mL
question
What is the drop factor for a minidrip set?
answer
60 gtt/mL
question
What is the formula for calculating IV flow rates (gravity)?
answer
total volume to be infused/total amount of time in minutes x drop factor = x gtt/min ml/min x gtt/mL = x gtt/min
question
Order: Hespan 500 mL to be infused over 3 hours. The drop factor is 15 gtt/mL. How many drops per minute should be given to infuse the total amount of Hespan over 3 hours?
answer
500 mL/180 min x 15 gtt/mL =
question
What are electronic intravenous regulators?
answer
IV pumps
question
What is the function of an IV pump?
answer
- delivers prescribed flow rate (mL per hour) - alarm if flow obstructed - do not recognize infiltration
question
What is the formula for calculating IV flow rates via IV pump?
answer
total volume in mL/ total time in hrs = x ml/h
question
How are answers for IV flow rates via IV pump rounded?
answer
whole numbers or rounded to the tenths
question
Order: Infuse 250 mL of 0.9% NS over 2 hours. How many mL per hour should the IV pump be programmed for to infuse 250 mL over 2 hrs?
answer
250 mL/2 h= 125 ml/h
question
Order: Lasix 80 mg, IV, STAT. Drug available: Lasix 10 mg/mL. IV infusion not to exceed 40 mg/min
answer
a. H : V :: D : x 10 mg : 1 mL :: 80 mg : x x = 8 mL of Lasix b. known drug : known minutes :: desired drug : desired minutes 40 mg : 1 minute :: 80 mg : x x = 2 minutes
question
As a nurse administering IV medications, what should you check for to ensure safety?
answer
- check every 30-60 minutes - check for kinked tubing, infiltration, flow rate, site - pump - mechanical, battery
