How many mL per hr are ordered for the IV infusion?
75 mL/hr
This is the rate at which the IV fluid is to be administered.
How many drops per minute will be set with a drop factor of 10?
13 gtt/min
This is calculated using the DA equation for flow rate.
How many hours will a 100 mL IV infusion at 10 mL per hr last?
10 hours
The duration is calculated by dividing the total volume by the infusion rate.
How many drops per minute will be set for a 100 mL IV at 60 gtt/mL?
10 gtt/min
This is calculated using the DA equation for flow rate.
How many mL per hr are ordered for the IV infusion of 1000 mL q12h?
83 mL/hr
This is derived from dividing the total volume by the infusion period.
How many drops per minute will be set for an infusion with a drop factor of 20?
28 gtt/min
This is calculated using the DA equation for flow rate.
What is the flow rate in drops per minute for an IV of 50 mL to infuse over 1 hour with a DF of 60?
50 drops/min
This is derived from the direct conversion of mL/hr to drops/min with the given DF.
True or False: The formula for calculating drops per minute is consistent for all infusion durations.
False
The formula applies specifically to continuous infusions or those lasting 60 minutes or more.
Fill in the blank: For a microdrip with a DF of 60, the flow rate in drops per minute equals _______.
mL/hr
This relationship holds true for continuous infusions.
What is the flow rate for IVPB infusions set in?
mL per hr
The flow rate for piggyback solutions is always set in mL per hr for electronic infusion pumps.
How many mL per hr will be set on the electronic infusion pump for 50 mL in 30 minutes?
100 mL per hr
The calculation involves converting 30 minutes to hours, resulting in a flow rate of 100 mL per hr.
What is the equation to calculate the flow rate for IVPB infusions?
mL/hr = (Ordered mL / Ordered min) * (60 min / 1 hr)
This equation helps convert the ordered volume and time into an hourly rate.
If 100 mL of IVPB antibiotic is ordered over 30 minutes, what is the estimated flow rate in mL/hr?
200 mL per hr
The estimation is calculated by doubling the volume for the 30-minute duration.
What is the verification formula for calculating flow rates?
mL/hr = Ordered mL / Ordered min * 60 min
This formula is used to verify the calculated flow rate for accuracy.
True or False: The equation for flow rates must always be balanced.
True
A balanced equation ensures that the calculations are logical and accurate.
Fill in the blank: The flow rate for 25 mL of an anti-cancer drug over 30 minutes can be estimated as ______.
50 mL per hr
The estimated flow rate is calculated by doubling the volume for the 30-minute infusion.
What should be rechecked for high-volume flow rates?
Calculations
It’s important to verify calculations for high-volume flow rates to ensure accuracy.
If 80 mL of anti-cancer drug is ordered over 30 minutes, what would be the estimated flow rate in mL/hr?
160 mL per hr
This is calculated by doubling the volume for a 30-minute infusion.
What does ‘gtt’ stand for?
drop → gravity
What is the flow rate for gravity infusions derived from?
The number of mL per hr ordered
How is the drop-per-minute rate calculated?
By the nurse
What device is used to adjust the flow rate in gravity infusions?
Hand-operated slide pinch or roller clamp
What factors are needed to convert mL per hr to drops per minute?
- Number of mL per hr ordered
- Calibration (DF) of the selected tubing administration set
What are the possible drop factor (DF) values stated on the administration set package?
- 10
- 15
- 20
- 60
