ANSWER.
20. Calculation of time taken for IV to run.
Formula
gtts/min = amount of fluid (ml) / Total time (min) * Drop factor.
From above formula
Total time (min) = Amount of fluid / gtts /min * Drop factor.
Here
Amount of fluid = 1000 ml.
gtts/min = 33 gtts/min.
Drop factor = 10 gtt.
As per formula
Time taken for IV to run = 1000 / 33 * 10.
= 30.3 * 10
= 303 min.
= 5 hr 3 min.
21. Calculation of how fast would you set the pump.
Formula
Total number of ml/ infusion time(min) = X ml * 60 min.
Here
Total number of ml = 50 ml.
Infusion time = 30 min.
As per formula
Rate of setting the pump for Zofran infusion
50 / 30 = X / 60
X = 50 * 60 / 30
= 3000 / 30
= 100 ml / hr.
22. Calculation of setting the pump for Decadron infusion.
Formula
Total number of ml / infusion time = X ml * 60.
Here
Total number of ml = 50 ml.
Infusion time = 15 ml.
As per formula
Rate of setting the pump for Decadron infusion.
50/15 = X ml / 60.
X ml = 50 * 60 / 15
= 3000 /15
= 200 ml / hr.
23. Calculation of drop rate / min needed for infuse both unit within 8 hrs.
Formula
Drop rate/min (gtts/min) = Amount of fluid /Total time (min) * Drop factor.
Here
Amount of fluid = 250 ml * 2
= 500 ml.
Total time = 8 * 60.
= 480 min.
Drop factor = 20 gtt/ml.
As per formula
Drop rate/min = 500 /480 * 20
= 1.04 * 20
= 20.83 gtt/min.
